Compass Intercepts Intermittent Gold Mineralization Over 1.6 km at Massala West






Results Pending from Two Other Prospects; Drilling Program Continues



Compass Gold Corp. (TSX-V: CVB) reports 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 (Figure 2).




  • Wide-spaced drilling at Massala West confirms gold mineralization along a new 1.6 km section of the Tarabala Fault
    • Highest-grade drill interval was 2 m @ 13.06 g/t Au (from 16 m; SAAC204)
    • Widest mineralized zone was 21 m @ 0.86 g/t Au (from 1 m; SAAC189)
  • Preparations are underway for an additional 1,600 m of air core drilling over a distance of 1.4 km to the north of the new zone, and 1,200 m of infill drilling on the recently discovered mineralization
  • 1,400 m of air core (AC) drilling is also planned at the new Tarabala South target
  • Drilling at Sodala intercepted intermittent shallow gold mineralization, associated with a north-south trending shear zone and strong shallow gold in soil anomalies
    • Highest-grade drill interval: 1 m @ 4.57 g/t Au (from 21 m).
  • Drilling at the Massala Main, Orange Grove, and Assama artisanal workings did not intercept significant mineralization
  • Results are pending from the Dialéké and Old Sam prospects


Compass CEO, Larry Phillips, said, “These latest results of our systematic ongoing evaluation of our extensive ground package have revealed yet another promising large, shallow gold target. Drilling at our Massala West prospect has confirmed the continuation of gold mineralization over a distance of 4.2 km, and the structure remains open at either end. We are preparing drill pads to test the strike extension of the structure, and to test the continuity with infill drilling on the best mineralized zones. This 82-hole drilling program should be completed, and the results returned, before the rainy season is heaviest in July.”


He added, “Drilling at the nearby Sodala prospect has also confirmed the presence of gold and we will conduct follow-up work later looking for wider, higher grade zones of mineralization there as well. Meanwhile, in addition to the follow-up drilling at Massala West, we are eagerly awaiting the assay results from 70-holes drilled on two promising new targets on the Kourou and Faraba-Coura permits.”


Massala West Drilling Results


Following up on the previously reported results from Massala West (see Compass news release dated March 16, 2021), Compass has completed thirty-two (32) additional shallow air core 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 (Table 1).

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.

Next Steps


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 (Figure 2). 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.

Additional results:


Massala Main and Orange Grove Drilling Results


Ten shallow AC holes (1,084 m) were drilled at Massala Main (Figure 1) 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 (Figure 1). 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.


Assama Drilling Results


Twenty-four shallow air core (AC) holes (1,236 m) were drilled at Assama (Figure 2) 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.


Sodala Drilling Results


Twenty shallow AC holes (1,084 m) were drilled at Sodala (Figure 1) 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.


Technical Details


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.
