VII. DESCRIPTION OF MINERALOGY
I. SULFIDE ZONE
Within the sulfide zone, the main copper minerals are primary ehaluoeite and bemire, with or without pyrite and quartz, as veins and disseminations.
Chaleopyrite is minor and apprears in the middle and lower portion of the mineral intercept and generaUy presists at depth_
Pyrite, with minor chaicopyrite, also increases with dep,/~ and i~ the outer holes.
Table 7-1. Depth Variation of M.ineral Components within the dr///holes, indicates the general distribution of chalcocit~ (¢c), bornite (bn), ohaleopyrite (up), pyrite (py), and hematite- specularite (hem). The notation ofpyrite and hematite generally suggests the hole completely penetrated the copper-bearing mineral zonation at depth.

In Table 7-1, the abundance of cc and cc-bn generally indicates intervals of plus 1% copper, wlfile ec-bn-ep intervals are below 1%, and ep indicates intervals below 0.5% copper.
This genera/trend can be not6~l in the dr///hole assay intervals of the holes located in the Addendum portion of the report.

l~igures 7-1 through 7-4 are photographs of the relationship of py-cp-bn-cc-digeni~e fi-om highex grade samples. Other photographs show bornite-oh__aleocite textures similar to that found deep at the Magma Mine~ west of the Superior East deposit, as shown in Figure 7-5, (Pla~e XXf).
2. NATIVE COPPI~P. ZONE
Native copper was found in a few holes in the oxidized upper po~ons, either in the slide blocks orthe oxidized tops above the sulfide in the in-place biocks.
The abundant native copper is the primary mineralization in the Whitetail CongIomerate basin to the west of'the in-place sulfide body.
In a report of the electron microprobe analysis of the native copper, itwas found that the average copper concentration of the samples tested was 99*/, copper and no sulfur was noted,
At the very top of the main native copper z o ~ is a sho~ interval o£ ~ _ Study of this mineral and the native eoppet suggested both were exaplaced as their respeetive mineral. No sulfides are present or involved in the euprite-native copper distdbtion in the B'aitota~ Conglomerate.
Addendum 7.1 is a File Memorandum covering testing of the Native Copper ore, The conclusions were that with removal of metallics from the flotation tailing by screening increased recovery to 90% in combined rougher flotation concentrate and screen overedze. Also when using an acid-ferric sultkte leach, the recovery was 92 % of the copper.

Subject: Further Testing of Native Copper Cr~ (~roj, 2036)
Two flotation tests ~are run on this ore to check previous flotation ¢~sts ~ Hazen lq~sea~ch. Data sheets fo~ these tests (Test Nos. NC-3 and NC-J4) are stta~hed.
The ~e ~as ~round to 55% passing 200-me~h and floated for 15 minutes. Tes~ NO-3 used Aero~romotar 208 collector and a combination of pine oil, DF ~50, and nresylic acid frothers. Test NC-4 used AP P-08 and the same frothers w~th addition of sodium hydrcsulflde and Z-6 to attempt to get stronger float condition for th~ coars~ mete,lilt copper.
Both tests ~elded about 50% recovery of the copper in rougher concen- trates as~sying 6.7-7.0% Cu.
As in previous flotation test~ the low copper recovery v~as due to failure to float th~ coarse (+6~ mesh) metallic copper ~ven with long flotation times and lar~ eollec~or Sosages. in both te~ onl~ abou~ 25% of the copper in the +65 mesh size floated.
The rougher tal/ings and concentrates w~x~e screened m~d the fractians assayed separately. Table I in the Kttacb~ m~ppor~in~ data gives total copper assays of the screen fractions and d!s~ributlons ~of copper in the products.
The +~8 ~nd @65 ~e~h fr~ctions of the rou~ tailin~s wer~ added into t2m mough~r concentrates by calculation for Tests 3 and a respectively. These results ~re ~ized in Table 2. Addition of th~ coarse metallic copper in these fraotions to ~he rougher concentrate yields copper recoveries of 88-92% in combired concentrates assaying 7.0-9.5% Cu.
Farther test work on this ore should investigate the feasibillty of coarse grindinE followed by separation of metallics either by screening through 48 m~h or tabling. Toe screen undersize o~ table railings wouJ.d then be ground finer and floated. C!eaner, flotation concentrate combined with +48 mesh ~tallics would be the final copper concentrate.
Two le~h tests were rttu on minus l~-mesh ore to determine the amenability of the Dative copper to leachln~ by anz~niac~l mmTDni~m carbonate ~nd H2804 - ferric sulfate solutlc~s.
Test NC-I used a 20 ~pl. ammonium carbonate - ~0 gpl. NH~ solution. Test N0-2 used 50 gp!. sulf~ie ~old and 15 gp~. ferric iron (added as ferric sulfate).
Both leaOhes wmr~ ~itated on bottle Tolls at 33% solid~ for approximately f o u r days. The leach pulps ~re fil~r~d and washed on the filter with 5%

VIII POTEb~I_AL FOR FUTURE DEVELOPMENT
The potential for future development includes a number of factors, These include: 1) confirmation af the mineral resource. 2) expansion of'the mineral resource, 3) potential
mining mescal% 4) inherent water and t empera t e Kactors, 5) ettvkoumental considerations, and 5) costs. The under-lying land agrccmcutS wit~ Contintal Copper Company (and their agreement with Kilb~ C~,yetl), and ASARCO, ahould be clarified and made acceptabte for long- term holding o f the property.
Figure 8-L addresses points I and 2, in the su/ffde zone. Shown are the drift hole locations (open circles) of the present drill holes, along with their rated thickness-assay grade, and shown as fallecl triangles are sites to further confirm the values within the mineral resource and to expand the l"esonr~l~_
Eleven additional drill holes are along tim present road system estabhslmd fbr the previoua and proposed, at the time, drill hoIe~. Road cn~truction would need to be completed to the rem~iMog seven sites, o~en from the present road ~ystem.
Nora t/me ~e open-t~a~g/c sup~rfmposo:f over ate open cird¢ at hole A- 17 sigt~cs the 12ale has been garted and needs to be temple.ted to the mincr.~d:zone.
The curvi-linear plots of xxxxxxxx suggest wh~t may be the main mineralized zone based on a central coreof lower grade mineralization surrounding the higher grade of plus I% copper in the
z o n e .
Drill holes Ad3 and A-15 show that substantial thickness of 0.55% and 0.71% copper mineralization is found outside the oarvi-linear plot as outlined. Indicating that further expansion is available not only within the bracketed zone but also furflmr outside.
Confirmation and expansion of the available native copper in conglomerate resource will be partially tested by the western-most ho{es shown on Figure 8- l, These two holes would ./r~cate further mineralization in the footwall (east) side of the Devils Canyon Fault in the Whitetafi Conglomerate as well as the deeper sulfide mineralization in the bedrock units, Review Figure 6-3 for a general plan showing the holes A-4 and.A-7, which have the thick sections of native copper west of the Devils Canyon Fault. Additional holes north and west of hole A-7 are recommended for testing the native copper resource mad extension.
Potential mining methods include block oaring, vertical crater r~ffeat, cemen~l cut and fill (to utilize mo~t of the waste mill produ¢~), and pcmg/ble ~n situ. In s~tu is prohabty not acpliegble in the sul/~de zone, but may be in the native copper resource,

Thus mining Conditions must take the apparent steep dip of the schistosity into consideration as the schist contains abundant miCa, and the mass is very moveable along the s~histosity layers.
Use ofa mmmi-boring machine to ramp down to the 3500-foot level from the Carlota area would ¢~bIJ~h ;~ t~etwork of mibgaratlel umaels for ~onfilmatiott and expaxmiott in ting-driiling the deposit with 1000 foot holes. Tb_is would Mso provide needed data for geo-mec&anica~ smdi~ on the-~aritm~ angie-im~c, pt~ of the se~to~ty for deterxnining the most probable mining metkod
and sequen~eing of mining blocks.
Water is probably not a prob|em in the mineral zones, as mo~t of the drill holes suggested a r?uid loss in such zones. However, within the overlying dacite unit. water-bearing intervals were noted and these may extend some distanc, along the porous zones and/or vertically along fracture-fault
. structures.
At the Magma Mine to the west., they noted an increase of water flow into the mine, especially the lirae.~owe reglacem~ttt mmittg area, a~er heav~ winter/manamr rains over the daeite plateau. Along Queen Crvvk, near the tTighway Wzme| on State Highway 60, the water was no~ed to fismael doxma into ~arge ru~orle zones i6o~g f~'att~, an~ along bedding zones within the limestone bed~. Therefore, if mining supplied fractm-es reach is03 the mgm drainage areas witM, the d~c~te, these would provide additional water ace,s into the mining zone following abundant water flow in the
drainages.
The Arizona Water Company at Superior picked up water at three points in Queen Creek ea~ of the town of Superior, for distribution to the towrt of Superior. From 196.2 thru 1970, they collected 25-30 million gnllons of water per year. The water flowed from springs and rain runoff. After Magma completed their haulage mnnd in 1971 fi-om #6 shaf~ to the new #9 s h ~ cross'rag under ~ e Queer~ Creek drainage, ~¢ stxi~gg driect ul~ and no w~.tex xao~ rum in Queett Creek except during excess/re rmtofFpeJiod$. /_n 1971, the Water Company ~rol|ected only 12.7 afiDion gallons ofwa~ex., and only "mhaor" water during 1972, even though winter and summer rain~ continued over the plateau. As stated above, investigations indicated th~ ~e water itow has no~ been transfered to the underground workings along fault structure extensions and along bedding zones within the limestone units which crop-out in Queen Creek.
Magma closed the mine at Superior in 1982 and allowed the water to fill all the workings t~om the 5000 Level on up, from west to east. Magma then decided to reopen the limestone replacement division, serviced by the #9 shaft on the plateau,, in 1989. They found the water level had risen to above the 3000 Level iu their #3 rhea.Co, wi~.x¢ they irate]led pumps for dewatering the workings. By 1990, they were ~mpm~g 2500 gallo~s per raioute ~md had d ~ w a t ~ ~he F.~t Division down to the 3400 Level. BI-tP has sin~e pareha~ed Magma C.oppe~, and r~enti~ etosexi the operations at Superior. The present East Replacement Division workings will ngdm be ~ with w~tcr. The intra-eomaeeted vein workings to the west will also be fl~ed with waker as before.
The temperatures found in various drill holes and at the Magnm Mine are listed in Table vm-1 .

The gradients have been established for the intervals listed and then used to calculate the estimated temperature (* F) at the various depths.

Exempting the holes A-3, A-4, and A-7, located west of the Devils Canyon Fault, and DCA-1A located north of the State Highway 60, the average gradient in the sulfide zone is 1.32" per 100 feet below the 3000 foot depth. Thus, at the 3000 foot level, near the top of the sulfide intercept, the temperatures expected range between 110* and 115", with an average of 112*F, while at the 5000 foot level, the average is 139"F. Working in such temperatures would necessitate the use of refrigeration cooling, such as used at Magma, where the average temperature exceeds those found at the Superior East sulfide zone.

P L A T E XAI
A.--Deep- level chalcocite (light) and bornite (dark) , Cigar-shaped bornite areas show pronounced parallelism. Between bornite "cigars" is a sub- graphic intergrowth of chalcocite and bornite. It is believed cigars are skeletal crystals of bornite which were first to form. With a decrease m iron content, remaining mater ia lz in solution separated out as I~mul- taneeus deposition of chalcoclte and bornite. 2,000-foot level, 15 x-cut . (x le0)
B. - -From same section as A. Some of larger bornite a r e a a re crossed by i r regular veinlet* of chaleocite. With further decrease in iron content, conditions were such that only chalcocite deposited. Solutions deposit- ing chalcocite had some replacing action on bornite which took form of veinleta. The~e veinleis lack continulty and regular i ty of supergene chalcocite ve/nlets and do not follow cracks and gangue boundaries. All the chalcocite Is believed to be hypo~ene. (x ~L30)

X SUMMARY ANDCONCLUSIONS
The Superior East sulfide zone has several positive attributes: 1) An above average grade of ntin~ali~a~ion in a form for b o J ~ - n ~ med~ods, 2) a reJatJvdy ele_~n bomit~chalcocite mi..-~ralc~g:y with eb, alcopyfite in the low~ levels, and 3) an open-eyed ¢xm!Rgurafio~ for expansion possibilities of the mntmgc ~ d grade.
The negat/ve t~ctors iac/ude the depth to the zone, the higher temperautres, and the amouat of schist which is unstable in most workings. The under-lying agreement terms are onerous.
The native copper zone to the west is also attractive for its simple metallurgy and the probable extent of the mineralization. The negative factors is primarily the depth, potential water problems, and the land situation.
In conclusion, the property is one that holds promise in the Future. as the large open-pit mines become deple~texl in the first quarter o£the 21st cetttu~. HRvittg fftc tonn~rade now ~ e d and the extention probab~tieS. ~e~ two deposits may provide ~e fl~gship for a ~ubstantial enterprise.
