FILE MEMORANDUM MINE CANYON PROSPECT WHETSTONE MOUNTAINS COCHISE COUNTY, ARIZONA Old Claims

On Friday, January 20, Mr. B. J. Devere and I visited the courthouse in Bisbee to investigate the possibility that the Kalafs (BS&K Mining Company) might once have been interested in the Mine Canyon Prospect.

in 1956 some 45 claims were recorded under the name GSB Mining Co. by George Kalaf. These claims were re-recorded in 1957, also by George Kalaf. These claims cover the prospect. Mr. Trappman, bulldozer owner- operator from Elfrida, has advised us that "Silver Bell people" did considerable work and drilling during that period of time (1956-57).

No afidavits of labor were recorded by the Kalafs. We do not know if the Kalafs still alledge some interest or rights in the property.

Mr. Ramsey, foreman at the Sands Ranch, advises us that the "abandoned" blue road grader on one of the old drill roads was brought into the prospect about 18 months ago, and was used to grade the roads. Last fa l l (1966) these people returned and drained the radiator to prevent i t from freezing.

Mr. Bowditch advises us that claim notices found in the f ie ld were not valid. I t is d i f f i c u l t to envision some person or persons expending money on mining claims without presuming to have some ownership r ights. I t is at least conceivably possible that such persons could represent the Kalafs. If such is the case, we would be in the potent ia l ly embarrassing position of doing road work, and d r i l l i n g on ground to which we do not have mineral t i t l e .

An exhaustive record-ownership search may be in o r d e r .

MINE CANYON PROSPECT WHETSTONE MOUNTAINS COCHISE COUNTY=,ARIZONA

Dear S i r :

Enclosed is Mr. Yon Fayls repor t on the Mine Canyon copper prospect s i tua ted about 20 mi les west of Tombstone and 15 miles north of Ft . Huachuca.

Mineralization consists of thin, close-spaced seams of chalcopyrite, occupying shears which form a zone 400 feet wide and 3000 feet long. Although the monzonite is essentially unaltered and the pyrite content very low, some leaching and migration of copper has taken place --- as evidenced by seams of limonite after chalcopyrite in outcrops with no copper stain. In road cuts penetrating 5 or 6 feet below the outcrop and in the bottom of a deep canyon, chalcopyrite and copper stain are present, but some leaching has taken place and thus the copper content of this material may be much less than the sulfide zone at depth.

An average of about I% copper as cha icopy r i te w i th traces of cha i - coc i te was obtained in an underground working c rosscu t t i ng the zone fo r a d is tance of about 35 fee t - - - the l i m i t of penet ra t ion . This may represent the best pa r t of the zone; however, there is the p o s s i b i l i t y that values fo r a width of 3001-4001 would average up to a mineable grade.

Only a small amount of drilling is required to make a preliminary test of continuity and grade, and I agree with Mr. Von Fay that such should be undertaken.

Estimated costs:

l . Surveying, se t t i ng corners 20 claims 2,500.

• 2, Three holes, total 1200' @ $10/ft. 12,000.

3. Sampling, superv is ion, roads, etc . 5~500.

Total $20,000.

I f you approve, please request a mining au tho r i za t i on in the amount of $20 ,000 .

Yours very t r u l y ,

A~ERICAN SN~LTING AND REFINING CONPANY Tucson Arizona

January i0, 1967

TO: J.H. COURTRIGHT

FROM: S. V0N FAY

MINE CANYON PROSPECT WHETSTONE MOUNTAINS COCHISE COUNTY. ARIZONA

Summary and Recommendations

Twenty claims have been staked in the Whetstone Mountains, covering a copper bearing shear zone which appears to be about 3000 feet long and 400 feet wide. The zone is in fresh monzonitic rocks, in mountainous topography, but close to highways and other facilities° Rocks are poorly exposed, being covered by talus and soil. Oxidation is shallow, and a few underground workings show some residual chalcopyrite, as do some arroyos, with minor pyrite. Limited sampling in underground workings shows ore grade values. It is recommended that the claims be validated, three angle diamond drill holes totaling about 1,000 feet be drilled as an initial test of the zone and the area be mapped in detail. In addition, an option should be obtained on two old patented claims. An authori- zation of $20,000 should accomplish the claim validation, drilling, and mapping.

In September, 1966, Mr. B. J. Devere and myself paid an initial visit to the prospect. The visit was occasioned by Mr. Devere's recollection of a specimen of chalcopyrite bearing igneous rock purporting to come from the Whetstone Mountains. In addition, a porphyry note by Ko G. Papke mentions an alledged spotty occurrence of chalcopyrite, bornite, and pyrite in a tactite, from which some +$100,000 of copper ore was produced prior to and during World War I.

Two old patented claims, the Mascot and Nevada, Mineral Survey 2246, cover the old occurrences in tactite. Known mineral occurrences in these, and other tactites do not appear to be of interest. The prospect is in National Forest, in Section 20, T19S, R19E. Two claims were staked in November for initial protection, but not recorded. Twenty claims, Stone 4 through Stone 22 have now been staked to cover the zone (see map).

The prospect has been mapped in a reconnaissance fashion to determine limits of mineralization. It consists of a shear zone in monzonite slightly over 3,000 feet long and about 400 feet wide. Dips

Mr. Courtright -2- January I0, 1967

of individual shears are high angle, passing back and forth through vertical, and resulting in a slightly sinuous strike, which approxi- mates N53OE. The shears are mineralized with chalcopyrite and lesser amounts of pyrite. Individual shears are thin, ranging from paper thin to about 1/4 inch, and rarely~l/2 inch thick, but are relatively continuous. Spacing between shears varies between ~1/2 inch to 6 to 12 inches. The closest spaced shearing occurs approximately in the center of the zone over a width of at least 50 feet. Samples taken from an old adit in the middle of the zone average about 1% Cu. Grades appear to decrease with the decrease in shearing intensity from the central higher grade zone to the edges of the shear zone. Disseminated sulfides are negligible, except in the central zone, where they appear in poikolitic feldspars, mica books, etc.

The expectable Cu grades in the leaner portions of the shear zone are difficult to appraise. Rock on the outcrop is essentially fresh, with minor feldspathization and possible recrystallization. Copper stain is almost non-existent, although diligent search will usually reveal traces of green or black copper oxides. Shear faces are usually covered with limonites of a color and texture such that they appear to be after chalcopyrite. This cannot be strictly correct, as some pyrite is noted where sulfides can be found.

Chip sampling of leached rock in a road cut (upper road), two to ten feet below soil and on dip above material sampled in an adit, shows a grade of about .21% Cu. The corresponding rock in the adit shows .41 to .53% Cu, and is about one-half leached and oxidized. This indicates something over a twofold increase between the road cut sub-outcrop and the adit, with the adit grade being downgraded because of leaching. Extrapolating from this basis, and observing the grades obtained in the road cut sampling, one can arrive at a grade of about .5% Cu for the weaker portion of the zone. This is a questionable exercise in arithmetic involving too many variables to accept with any confidence such a copper grade. The sampling done, however, does appear to point out that there has been some actual removal of copper from the outcrop, rather than precipitation in the immediate surround- ing rock as copper oxides.

Hard, polished, outcropping rock in a gully below the road cut, containing some sulfides shows grades ranging from~o29 to .71% Cu (samples MC50-MC53). The tactite inclusion to the northwest of these samples shbwscon~derable carbonates, and was not sampled. Dump samples MC16 and 23 to the southwest show copper is present. No sulfides were noted on these little dumps, and Cu stain is very minor. Very little outcrop occurs on the lower road, and this was not sampled.

The grades in the leaner portion are critical. If they are .2% Cu, the prospect has no value. Grades as high as .5 or .6% Cu in the lean portion together with possible moly and precious metal credits would make the prospect of decided interest. Considering the occurrence of fine grained sulfide disseminations where the grade

Mr. Courtright -3- January I0, 1967

approaches 1% Cu, erratic shearing intensity with strong variations in thickness of chalcopyrite-pyrite on the shears, I would doubt if a consistent and accurate grade appraisal of sulfides in core to say nothing of leached outcrops could be made without assaying.

Mineralization is evident on the surface through a vertical range of about 750 feet. In the area sampled, continuity of mineralization is demonstrated over a length of about 800 feet and appears to continue, based on talus float, and sparse outcrops, for at least another 1400 feet to the southwest. To the northeast, from the area sampled, outcrops are poor, and talus is blocky. However, sulfides continue in a gully bottom for some hundreds of feet northeasterly from the area sampled, and are then lost. Farther northeast, sulfides again can be noted in a gully bottom near the old patented claims. Between these two points, discontinuitymay occur. Beyond the northeasternmost gully mentioned, the zone appears to be feathering out into alternate bands of about 75 feet wide of mineralized and unmineralized rock.

In the area from which samples have been obtained over a length of 800 feet, and a width of 400 feet, about 10,O00,O00 tons would be present to a depth of 400 feet.

It is my opinion that the grades in the leaner portions of the zone may range as high as .4 to .6% Cu and therefore the prospect warrants a limited initial test. If such grades do occur, the deposit would be amenable to open pit mining. Physical conditions for such mining are ideal. Haulage would be down hill. The prospect is within about 4 miles of two major highways, about 5 miles from railway trans- portation, overlooks the San Pedro Valley, and its ample water, is close to power etc.

A limited test is suggested consisting of three +_300 foot long diamond drill holes. These holes are designed to cut a portion of the lower grade material and check part of the center of the shear zone. They will not crosscut the entire zone. They are shown as P. l, 2, and 3. These proposed holes are angle holes (-45°), to be drilled with a skid rig. The holes are also designed to satisfy discovery requirements for the new claims. Concurrently wlth this initial drilling, a detailed mapping program should be undertaken.

It would be desirable to investigate the status of the patented claims and obtain an option, if possible. They have no apparent mineral worth, but are in an awl~ard physical location in respect to access at the end of the shear zone. Local real estate values within a very few miles of the claims approximate $200 to $300 per acre for parcels outside National Forest. Somewhat higher values might be attached by owners to land inside the forest.

Introduction

Some ten years ago Mr. B. J. Devere was shown a piece of chalcopyrite bearing igneous rock by a bulldozer operator then building a road in the Whetstone Mountains. In a porphyry note dated July 1952, Mr. K. G. Papke mentions an alleged spotty, irregular occurrence of chalcopyrite, bornite and pyrite in tactite. In the light of these two items of information, Mr. Devere and myself visited the area.

Summary and Recommendations

A cha!copyrite bearing zone/zones, in unaltered monzonite, with a bornite bearing tactite near one end has been noted.

It is felt there is a reasonable chance that commercial tonnages and grades may be present.

Present status of patented and unpatented claims should be determined, and a hold should be obtained, if they are avaTlable for reasonable terms.

After determination of land status, detailed geological mapping and minerai appraisal should be undertaken, using aerial photographs as a base.

Once mapping is underway, we should claim open ground and do bull- dozing to uncover outcrops.

General

The area o'f interest is primarily in unsurveyed Section 20, TIgS, RIgE, in National Forest, in the southern portion of the Whetstone Mountains. Some production (~$I00,000) of copper was made in World War I by the Twin Peaks Mining Company, and/or preceding companies known as the Mascot-Nevada and Noriega properties.

One old patented claim "Mascot-Nevada", survey number 2246, exists. This was also known as "Gallens Patent". The Noriega Claim was also probably patented. Other patented claims may exist. Recent claim activity includes a location for the Double S S Mine, located 8/20/65 and recorded 8/22/65by K~ Shull and A. Samuels. Mr. Samuels, with whom I am acquainted,

operates the Fair Store in Benson, Arizona.

Some churn drilling (2-3~holes?) was done circa 1956-57, ~y parties unknown, in poorly advised locations. We also have reason to believe that Utah Construction has done geological mapping in the area.

Copper occurrences consist of thin (~ I/8 '~) vertical veinlets, bearing chalcopyrite, with scanty pyrite, in a fresh, unaltered, medium grained monzonite. One zone of veinlets is about 400 feet wide, and has a minimum strike length of about 800 feet, open on both ends.

ThTs particular zone consists of a "high grade" middle portion •about If0 feet wide, where the copper content should range between .6-I.00% Cu, with veinlets less than one inch apart. One sample was taken from dump material from this higher grade portion. The sample consisted of rock bearing chalcopyrite veinlets, leached veinlets, and traces of malachite- azurite, and assayed .87% Cu, .01 oz Au and tr. Ag. Outside the middle high grade portion of the zone, the veinlets are wider spaced, up to or about eight inches apart. A sample of about 200 feet of the lean material, taken in a road cut, shows .42% Cu, tr. Au, .12 oz Ag, and .002% MoS2.

The zone strikes N60-70E, where seen, open at both ends. Other paral- lel and sub-parallel zones may exist, 'as evidenced by faint color anomalies. Cross-cutting sets of mineralized fractures also •eXist, ~hich appear to correspond in grade to the higher grade port'ions of the major NE trend. These sets do not appear~to have lower grade edges, and are narrow, ranging from about 5 to 75 feet:~in width.

Approximately one-half mile frem the portion of the zone sampled, on strike, the zone cuts across a zone of small to very large sedimentary zenoliths which strike abouteast-west. In a~d adjacent to the chalcopyrite bearing northeast fracture zone, the zenoliths are altered to tactite. The tactites contain large blebby bornite and finely disseminated bornite, with rare chalcopyrite, and little or no pyri-te, as shown by dump material from

~ . ~! ~

old workings. On the outcrops, volds after copper bearing sulfides, with melaconite, are present.

West of this garnetized and mineFa•|ized area the zenoliths are not garnetized, but bear enough pyrite to give a red color anomaly. Only rare traces of copper sulfides have been seen (Cpy and Bo) in the pyritized zenoliths, and no commercial potential is thought to exist.

The copper bearing rocks in the main northeast trend show non-descript outcrops, with no significant color anomaly, thin brown limonite bearing cracks, and normally no copper minerals on the surface of the rocks.

In the mineralized portion cited, for a 400 foot width, a strike length of 800 feet, and an arbitrary depth of 400 feet (outcrops show a vertical topographic range of about 150 feet with no m'neralization change), there is room for a possible ten million tons, with a possible grade of .4 to .5% Cu,

It is felt "that this potential, taken together With the mineralized tactite, and other sub-parallel and cross-cutting copper bearing zones, gives sufficient encouragement to warrant a careful and detailed geo- logical study to see if exploration targets do in fact exist, or can be developed.

It is recommended that aerial photographs be obtained for Sections 19, 20, and 30, at about 800 feet to the inch, and that the appropriate portions of Section 19 be blown up to 400 feet to the inch, or 200 feet, if required.

Accessible underground workings should be mapped and sampled.

A land study should•be made to determine the' status of patented and possible unpatented claims, and a hold'should be obtained on such claims, assuming reasonable deals can be obtained.

Outcrops are poor, and after mapping is initiated we should claim open ground, using a bulldozer to uncover outcrops, which should also suffice for some discovery work.
