TORONTO, Aug. 13, 2020 (GLOBE NEWSWIRE) -- Compass Gold Corp. (TSX-V: CVB) (Compass or the Company) is pleased to provide an update on the recently completed fieldwork at the Dialéké prospect on the Company’s Sikasso Property in southern Mali (Figure 1).
- Exploration work at Dialéké identifies two discrete >1-km-long zones of coincident gold-in-shallow-soil anomalism associated with the Siekeroli shear zone
- Pronounced gold in soil anomaly present adjacent to Dialéké workings
- Gold-bearing quartz veins recovered from shallow artisanal workings
- Drilling at Dialéké will start when ground conditions permit
Compass CEO, Larry Phillips, said, “These latest results from our Dialéké prospect have added two clear new targets to our already robust pipeline of highly prospective gold targets at Tarabala, Samagouela and Sodala. Our objective for the coming year is to confirm a gold resource at one or more of these targets contained on our Sikasso Property.”
He added, “Our technical team recently completed a review of all of our exploration results and has outlined an aggressive and cost-effective exploration program for the coming field season once ground conditions permit. The first stage of this exploration program will include a fully-funded 3,000 m drill program on our Samagouela and Tarabala prospects, where we had considerable success earlier this year. We are anxious to resume this next phase of field work as soon as the rainy season ends.”
Dialéké is located on the boundary between the Ouassada and Faraba-Coura permit areas (Figures 1 and 2). It is one of eighteen prospects previously identified along the 16-km Farabakoura Trend through regional, shallow, soil geochemistry, deep auger sampling and airborne magnetic surveys. The initial target at Dialéké was chosen based on an isolated 3.8 g/t Au shallow soil sample (the highest shallow soil on the Ouassada/Faraba-Coura permits), close to the inferred location of the Siekeroli fault, and cut by a strong NW-trending fault interpreted from airborne magnetic surveying.
The latest assay results from the Dialéké prospect were received following the Company’s recently completed field work in southern Mali, which concluded with the start of the rainy season. Samples collected there in May from spoils heaps at a new area of east-west trending artisanal workings, covering 4.5 hectares, contained mineralized quartz veins with grades up to 35.1 g/t Au (Figure 2). Follow-up Gradient IP and shallow soil surveys confirmed the Dialéké workings are centred on an area marked by numerous smaller faults and gold soil anomalism adjacent to the main Siekeroli shear zone. Another target area 800 m to the west of the Dialéké workings contains gold in soil samples up to 1.22 g/t Au. This area represents an exciting new target 2 km to the north of the focus of Compass’ field work in May 2019. This work was completed in mid-July, and the final assays were received in early August. Drilling on the prospect is planned once ground conditions permit.

Pit Reject (spoil) Samples
A total of 90 unbiased samples were collected on a 25 x 25 m grid over the newly identified workings at Dialéké. The samples were 1.5 to 2 kg and randomly collected by shovel from the waste piles adjacent to artisanal workings. Shafts vary in depth from 6 to 30 m, with the water table occurring at 24 m.
Gold concentrations ranged from 1 ppb to 35,110 ppb (35.11 g/t Au). Five samples had gold grades greater than 1 g/t Au (1.08, 2.98, 4.00, 4.63 and 35.11 g/t Au), and 18 samples had gold grades between 0.2 and 1.0 g/t Au. Inspection of the pit reject samples showed the mineralization was present in smoky quartz veins with oxidized pyrite that cut a sheared granodiorite. This is similar to the mineralization noted in other prospects on the Farabakoura Trend (e.g., Farabakoura, Kabangoue, and Boumban).

Shallow Soil Sampling
A total of 320 infill soil samples were collected on a 100 m x 100 m grid centred over the Dialéké and Farabakoura NW workings. Gold concentrations ranged from 1 ppb to 1,220 ppb (1.22 g/t Au), with an average concentration of 24 ppb. Eleven samples contained more than 100 ppb Au (0.10 g/t Au), which is considered extremely anomalous in the total shallow soil database (7,101 samples) covering the 179 sq. km Ouassada and Faraba-Coura permits.
Gold anomalism correlates closely with the presence of artisanal workings and interpreted faults. A large 1,200 m long and up to 550 m wide zone of enhanced gold anomalism parallels the western contact of the Siekorole fault and is centred on the Dialéké workings. This is considered the primary target zone.
A second area of enhanced anomalism is noted in the NW corner of the sampling grid, including one sample with 1.22 g/t Au. This 500 x 500 m zone correlates with a fault parallel to the Siekorole fault that cuts a granodiorite. Only weak anomalism is present in the vicinity of the Farabakoura NW artisanal workings, although a pit reject sample from this location contained 1.20 g/t Au.
Gradient Induced Polarization (IP) Survey
Concurrent with the geochemical sampling programs, a Gradient IP ground geophysical survey was performed over the Dialéké and Farabakoura NW workings. The survey covered an area of 1.5 sq. km (1.4 x 1.0 km) and lines were orientated in a NE direction. The resistivity and chargeability data were processed and interpreted by Jeremy S. Brett, M.Sc., P.Geo. (MPH Consulting Limited).
The processed data indicate the location of the Siekorole fault (Figure 1) and a parallel fault 600 m to the west. The Dialéké workings are located at the centre of a 700 x 700 m zone of faulting that is likely a favourable location for mineralization. The large area of gold soil anomalism in the northwest of the soil grid appears to correspond to an area of less structural complexity.
Interpretation of Field Work
Surface geochemical and geophysical surveys at Dialéké have significantly enhanced the understanding of likely locations for gold mineralization at the prospect. Two targets have been identified that require follow-up drilling: a 700 x 700 m area centred at Dialéké, and a 500 x 500 m area 400 m to the northwest of Farabakoura NW. Both targets are located on north-northwest trending faults in contact with intrusive rocks and extend for over 1 km.
Compass’s technical team recently completed a thorough review of all exploration data collected to date to appraise current and new target areas. The review outlined an aggressive exploration program for the coming field season totalling at least 3,000 m of air core drilling on previously identified broad zones of shallow gold mineralization on the Company’s Samagouela and Tarabala prospects, and ground geophysics and in-fill soil surveys on additional areas of interest. This exploration is fully-funded and is expected to start as soon as field conditions allow, likely in November.
Targets have been selected according to their potential to host shallow, open-pittable ore systems.
