This study was authorised by letter from Mr. filliaa Ashton on 12 June 1970, in which he accepted our letter proposal of 9 June 1970. This report deals entirely with the geology and ore reserves of the Hatmondsville Mine which ia a source of cosmetic grade talc for Windsor Minerals Company. A report on Mine Safety as issued on 12 August 1970, and a report on beneficlatlon of the Haamoadsvllle ore will be issued ia the near future. A report, "Beneficiation of Vermont Talc Concentrates," was issued on 18 September 19S9 (Project Humber 290527). a Protected D o cu m in t-tu b tK t to Protective O rttr JIJ-00OS14S JN JAZK JM M 1S1 I I I I I I I I OBJECTIVE The objective of this study was to estimate an ore reserve tonnage and quality at the Hamaondsville Mine. In conjunction with this, it was necessary to study in detail the geology of the nine and the mineralogy of tbe ore material. This latter information will facilitate future mine developmant and planning. I I Protected Doeum ant-Subjcet to Protective Order J&J-0006146 JNJAZMJM W 1C1M  I SCOPE The study included an examination and detailed geologic mapping of all accessible parts of the Bamaondsville Mine. All available drill core was examined and the talcose zones were split. One half was sent to Golden for mineralogic and chemical assaying. The remainder was replaced in core boxes at Windsor. Ore reserves were estimated and, based upon the assay re~ suits, the amount of recoverable platy talc was also estimated. Flotation tests wars conducted on several samples and mlneralogic and color tasting was done on the cleaner concen trates . > I I Protected Doeument-Sufeject to Protecttv* O rder JXJ*0005147 JN JA Zi*_00M 1*184 CONCLUSIONS The reserves at the Bamaondsvllle Vine below the 860 Level are approximately 3.75 million tons of Indicated ore containing about 967,000 tons of platy talc. The mine life appears to be i more than twenty years at the present production rate. Ore quality varies greatly from area to area within the ore body. This is due to the variability in carbonate content and the inverse relationship betwesn the magnesite and talc contents of the ore. On the other hand, magnesite and chlorite contents are directly related so that, in cones of high carbonate (most of which is magnesite) the color and talc content may be expected to deteriorate. In particular, it appears that tha color of the finished product may deteriorate down-dip from the present mine workings. More drilling will be necessary to clarify this point. 4 Protect! Docnm nt-rtJ*lto Protective O rder J&J-400514* JNJAZW _W 0#1S1W SBCOMMKEDATiqyS Some additional drilling is strongly recommended. This sill be necessary to ascertain whether or not the color of the re covered talc product actually does deteriorate down-dip from the present mine workings, at the same time, much of this recom mended drilling will be Invaluable for mine planning. Limited drilling is also necessary to improve the quality of ore reserve estimates. A three-dimensional model showing the stopes in the south east end of the mine, especially on and below the S60 Level should be constructed. This would be very helpful to the mine staff. Drifts and stopes could be made of some easily worked material, such as soft wood. The dimensions would not need to be precise. The naln objective would be to show the relative positions of stopes. This would give a more clear picture as to what additional stoplng could be accomplished, at present, Ur. Winston Dezalne, the Mine Superintendent, has a remarkably good mental picture of the deposit and appears to have done an excellent job of getting high recovery from most sections of the mine. Our impression is that stoplng plans are made on the basis of visual estimates of ore quality, and an effort is made to lo cate pillars so that they contain poorer quality material. The success of the method depends largely on Sr. Dezalne, and if he should be unavailable for any reason, the operation would prob ably be severely handicapped.

The mill is approximately two miles to the southeast on the same road. Climate and Topography The area has the typical, extreme, Hew England climate. The topography is fairly rugged. Topographic relief varies as much as 1,000 feet per mile in many places near the mine. The topography appears to have been caused principally by glaciation, resulting in fairly eteap slopes on ths marginai of U-shaped valleys. The area was mostly cleared and utilised as pasture about the turn of the century but has been allowed to revert to dense forests, over most of the slopes, since that time. Mine Development The mine was originally opened In 1908 as as open pit. Id recent years, underground workings have been developed from the wall of the pit. There are now two underground levels, the 860 Level and the 950 Level, which are designated by their elevations above sea level. A third level, at approximately 760 feet above sea level, is presently being developed by the sinking of an inclined shaft. The two existing levels are fairly extensive 7 Prottctetf Docum ent-Subject to Protective Order J&J-00Q5151 JNJA25SJXW 01S1 Discussion - continued W 1 i I I I I I I I I I I i (both are over 1,000 feet in length) and are connected by any topes. The upper level, the 360, has numerous slopes extending upwards, some of which have holed through to the surface. Geology General Geology The nine is located on the north flask of the Chester Done, a part of the Green Mountain Autleliaoriun. The tale deposit is not unique, being only one of several hundred found in a fairly linear array fro* Newfoundland to Alabina. These deposits are found primarily in early Paleosoie rocks which were meta morphosed to schists, gneisses, and marbles. They were formerly sands, shales, and carbonates which were deposited in near-shore or shallow-water eugeosynolinal environments. These sediments were later overthrust from east to west to form the Vermont!a Geanticline which is an Intensely folded north-trending belt of Precasibrian and early Paleosoie rocks. The State Geologic Map of Vernont indicates that the recks adjacent to the mine area are probably Devonian (roughly 260 million years old) whereas Chidester (1991) states that they are probably Cambrian or Ordovician in age (roughly 350 to 600 million years old), Eardley (1962, p. 170) indicates that they are Silurian (between the previous two ranges) in age. 8 JaJ-0005152 Protected Docum ent-Subject to Protective Order JM JAZSSJM M tSIW  < Discussion - continued The rocks of the region are primarily metamorphosed sedi mentary rocks. However, these schists, gneisses, and marbles are intruded in many places by igneous rocks (mostly acid, or granitic). Extrusive igneous or volcanic rocks are also present. The Mount Ascutney stock, a few miles to the southeast of the mine, is a granitic intrusive body which has intruded and truncated the Standing Pond volcanies of the Devonian (Silurian?) Halts River Formation. These volcanies are reported to extend to within a mile or so of the mine and there have been a few basalt dikes noted in core from the mine area as well as within the mine workings proper. It is the author's opinion that one or mors of these igneous bodies was the source of silica, which was added to a magnesian carbonate, probably dolomite but possibly magnesite, to fora talc. The generalised reaction Is shows below; gas Dolomite + Silica - Talc + C(fe f + Soluble Calcium Salts CaXg(C<fe)a SiOa SMgOMSiOa COa Ca4* Intermediate and side reactions could have given rise to a number of products which are not shown here. Among them are brucite, chlorite, magnesite, and various clays and calcium complexes.

These are at least a fee hundred feet thick in the hanging wall of the nine. In many places they be come garnetlferoua and contain a few thin quarts veins, mineral' iaed with pyrite and pentlandite, A. few thin (six inches to three feet) basalt dikes are also present. In most places along the walls of the talc body at Hammondsville, the host rock has been converted to a chlorltic biotite schist. This may be the result of alteration along a strati graphic contact or it may represent a facies change in the pre existing rocks. This coarse-grained biotite or chlorite schist contact has been called blackwall by the miners. The blackwall schist is used as a stratigraphic marker in mining to determine the location of the edge of the ore none. It varies in thickness from a few Inches to a few feet. Where the talc pinches out between ore leases on the 860 Level, a thin layer of the blackwall can be followed from one lens to the next, nils contact should be traceable for some distance from the mine, stratlgraphically, and should aid in exploration. The talc deposit at Hasmondsvllle has a general tabular form with an average strike to the northwest and dip to the northeast at about 20 degrees. The talo bodies within the mine have a general lensold to tabular form. 10 Protected Docum ant-Subjtct to Protective Outer J&J-0005154 JN JA Z S*_ 00001S11 I I Discussion - continued There are many local variations in strike and dip of both the hanging wall and, particularly, the footwall. As a result, the ore body varies radically in its strike direction and thickness. The lenticular and pod-1ike character of the deposit is therefore, probably not the result of tight, over turned folding but, more likely, is due to variations in thick ness of the pre-talc carbonate body, hater, dynamic metamoerphlsa would have streamlined the shape during movement. The thicker parts of the ore body contain a core of chlorite and carbonate which Is actually a ebloritie marble. This has been called "serpentine" by the miners and "yards antique" by others (Cbidester, 1951). The latter term, although somewhat a misnomer, is used in this report as it describes the physical appearance of the rock quite well. Technically, however, a verde antique should contain serpentine. There has been no serpentine detected by either petrographic or x-ray analyses in either the core or the rock samples from the mine. The materiel which makes up the core of the thicker parts of ths ore body may be an intermediate alteration product from carbonate to talc or, it may be a product of retrograde metamorphism of dolonltic marble. Is detail, it appears in irregular masses, crosscutting the schistsity (see the 860 and 950 Level maps), but in the broader sense it seems to occur at a definite horizon (see CrossSection L). 11 Protected D ocum ent-Sublet to Protective Order J&J-00061S6 JN M 2N LM M 1C142 il Discussion - continued I* The very irregular nature of the footwall rakes it diffi cult to follow in developnent drifts. Consequently, it is poorly exposed in most places, or not visible at all, so that its exact position and attitude is not clear. A postulated pattern is shown diagrasmtically mi the 660 Level rap. Some layers and irregular blocks of chlorite-biotit* schist occur within tbe talc ore body and are called "cinders" by the miners. These create a problem in developnent work as they ray easily be mistaken for the true footwall of the deposit. To guard against development drifts being turned into the talc body, abort test holes are drilled into the footwall as drifting progresses. In most, and possibly all cases, where the develop ment drift has been turned away from the footwall because of cinders, the fact has bean recognised as stoping began, and mining has been continued to the true footwall. Vo a much lesser extent, developnent drifts have been deviated from tbe true hanging wall because of cinders. Again, this has usually been corrected fairly quickly. In the southeastern part of the mine, tbe ore body has a thick lenticular form, with a very irregular footwall. It reaches a maximum thickness of about 179 feet (including the verde antique core) but pinches rapidly along strike (see CrossSection 4-67 to 9-66). Down-dip, the lens seems to decrease in thickness and Increase in strike length so that its form be- 18 Protected Docum ent-Subject to protective Order J&J-O0OS156 JNJAZS6_09Q0161 I Discussion - continuad coses sore tabular with depth (Section 3-67 to 52-68) (see also talc thickness contour nap, Plate.1 and in pocket). The lens then pinches out altogether about 2,000 feet down-dip iron its outcrop at an elevation of about 500 feet. The ore body appears to pinch out abruptly and completely along its southeastern edge. Extending the drifts there nay develop a little more ore. The ore body pinches out in the central part of the nine as seen on the 860 Level but this pinchout is apparently gone R l# I f V 400 feet down-dip, at an elevation of about 650 feet, where the ore body appears to have a continuously nineeble thickness along a strike length of about 1400 feat. Along its northwestern edge, the deposit tends to split into talc layers which thin to the northwest. These are sep arated by increasing thicknesses of waste. Mining in this direction will be U n i t e d by the thickness of the thickest talc layer, rather than by the combined thickness of all the talc layers. This fact has been taken Into account in both the lsopach map of the ore (Plate 1) and in tin ore-reserve estimate. I H I Thin Section and X-8ay Analysis of Selected Bocks Thirty-eight core samples were submitted for thin-section analysis. All but a few of these were from within the ore zone. 13 Protected Docum ent-Subject to Protective Order J&J-000S1S7 JNJAZ55_00001$144 al naaifcfrr- * Plate 1 - Talc Thickness Contours (isopaeh aap) PratecM Documcnt-Sutfect le Protective Onter J&J-0008159 JKJAZSSJM001614S Protected D ocum ent-Subject to Protective O rder J&J-O006158 J N J A Z H L W O Q in tt Discussion - continued 'These were studied to determine the various rock types and to examine the relationships between the mineral phases. Some attention was paid to possible origins of the talc in order to make suggestions for further exploration work. The descriptions of the individual rock specimens will be found in the Appendix, Exhibit a . It was evident during this phase of the investigation that optical differentiation between chlorite and talc, when in fine grains, is nearly impossible. The refractive index, In oil, of the two minerals is nearly identical. The high~magnesiua chlorite which occurs within the Haamondsvllle ore body is color less, or nearly so, in thin section and is therefore nearly indistinguishable from the platy talc. Larger grains of chlorite do exhibit weak pleocbroism and may be distinguished by this property. Several thin sections were made of the host rock and, for the most part, it was found to be a Quarts-blotlte schist ex hibiting some gneissoslty. In places, this rock becomes garnetif- erous. The garnets are almost without exception subhedral and appear to have been altered to clay. In many cases, the garnets have been embayed by chlorite, indicating probable retrograde metamorphism. The subhedral character of the garnets has been studied in Vermont by students at Harvard University and has been described in the literature. These are called "rolled" IS Protected Doeum *nt-Sub)*ct to ProM e tto Order J&J-QQ0516Q JNJAZM _0000151*7 in i 1 1 2 ! I I Discussion - continued garnets with the implication that they were rolled and crushed during dynamic mstamorphisa of the country rock. The crystal Shape was assumed to have been destroyed during such treatment. It appears from the petrographic work on the thin sections that the talc has resulted from netanorphlsm of a carbonate rock. This would agree with the field evidence as interpreted by the author. A particularly convincing ilece of evidence was obtained in a thin section of material from Diamond Drill Hole Ho. 6-67 at a depth of 167 feet. A photomicrograph of a portion of that this section is shown as Plate 2. It can be seen that the talc occurs as an enbaynent in a carbonate grain. This Indicates that the tale was formed at the expense of the carbonate (magnesite). The thin skin or contact sons between the talc and the magnesite is chlorite. This Identification of the minerals was corroborated by electron-sicroprobe analysis. The results of a traverse across the embayment (line X-X' on the photomicrograph) are shown on Plate 3. Because of the partially inconclusive nature of the optical studies, x-ray-diffraction analyses were made of the rocks from which the thin sections were cut. This technique, in conjunc tion with the optical work, appears to have yielded a fairly accurate semi-quantitative estimate of the mlneralogical con stituents of each rock. In addition, x-ray analyses make it possible to differentiate between the three carbonate phases 16 J&J-0006161 Protected Docum ent-Subject to Protective Order JN JA Z !5_O D 0 01S1 lb a Plat 2 - Speaimen 6R-187 having & fine-grained talo-ahlorite embaynsnt la a carbonate particle.

The following table (Table 1) summarizes the results of the petrographic and x-ray examinations of the rooks submitted for thin-section analysis. The consensus of opinion in the available literature about the genesis of the talc bodies in Vermont seems to be that they formed as an alteration product from ultrabasic intrusive igneous rocks (Chidester, et. al., 1951; Trauffer, 1964; Gillson, 1927). Chidester (1951) however, seems to suggest that the talc at the Hammondsvllle Mine might bo the result of metamorpbisu of a carbonate body. This is the opinion of this writer. A postulated paleo-environment which would result in the formation of the Hammondsvilie ore body as we see it today may have resembled in many ways that environment found presently in the Gulf of Mexico. This environment would have consisted of a relatively low-lying land surface from which sands and muds were derived, and a fairly shallow sea (a eugeosyncline-- Eardley, 1962, p. 169) which would receive these sediments. Carbonate deposition was certainly taking place, possibly in the form of reefs. These may have been either discontinuous or eroded so that the topography resembled in many ways the present-day channeling seen in the carbonate reefs between Florida and the Bahamas.

"'Indicated ore'is ore for which tsmmsge and grade are computed partly from specific measurements, samples, or production data and partly from projection for a reasonable distance on geologic evidence. The sites available for inspection, measurement, and sampling are too widely or otherwise in appropriately spaced to outline the ore com pletely or to establish its grads throughout. - '"Inferred o r e ' is ore for which quantitative estimates are based largely os broad know ledge of the geologic character of the de posit and for which there are fsw, if any, samples or measurements. The estimates are based on an assumed continuity or repetition for which there is geologic evidence; this evidence may include comparison with deposits of similar type. Bodies that are completely concealed may be included if there is spe cific geologic evidence of their presence. Istlmates of inferred ore should include a statement of the special limits within which the inferred ore may lie." Ore reserves were calculated on the basis of 175 pounds per cubic foot of rock in place. This factor is commonly used for the California talc ore (Rassmussen, Charles Pfizer Co., Personal Communication, 1970). It also is within 10 percent of a theo retical value (McKinstry, 1949) and an empirical value obtained 24 Protected Docum ent-Subject to Protective Order J&J-0005172 JNJAZSS_000015159 X * Discussion - continued from a large piece of Hammondeville ore. The grades assigned to tbs various drill boles were obtained by assaying the avail*' able core. Those drill boles for which no core was available were assigned the average value obtained for all of the core which was assayed. The estimate does not include any ore above the 860 Level and would have to be increased by the amount of recoverable ore still remaining above that level. Ore Reserve Calculation All re-reserve estimates depend upon tbe analysis and weighting of a body of sample data. When samples are randomly spaced throughout a large deposit the question of sample weight, or volume of influence, becomes extremely significant. When properly weighted, irregularly spaced samples can provide a very precise estimate of tbe true tonnage and grade of the de posit . In the case of tbe Haamondeville ore body, the reserve esti mate is based upon data from 40 diamond-drill holes. Several methods of weighting drill-hole data were considered. Two of these,-the polygonal and the triangular area-of-influence methods 'were used independently and the results were within about 10 per cent of the. final calculation utilising a combination method. The triangular area-of-influence method is probably the simplest and most widely used method of weighting irregularly 28 Protected Docum ent-Subject to Protective Order J&J-0005173 JHJAZS6_0000161*0 I ' I I I I I I I ! I Discussion - continued spaced drill samples. The area is divided into triangles with a drill hole at each corner as shown in Plate 4. The volume is computed from the area of the triangle and the average thick ness of the ore in the three holee. A weighted average of the grade in the three holes is assigned to this volume. Extreme variations in thickness, or grade, or drill-bole spacing will distort the results obtained through the ase of this method. The polygonal area-of-influence method is quite similar to the triangular method. The polygons are developed by drawing bisectrices on each of the lines joining adjacent drill holes. His intersections of the bisectrices become the corners of a polygon with a drill hole at the oenter. The volume is deter*, mined by using the area of the polygon and the thickness of the ore intersection in the drill hole. Qrade of the material in the drill hole is assigned to this volume. As in the triangu lar area-of-influence method, the wide spacing of the drill holes causes problems. With polygons only, an Inordinate area of influence is assigned to some of the drill boles because of the wide spacing, and the aethod was not used for this reason. The areas of influence obtained through the use of this aethod of weighting are shown in Plate 9. Other methods of calculating reserves involve the use of isopachs (contours of equal thickness) or cross-sectional areas 26 Protactad Docum w tf-Sutycclto Protoctfv Order J&J-0006174 JNJAZ56 00M15161 Plate A ~ Triangular Areas of Influence protected D ocum ent-Sutyw t to Protective Order J&J-000S175 JNJAZSS_00001S162 1 Protected D oeum tn-Sub)t to Pretteflv* Ordr J&J-0005176 JNJAZSS_0O 0015183 Plate 5 - Polygam!

Usually, these methods assume a uniform grade throughout the tire deposit. The method used In calculating ore reserves for this re port combines two different techniques and is thought to be the most realistic method of calculating ore reserves for the Ham monds vilie Mine. The method involves combining the isopach map of talc thicknesses (Plate l and in pocket) and the polygonal areas of influence of the various drill holes (Plate 5). The area for each polygon was combined with the thickness from the isopachs to obtain the volume; the ore grade within the appropriate polygons was assigned to the respective volumes. These values were then totaled to give the weighted ore reserve estimate. The advantage of this technique is that the variation in grade is assigned to an appropriate volume based upon the poly gonal area of influence of the drill boles and the more accurate volume is obtained from isopachs. In preparing the isopach map no corrections were made for the dip of the ore body because it was generally shallow dip. Deviation of the drill holes seems almost a certainty. The ma jority of the core examined indicated that the vertical holes had deviated enough to intersect the schistosity of the ore and host rocks at a nearly perpendicular angle. This is frequently 29 Protectsd Docum ent-Subject to Protect!* Order J&J-0005179 JNJAZMJW M1S186 Plate 1 - Talc Tbicknes Contour (isopaeh nap) Protected Docum ent-Subleet to Protective Order 30 J&J-0005180 JNJAZM JJO 0015187 3 S n i o I i i  V I I Discussion - continued a problem when drilling in schistose or gneiss!c rocks. An examination of the isopaoh map, Plate 1 seens to indicate that the minimum-ninlng-thlekness contour (nine feet) on the southeast side of the nap is displaced almost 100 feet to the east. This contour was drawn on tht basis of drilling information and was modified slightly on the basis of information available from the mine workings in that area. There is pre sently not sufficient evidence to mdve this contour to the west. The difference in reserve tonnage if this contour were moved would probably be less tbas 100,000 tons. ore quality In order to determine tbe quality of the ore reserves within the Hamaondsvilie Mine,.it wee desirable to carefully sample the available diamond-drill core. One hundred and seven samples wsrs sawed from the core from l? different drill holes. These were submitted for chemical, minerslogical, and petrographic analysis. A selected few of these samples were submitted for more exhaustive analysis after flotation testing. In addition, almost forty samples of core material were submitted for thin-section analysis to determine various infor mation about the host rock, the ore, and tbe origin of the de posit. lbs results of these analyses have been discussed under 31 Protected Docunw rt-Subjoct to Proev O rd*r J&J-00051S2 JNJAZMLP0001S1t t  n I i Discussion - continued Thin Section and X-Ray Analysis in the section on Geology. The only chemical test performed on the core samples was a determination of the acid solubility. This was done by the standard Johnson and Johnson procedure in the laboratory at Golden. The results are shown in Tables 2 through 18. X-Bay diffraction analyses were perforate! on ground samples of rock. All peak heights reported in the tables were measured in centimeters above background directly from x-ray diffractograms. Tbe principal peaks of the various minerals are re ported so that, in tbe case of talc, chlorite, and mica, the relative height above background (intensity) of these minerals are roughly comparable to relativa abundance of the three min erals. It should be pointed out that these numbers do not represent percentages of the various minerals. The percentages of the variauB minerals, as determined optically, are reported in Tables 2 through 18 and represent the microscopic estimate of the amount of the mineral present on slides of the insoluble residues from chemical testing. The purpose for doing microscopic analyses on tbe insoluble resi dues was to eliminate the problem of identifying the abundant carbonates (other than by x-ray means). The residues were al most entirely silicates, mostly talc and chlorite. The differ entiation between these two, as stated earlier, is very difficult 3^ Protected Docum ent-Subject to Protective order J&J-0005183 JNJAZS5_00001S170 Interval (ft) 39.041.0 X-Ray Diffraction Peak Heights Ta lc TremoliteActlnolite 23.8 -u Chlorite Quartz 1.2 r * Calcite Dolomite Magnesite Mica -- 3.4 4.5 -- 47.054.0 19.8 tte *' 0.8 -- -4.

The results of color testing on the cleaner concentrate from these samples (Table 19) indi cated that the color quality may deteriorate down-dip .in the ore body and were reported by letter to Mr. Vllliam Ashton on 21 September 1970. At that time five more samples were selected from diamond-drill holes So. 38-67 and So. 39-67 to check tfets I possibility in an area in which mining will soon commence. It can be seen that the color values obtained from the I seven samples from these two holes are below the standard . value of 85.5 which has been set for the ore from the Hammonds- ville Mine. I Four samples were selected from the verde antique or so- called "serpentine" core of the ore body. These samples were I from Diamond-Drill Hole 37-67. The purpose for taking these four samples was to ascertain if this material could be mined and I blended with other ore from Vermont and still yield an acceptable I product. This would increase the ore reserves if such a procedure were possible.

There are obviously, however, sone sones within the verde antique core which would be very low in whiteness and thus unusable as oye. These are thought to be near the margins of this material. More ampling and testing would be necessary to fully evaluste this posslblity. The color values obtained froa the various samples ere shown on the graph (Plate 8).

Drilling Recommendations Of prisary importance in say davelopaent drilling program is the acquisition of knowledge which will be useful for mining. Subordinate to this is the seed to (Atain information about the remainder of the ore body. There appears to be no immediate need for drilling out the entire deposit on closer centers unless the long-range plans of the company would ba affected by laying a sore complete and accurate picture of the reserves and ore quality. At the present time, the ore reserves are classified as Indicated and it would take a great deal more drilling, probably three or four times the existing amount, to raise the classification of this reserve ore to the Measured category.

As has been pointed out in the section on Ore Quality, there i is eone concern that the color nay deteriorate down-dip within I the ore body. Drilling to obtain mere Information os this prob lem seams to be quite important. There is so doubt that tba i management at Windsor Minerals will be in a bettar posit** to lay out these boles than the Research Institute but our ideas ' i are presented here for their evaluation, light diamond drill i hales have been suggested on the 860 Level (see' Proposed Dianond Drilling 30-Seal overlay map in pocket). These boles will not only allow evaluation of the quality of the tale below the 880 Level but will be of great assistance in mins planning for the i next level down (770 Level 7). In order to evaluate tbe quality i of tbe ore insofar as product color goes, these holes should be diamond drilled. The core in the ore zones should be sewed* i lengthwise and half should be uaed for the color assay. The use of .a core splitter is not recommended because of the nature of i tbe ore. It tends to exfoliate in a splitter and for this reason, a good aplit Is impossible to obtain. It may be desirable to utilize the entire core for assay but this is often a mistake ss more information is desired at a later date and duplicate holes might have to be drilled. 88 Proltc tv l Dceum nt-Bubjctto Protective ordr J&J >0006211 JNJAZW _00001H9B  % Discussion - continued The location of these holes Is shows os both the overlay plan (Proposed Dianond drilling) and on Cross-Sections J, L , and If. These holes can either be drilled vertically or at 90 degrees to the sefaietosity (the dip of the ore). The proposed depths are shown on the overlay but each bole should be drilled at least 20 feet into the Quartn-biotite schist to be certain that the foot- wall and not a cinder, has been penetrated. In. addition to the above drilling some surface holes seen called for. this would not only be for clarification of the eolor Question but for nine planning on the next level. On the basis of the apparent physical shape of the ore body (see tbe Map of Talc Thicknesses, plate 1) several areas can be seen in which drill holes would furnish a naxinun of information. Pour of these are listed below: 1. * near the center of the triangle fornsd by holes 58-68, 6-66, and 57-68. S. halfway between holes 58-68 and 10-86. This would be to evaluate the width of the apparent plnehout as wsll as ors Quality. The hole should be placed sonewhat to the east of the plnehout sons If possible. 3. approximately 800 fast west of hols 38-67. This should be about 1b the thickest part of the ore body and would be very lnportant in evaluating ore Quality. 4 . approximately 885 feet 8 80 S of Bole 10-86. This hole would evaluate not only color but the shape and else of the thickest portion of the ore body. m P ra fc c M Doeum m -9ub(*ct to Protectfv* Order J&J-0DD6212 J N JA Z N L M 1 in 1 Discussion continued These holes, considered by us to be a bare minimum necessary for reasonable mine planning for the next five years or so, should give a maximum of information return for a rather United amount of drilling. The philosophy behind the locating of these holes is readily applicable to the location of several more, if they seen necessary. Any drill holee which are drilled t o depths of sore than 300 fast should be surveyed. It is not uncommon for drill holes in this type of rock to deviate from the vertical is less than 300 feet. The Tro-Pari method of surveying is probably the most practical; Eastman is probably bettor but more expensive. It can be seen iron Cross Section F that something of long* range interest takes place around Drill Bole S7-S. Not only does the thickness of the ore Intercept increase but there is apparently some structural change in that area. The ore body nay undergo a reversal of dip is this area or it nay have been faulted somewhat. Bore drilling will be necessary In this area and to tba north to answer these questions.

EXHIBIT 2 PETROGRAPHIC m M l H A T i a t S Glossary; The following definitions of terns used to describe rocks and thin sections are furnished for the conven ience of the reader. Foliation -- A laminated structure resulting froa segregation of different minerals into parallel hgars. Schistositv -- Synonoaoue with foliation when used to describe the structure of schists. Lioeation -- Harrow streaks of minerals, or mineral fragments, Strung through a rock as disconfclwous hut parallel lines. Spar Type Carbonates -- A carbonate particle that has not been granulated,"l.e., uncrusfaed (or possibly epigenetic) carbonate particle. Granulated Carbonate -- Carbonate partlclee that are derived iron the crushing of larger spar type carbonate particles. Augen -- Largs lenticular aineral grains o r aggregates of minerale which in cross-section have the shape of an eye. Retrogressive Metanorphism -- Includes the changes that taka ' place whence rook, teat as formed by relatively Intense metaaorphism, is altered within an environment of lowergrade metamorphisa. Gneiss -- A coarse-grained rock in which bends rich in granular minerals alternate with bands in which schistose minerals predominate. Schist -- A medium- or ooaree-gjrained metamorphic rock with Subparallel orientation of aleaeeous minerals which dominate its composition. Marble -- A metamorphic rook composed essentially of calcite and/or dolomite and/or magnesite.

Schistose Barbie -- A rock containing aore than 60% carbonate particles intermixed with seams of schistose material. Marble Schist -- A rock containing less than 60% carbonate particles intermixed with large areas ar seams of schistose material. Sample Descriptions: She specimens submitted for thinsection analysis are described below, Bach rock is described' macroscoplcally, then the details of the petrographic analysis follow. The numbers applied to the samples (such as 2H-301) indicate the drill-hole number from which the sample was taken (i.e., drill hole 2-67H) and the depth within that hole at which the sample was taken (i.e., 301 feet). Bleven holes were drilled in 1966 (1-66H through 11-66H) bat the core was not retained. In 1967, drilling cooswaced again with hole HO. 1-67H. All of the sample- numbers used herein refer to drilling during 1967 and 1966. i - m * Protected Docum ent-Subjectto Protective Order J&J-00A6240 J NJAZW _0Q 0#1 S227 Exhibit 2 - continued Specimen 2H-301; In hand specimen this is a grayish black rock exhibiting a schistose structure.

In thin section the rock consists of a moderate amount of llneated mica laths (possibly biotite) intermixed with a moderate amount of granulated quartz and a minor amount of granulated feldspar particles (Photomicrograph lA). 411 minerals show seme degree of straining. The light brownish gray phenocrysts noted in hand epecimen appear as fine-grained, opaque clay-like particles with chlorite inclusions progressing from the contact with the hoat rock inward (Photomicrograph IB).
