Compass Gold Corp. Reports Results of the Latest Drilling at the Massala West, Massala Main, Orange Grove, Assama and Sodala Prospects
Compass Gold Corp. (Compass or the Company) reported the results of the latest drilling at the Massala West, Massala Main, Orange Grove, Assama and Sodala prospects, located on the Company's Sikasso Property in Southern Mali. Following up on the previously reported results from Massala West, Compass has completed thirty-two (32) additional shallow air core (AC) holes (1,914 m) at this prospect (Figure 1) to test for the presence of gold mineralization associated with the Tarabala fault over a distance of 1.8 km. This drilling included nine fences spaced at 200 m intervals, with significant gold intercepts present on six of the fences. The widest mineralized interval was encountered in SAAC189, with 21 m @ 0.86 g/t Au (from 1 m) including 6 m @ 1.67 g/t Au (from 1 m), 4 m @ 1.14 g/t Au (from 10 m) and 4 m @ 0.74 g/t Au (from 18 m). This hole was located 225 m south of the discovery hole SAAC123, which contained 24 m @ 2.35 g/t Au. The highest-grade interval was located in SAAC204, 1.3 km to the south of the discovery hole (SAAC123), and contained 2 m @ 13.06 g/t Au (from 16 m). Each four-hole fence contained at least one mineralized hole that comprised several mineralized intervals. The intervals varied from 1 to 6 m, with individual intervals varying from 0.20 to 22.6 g/t Au. Based on the highly encouraging initial AC drilling results at Massala West, Compass will drill 22 more holes in several 200 m spaced fences, over a distance of 1.6 km to the north along the target structure to test its strike potential. An additional 22-holes (1,100 m) will be drilled as infill around the holes reported in this release. Based on the positive AC drilling results at Massala West, and interpretation of recent Gradient Induced Polarization (IP) geophysics, a total of 82 AC holes (totalling 4,100 m) are planned for the Tarabala Trend (Figure 2). These include 54 holes (2,700 m) on the Tarabala fault at Massala West, and 28 holes (1,400 m) at a new target located immediately south of the Tarabala prospect. Drilling pad preparation is underway, and it is anticipated that drilling will be completed prior to the heaviest part of the rainy season. In addition to the AC drilling, sites have also been selected for deeper reverse circulation (RC) drilling at Tarabala (2,500 m), and tentatively selected at Massala West (2,500 m). Several diamond core holes (500 m) are also proposed at Tarabala and Massala West. The purpose of this drilling will be to test the down dip extension and continuity of mineralization to depths up to 120 m from surface. Preparation of the drilling pads will take place in June, and will allow drilling during the rainy season. Assay results are pending from 1,412 m of AC drilling at the Dialéké prospect (Faraba-Coura permit), and 889 m of drilling at the Old Sam prospect (Kourou permit). Ongoing in-fill shallow soil sampling and ground geophysics are continuing on other parts of the Sikasso property, and Compass's technical team is continually appraising and identifying new targets. Ten shallow AC holes (1,084 m) were drilled at Massala Main to test a small area of north-south trending artisanal gold workings. Only one hole (SAAC173) intercepted gold mineralization, 3 m @ 0.92 g/t Au (from 24 m), including 1 m @ 2.01 g/t Au (from 24). The mineralization occurs on the interpreted Massala fault, and correlates with a mineralized zone (3 m @ 1.90 g/t Au) previously identified by drilling 1.5 km to the south at the Massala East prospect. No additional work is planned at the Massala Main prospect. A total of 8 holes (480 m) were drilled on two 200-m spaced fences at the Orange Grove prospect. The prospect is 3.6 km south of the Massala Main prospect on the Massala fault, and is located 1 km east of the Tarabala fault. The target was chosen based on interpretation of ground geophysics and the presence of a shallow soil sample containing 5 g/t Au. Only one hole (SAAC212) intercepted mineralization (1 m @ 0.46 g/t Au). Additional drilling might be required in the future to identify the source of gold indicated from the anomalous soil sample. Twenty-four shallow air core (AC) holes (1,236 m) were drilled at Assama to test a 250 m by 120 m area of surface gold excavations at the southernmost part of the Tarabala Trend. A 13-hole fence was drilled over the artisanal workings and a second 11-hole fence 200 m to the north. These holes were also designed to target two of six NNE-trending faults, understood to be part of the Tarabala shear zone as interpreted from Gradient IP geophysics. Drilling identified the quartz veining associated with the projected fault structures, with only trace amounts of gold mineralization (<0.22 g/t Au). Select geochemical tests (cyanide leach) are being performed on the drilling samples from the Tarabala Trend to determine the total gold concentration of samples. Twenty shallow AC holes (1,084 m) were drilled at Sodala to test an area 350 m east of the currently active shallow gold workings. Two 10-hole NW-trending fences were drilled within a 500 m by 500 m area marked by extremely anomalous shallow soil samples (e.g., 31.3, 10.1, 2.5, 1.29 g/t Au). Geological mapping and interpretation of Gradient IP geophysics identified several north- and northeast-trending faults on each fence that were coincident with the soil anomalism. The drilling results confirmed that the N- and NE-trending faults likely control mineralization as the highest gold intercepts were recorded at the predicted locations. The best intercepts were 1 m @ 4.57 g/t Au (from 21 m, SEAC009) and 1 m @ 1.45 g/t Au (from 17 m, SEAC014), both associated with N-trend faults. Most of the mineralized intervals were less than 2 m and less than 0.5 g/t Au. It is likely that weathering of the narrow, high-grade mineralization is responsible for the exceptionally high-grade shallow soil samples documented from the area. Follow-up work is recommended on the gold-bearing structures to determine if wider zones of mineralization are present along strike or down dip. Air core holes from Massala West, Massala Main, Orange Grove, Assama reported here were drilled on an azimuth of 270° (towards the west), at dips of 55°, with the exception of two holes at Massala West, which were drilled at 090° (towards the east). AC holes from Sodala were drilled on an azimuth of 315° (towards the NW). Hole lengths at both prospects varied from 50 to 60 m. The drill fences were designed to test structures interpreted from Gradient IP surveying, and potential mineralized trends identified by Compass's earlier fieldwork. Drilling was performed by Etasi and Co. Drilling (Mali). All samples were prepared by Compass staff and an appropriate number of standards, duplicates and blanks were submitted and analysed for gold at SGS (Bamako, Mali) by fire assay.
