Gold And Copper Exploration In Jamaica

- Gold And Copper Exploration In Jamaica
Guillermo Salazar S., President of OroGrande Resources Inc., announces that the Bellas Gate concessions were acquired by OroGrande Resources Inc. ("ORG") in 1991 and are comprised of three contiguous exploration licences covering an area of 42.4 square miles. Situated approximately 40 miles northwest of Kingston, our claims protect a large part of the Central Inlier, an area of Cretaceous volcanic and sedimentary rocks, within which the Island's historical copper mining started in the 1850's.
Geologically, the island of Jamaica is part of the tectonically active Greater Antilles Island Arc environment. The large Pueblo Viejo epithermal gold district (historical production of over 600 tonnes of gold) in the Dominican Republic and the recent discoveries in Cuba, all part of this Island Arc, confirm the area's potential.
In 1988, a CIDA-sponsored stream sediment program defined nine priority ONE anomalies for gold and copper in ORG's Bellas Gate concessions and confirmed a close relationship between copper and gold. BHP-Utah, following up on this work, staked on the Main Ridge gold deposit, also a priority ONE anomaly, located about ten miles west of our Bellas Gate concessions. This deposit is going into production under the auspices of Orvana Minerals Corp. and a private group of investors. Although at least 32 copper and gold showings have been identified on the Company's concessions, previous ORG work was concentrated on the Connors and Camel Hill prospects.
Preliminary drill testing of the Camel Hill prospect, a copper- in-soils anomaly within the Southern Alteration Zone ("SAZ") that is a least four times larger than the Connors prospect, encountered the following results:
DDH From To Core Length Gold Copper ft. ft. ft. oz/ton %
CAM 92-1 40 770 730. 0.006 0.48 including 40 445 415. 0.006 0.63
CAM 92-2 0 585 585. 0.006 0.46
CAM 92-3 10 230 220. 0.004 0.36
CAM 92-5 11 505 494. 0.007 0.43 including 170 290 120. 0.010 0.63
Drilling in 1957 found significantly copper mineralization at the Connors prospect, with one drill hole reporting an intersection of 184 ft. of 1.51% copper but no gold values were reported. Despite these encouraging results, this area was not drilled again until 1991, when Golden Ring Resources, a Vancouver based Company, optioned the property from Trev Corp. (now ORG) and drilled a well defined soil anomaly about 500 ft by 400 ft with copper values greater than 200ppm and gold values greater than 50 ppb. The more significant drill results from the Connors deposit area: DDH From To Core Length Gold Copper ft. ft. ft. oz/ton %
92-1 surface 470. 470. 0.013 0.53
92-2 45 365 320. 0.011 0.69 including 210 330 120. 0.018 0.86
92-3 45 365 320. 0.005 0.46
C-4 70 254 184. NA 0.91
CON-4 69 362 293. 0.014 0.69
Both of these deposits require further drill-testing. The Connors deposit is open at least to the south and west while the Camel Hill deposit is open in all directions.
While the results from both areas are encouraging, it is evident that much more work is required to further develop economic reserves. However, there is every reason to believe that other prospects - when combined with these two areas - a very significant tonnage could be developed. ORG's review of in-house data has identified several other areas on the concession that require further work.
GOLD MINE - MAB HILL AREA
Our review of the available data shows that a belt of epithermal gold-copper deposits (Gold Mine, Charing Cross, Congo Hill, Stamford Hill, Mab Hill, GEO Hill, etc.) occurs immediately to the west of the known Camel Hill deposit. This belt extends northwesterly, is subparallel to the SAZ and is defined by a +3 km long +200ppm copper soil geochemical anomaly. Our Bellas Gate concessions also protects the Stamford Hill mine from which 200,000 tons grading 5% copper were extracted by the Clarendon Consolidated Mining Company from a vein system reported to be 20 feet wide and continuous from surface to at least 480 feet of depth. At Charing Cross, another showing on this newly recognized belt, 24 surface samples taken at ten foot intervals averaged 9.16% copper and 0.22 oz gold/ton over 1.5 feet.
LUCKY VALLEY - SIMON AREA
While this was also defined by the CIDA program as a priority ONE anomaly, follow up work in this area has just begun. In 1994 - 1995, initial prospecting in the Lucky Valley area identified a significant copper anomaly covering an area of about 1,000 ft. by 1,200 ft. Stream sediment sampling gave values of 243 ppm copper while chip samples from this area ranged up to 7.62% copper and averaged 2.44% copper at the Diamond (western) area while very old, unsampled trenches have been noted in the Simon (eastern) area.
OLD WOMAN HILL AREA
The Old Woman Hill area is ranked as the highest of the interpreted target areas based on CIDA's 1988 survey. Initial sampling in 1991 indicated a strong gold anomaly (up to 1690 ppb in heavy mineral concentrates). Nine samples from this area collected in 1994 averaged 3.84% copper and gave gold values up to 0.265 oz/ton. Stream sediments ranged up to 795 ppb.
OTHER TARGETS
Work by BHP-Utah in the Brown's Hall area identified a new intrusive belt to the east of the Connors or Northern Alteration Zone ("NAZ") with associated trace amounts of copper and a strong potassium alteration.
FUTURE PLANS
The Company is presently awaiting results from work carried out at the Gold Mine-Mab Hill and Lucky Valley-Simon areas, where a total of 600 soil and 300 rock samples were collected in November of 1996. Preliminary assay results show several rock samples with high gold values (up to 3,220 ppb's) as well as numerous copper values in the 0.3% to +1.0% range. Results will be published soon after the reports are available. We expect this work to define drillable targets for testing in 1997.

Gold Copper Bellas Gate, Jamaica Property
OROGRANDE RESOURCES INC ("ORG-Y;ORGDF-L")
- Gold-Copper Bellas Gate, Jamaica Property
Guillermo Salazar, President reports that preliminary assay results have been received by OroGrande from 600 soil samples collected from the Gold Mine Area, Bellas Gate Project (Jamaica). The company owns 100% of these 42.4 square mile mineral concessions.
The results (map available from company), define an anomaly that is 800 meters long by 300 meters wide, is elongated in a north-northwesterly direction and is open to the northwest. The center of the anomaly is defined by 41 samples assaying greater than 1,000 ppm copper, being a core of ten samples with values greater than 2,750 ppm copper (and as high as 8,500 ppm copper) and a coincident +100 ppb gold anomaly. The +1,000 ppm copper contour defines an area that is approximately 300 meters in diameter.
The survey was carried out over an area exposed by the access road into the Gold Mine area which showed a quartz-carbonate (ankerite ?) layer overlying pyritiferous granodiorite that were cut by quartz stockworks and veinlets.
The Gold Mine area is located immediately to the west of the Camel Hill alteration belt and appears to be along a previously recognized soil copper anomaly that includes the Stamford Mine (reported production of about 200,000 tons grading 5% copper) about 2.0 km to the east of the Gold Mine area and also within the OroGrande's property.
Once final reports are in, the Company will carry out a trenching confirmation program and drilling of this target.
