FINAL REPORT

CHOLLA MTN. REPORT

CAP 142-175

The subject project has been described in previous quarterly reports.

Briefly stated, we had developed sufficient geologic data to infer the possibi-

q

lity that Conoco's Florence deposit (Poston Butte), which is a major primary

deposit grading about 0.4% Cu -- but which has negligible chalcocite enrichment --

was in the upper plate of a low-angle fault. We gathered evidence suggesting

that the original top of the deposit beneath Tertiary conglomerate or volcanics,

could have been shifted several miles to the southwest, toward a zone of min-

eralized fissures at the south end of Cholla Mountain, along a secondary low-

dipping fault within the upper plate,

We now feel that the assumption of direction of movement, which was

based on the tilt of the erosion surface carved on mineralized Oracle granite

and overlain by a layer of Yellow Peak conglomerate (equivalent to Whitetail),

thus giving us a plane of tilt and therefore, by rule of thumb, a direction of move-

!,!

ment, requires reassessment, Cross-sections in our files (only partially complete)

do indicate an abrupt drop in grade deep below the Conoco deposit at Poston

Butte which verifies, or at least tends to verify, the assumption that the flat

fault shown on their model was indeed correct.

We suspected that the porphyry dikes and stringers of sulfide mineral-

ization (evidenced by their leached boxworks) at the south end of Cholla Mtn.

represented the tail end of the zone of alteration and mineralization, and that

the low grade pervasive copper anomaly - although in some respects surely exotic,

probably derived mainly from thin veinlets such as those which may be seen

along the railroad cuts on the south and west sides of Cholla Mtn. If this

entire length is related to a single deposit, it seems abnormally long. A low-

angle fault slicing above the major copper center at Poston Butte could account,

o

we believed, for such a lengthening of the zone. This slice could well contain

the upper portion and residual leached capping and chalcocite enrichment of

substantially higher grade.

Drill hole data gathered surrounding the district indicated extensive

drilling exploration, even though we do not have information or analyses on all

of the holes. Moreover, the mineral rights were private and only one tract of

ground was obtainable at a reasonable cost. We were, thus, limited to the land

owned by Virgil Chandler, which appeared to be situated in an ideal location to

test the fault hypothesis as outlined above.

Drill hole CM-I evidently penetrated the southwestern, propylitically

altered edge of the portion of the deposit now held by Asarco, but the copper

assays were low - under I00 ppm. Drill hole CM-2, located about 3/4 mile south-

west of the first hole, entered fresh-appearing Precambrian Oracle granite, but

with surprisingly high copper geochemical analyses averaging well above I00 ppm

with a maximum of 670 ppm. Our drilling, therefore, has merely added to the

already present pattern of probably exotic copper (although transport may not

have been far distant from Originally mineralized fractures) which surrounds

Cholla Mtn. This, in turn, lies southwesterly from the southwestern tip of the

mineralization as we now believe it occurs surrounding the Asarco ground.

There is no "hard" data on the deposit held by Asarco. Information

supplied by S. Van Nort suggests the two deposits are similar, but that the

Asarco deposit is smaller -- about I/3 the tonnage of Conoco's. Early cross-

sections displayed at previous meetings, prior to our drilling, indicated a

trough between the two deposits, but placed both deposits in the same plate.

A reinterpretation shown by the cross-section in this report indicates the

Asarco deposit to be part of an upper plate strand, which was shifted from

above the Conoco deposit. The trough, known by drilling and partly located

by gravity, is now thought to be a simple graben. This interpretation is ques-

tionable, but possible; we should remember that we have no hard data on the

Asarco deposit. -2-

The geologic map here presented shows the principal features affecting

this project. The district as such has not yet been wholly abandoned, and we

are maintaining an action file which may eventually produce another concept in

this area. At this time, however, the concept as originally presented appears

doubtful, and we recommend that the option on the Chandler ground be dropped.

GRAVITY SURVEY CHOLLA MTN PROJECT

PINAL COUNTY, ARIZONA

FOR

PILLAR, LOWELL & ASSOCIATES

INTRODUCTION:

During January and February 1979 a gravity survey was per-

formed on the titled project. The field survey was under the

direction of Kem Johnson, technician| the report and inter- i pretation by Robert E. West and W. Gordon Wieduwilt, geophys-

icists for Mining Geophysical Surveys, Inc.

Reconnaissance gravity data was obtained in January followed

by detailed surveys along accessible roads in early February.

Geological data including previous drill hole results pertain-

ing to the area was discussed by John Kinnison.

SUMMARY:

A very complex area of gravity boundaries suggests a horst

and graben structure across a broad area extending from Cholla

Mtn to Florence and mainly north of the Gila River drainage.

East of Florence a deep basin characteristic is observed. A

buried ridge extending south-southeasterly from Cholla Mtn sep-

arates two deep basins which occur south of Coolidge and south-

west of Florence.

The complex horst and graben structures west of Florence

are partly supported by the location of outcrop and by known

drilling results. Minor variations in the simple Bouguer

gravity data reflect these known conditions and possibly other

buried trends. A steep regional gravity trend decreasing to

the east complicates the depth to bedrock interpretation in

this complex pediment. Assuming a 0.2 gm/cm 3 specific gravity

contrast between alluvial cover and bedrock, a number of depth

to bedrock estimates were made.

GRAVITY INTERPRETATION :

Three sets of gravity sections, A, B, and C, and one

detailed section, D, were plotted to aid in the interpretation.

These sections allow positioning of gravity boundaries on rela-

tively steep slope segments of the profiles. In section D an

E-W regional gravity gradient is assumed, and residual gravity

values wer~e used to obtain depth estimates noted on the map.

No N-S gradient is assumed in the basin area south of Coolidge.

~ , ~ ~ , . ~ . ~

From previous experlence in the Florence area, we believe a

specific gravity contrast of 0.2 gm/cm 3 best represents the average

difference between bedrock and the graben fill.

There may be difficulty in matching known low angle graben

margins to the gravity interpretation since such margins would

not be sharply defined by gravity contrast, especially if the

grabens were a relatively broad shallow feature of only 500' or

lO00' deep.

....... MINERALS COMPANY

2425 N. Huachuca Drive Tucson, Arizona 85745

. / April 5, 1984

Mr. Steven D. Van Nort ,,A / I 5115 N. Oracle Road ~V V~ Tucson, Arizona 85704 /

/ Dear Mr. Van Nort: /

Reference is made to a receny letter from Mr. Peter Na]b~ndian requesting that Exxon Minerals Company provide you with factual information from a hole that Exxon drilled in 1982 'on lands under lease from Nalbandian Farms, Inc. In compliance with this request and paragraph 13-C of the lease agreement, all factual information from the hole is enclosed. This information consists of rotary drill cutting analyses.

The single hole completed on Nalbandian lands was rotary drilled to 756 feet. The information enclosed is for drill cuttings from this interval. The bole was cored from 756 feet to its total depth of 1174 feet. Unfortunately, Exxon's objective rock type was not encountered by the coring and, therefore, no chemical a~alyses were completed for the core portion of the hole.

tn addi t ion t o the g e o c h e m i c a l informat ion enclosed, I am also sending a page-s ize map showing the approximate location of the driI1 hole.

Encts.
