TORONTO, May 14, 2020 (GLOBE NEWSWIRE) -- Compass Gold Corp. (TSX-V: CVB) (Compass or the Company) is pleased to provide an update on the recently completed drilling at the Samagouela prospect, located on the Company’s Sikasso Property in Southern Mali.
- Air core (AC) drilling at Samaguela (26 RC holes, 1,497 m) intersected gold mineralization at both ends of a 1.4 km interpreted fault zone
- Best interval was 10 m at 1.67 g/t Au (from 50 m), including 1 m @ 13.04 g/t Au (from 50m), with mineralization open at the base of the hole
- Drilling encountered gold mineralization 1.4 km south of the Samagouela artisanal workings, including 5 m at 1.93 g/t Au (from 53 m), with mineralization open at the base of the hole
- Shallow soil anomalism (with samples up to 4.03 g/t Au) present along interpreted fault
Compass CEO, Larry Phillips, said, “Our initial bedrock drilling at Samagouela has identified gold mineralization associated with quartz veins adjacent to a large fault, and underlying extensive artisanal workings. Artisanal miners there have reported that they have used mechanical excavators to recover ‘significant’ amounts of gold. Our drilling along the same fault also intercepted gold mineralization 1.4 km to the south of the workings. The presence of anomalism up to 4.03 g/t gold in shallow soils samples is also highly encouraging for more bedrock gold mineralization.”
“These results are further confirmation that our permit areas have the potential to host several large, near surface, mineralized zones, which was our core objective for this year’s exploration program. Based on these promising findings, we plan an additional 950 m of AC drilling at Samagouela next month, starting right after we finish the second round at our Tarabala prospect.”
Samagouela Air Core Drilling Results
Between April 9th and 17th, the Company completed 1,497 m of air core (AC) drilling over selected geophysical and geochemical targets on the northern portion of the Kourou permit (Figure 1). The drilling targeted a 1.5-km-long and 200-m-wide zone identified from ground geophysics, soil anomalism and the presence of artisanal workings. The workings cover an area of 200 m x 100 m, and depths up to 22.5 m. Artisanal miners reported in late 2018 that mechanical excavation of one area of the workings had recovered 645 oz (20 kg) of gold over a three-month period
A second area, approximately 1.4 km south of the Samagouela workings, was also investigated. The primary target there was the interpreted offset of the north-south trending Samagouela fault and a large NE-SW oriented fault. This second fault is coincident with unnamed artisanal workings 2 km along strike and a broad gold in shallow soil anomaly at Ourou Ourou (Figure 1).

The Samagouela prospect was drilled by three fences of AC holes (Figure 2). The northern 12-hole fence (KOAC01-14, totalling 746 m) was designed to test the generally north-south trending interpreted fault. Gold mineralization was encountered in drill holes KOAC04 and KOAC013 (Table 1). KOAC04 contained an intercept of 5 m @ 1.33 g/t Au (from 49 m) and terminated in mineralization. A broader and higher-grade zone of 10 m @ 1.67 g/t Au (from 50 m) was present in KOAC13, and included an interval of 1 m @ 13.04 g/t Au (from 50 m). This hole also terminated in mineralization, and was targeted to intercept the known mineralization in the deepest part of the artisanal workings.
Drill targets were based on the interpretation of recently completed gradient induced polarization (IP) geophysics that identified subsurface features, and infill shallow soil geochemistry that identified areas of gold anomalism. Indications are that this at least 10 m-wide mineralized zone is related to a NNE-trending splay on the main Samagouela fault. The highest gold content of a soil sample in the immediate area was 4.02 g/t Au (Figure 2), and it was not associated with artisanal gold workings.
Mineralization was present within metasediments (metamorphosed siltstones). All the holes had a planned depth of 70 m, but due to the hardness of the bedrock, the average penetration was 53 m and the maximum depth reached was 68 m. As a result, some gaps are present between drill holes, including a 25 m zone within the area of intense artisanal mining activity.

As noted, additional drilling was carried out 1.4 km to the south of the main artisanal pit at Samagouela. Two east-west trending fences, 100 m apart, were completed, including 13 drill holes (KOAC15-26) totalling 751 m. The purpose of the drilling was to target the intersection of the north-south Samagouela fault with two other faults, a pronounced NE-trending fault and weaker NW-trending one. Weak to moderate gold shallow soil anomalism is present in the area, although one sample collected contained 0.89 g/t Au.
Two holes, KOAC15 and KOAC25, contained mineralized intervals greater than 0.2 g/t Au (Table 1). KOAC15 encountered 5 m @ 1.93 g/t Au (from 53 m) at the base of the hole, and the mineralization remains open at depth. KOAC25 contained several mineralized intervals, including 1 m @ 1.99 g/t Au (from 41 m) and a wide, low-grade mineralization interval at the end of the hole with 12 m @ 0.18 g/t Au (from 54 m). The highest-grade interval within the larger intercept was 1 m @ 0.52 g/t Au.
The Samagouela fence (KOAC01-12, and 14) was drilled on an azimuth of 160° (towards the SSE), at a dip of 60°, with lengths varying from 39 m to 60 m. Drill hole KOAC13 was drilled on an azimuth of 270° (towards the west). This fence was planned to intercept the northern part of the interpreted Samagouela fault, and the site of the reportedly high-grade gold veins recovered by artisanal workers. The two southern fences, KOAC15-20 and KOAC21-26, were drilled on an azimuth of 270° (towards the west), at dips of 60°, with lengths varying from 44 m to 67 m. These fences were drilled on an area covered by a gradient IP geophysical survey that was interpreted to cover a later NE-trending fault that had offset the main north-trending Samagouela fault. The closest artisanal workings to the area drilled were located 350 m to the north.
A 19-hole, 950 m follow-up AC drill program is planned at Samagouela based on the initial drilling and interpretation of the ground geophysics. This program is part of at least 2,500 m of AC drilling that will take place over the next four to six weeks on the Tarabala, Sodala and Samagouela prospects. The Company’s technical team is also performing in-fill shallow soil geochemistry sampling and gradient IP geophysical surveys on high-priority targets identified by previous fieldwork.
