TORONTO, ON / ACCESSWIRE / August 17, 2021 / Roscan Gold Corporation (“Roscan” or the “Company”) (TSX-V:ROS); (FSE:2OJ); (OTC:RCGCF) is pleased to announce positive results (Figure 1) from an additional 17 DD and RC holes totaling 2,956 meters (m) at our Southern Mankouke Zone (MS1 and MS3).

These results continue to confirm that mineralization is open at depth in fresh rock at MS1 with a broader zone. In addition, drilling at MS3 continues to expand the footprint to a mineralization envelope size that is now at 300m E-W, 200m N-S, and 10 to 40m width. More importantly, it appears that a consistent high-grade zone has been traced to a vertical depth of 120m, ended in fresh rock and remains open.

Drilling Highlights:

Mankouke Discovery Zone (MS3)

  • 3.53 gpt gold over 17m from drill hole RCMAN21-55 from 121m
  • 4.06 gpt gold over 5m from drill hole RCMAN21-51 from 67m
    • and 2.79 gpt gold over 11m from 73m
  • 4.43 gpt gold over 5m from drill hole RCMAN21-48 from 42m

Mankouke Discovery Zone (MS1)

  • 3.31 gpt gold over 16m from drill hole DDMAN21-116 from 258.4m
    • Including 11.97 gpt gold over 3m from 260.4m
    • and 1.48 gpt gold over 12m from 284.4m
  • 11.03 gpt gold over 3m from drill hole DDMAN21-114 from 126.5m
    • and 3.21 gpt gold over 5m from 155.5m
  • 3.43 gpt gold over 9m from drill hole DDMAN21-112 from 141.5m
    • Including 5.84 gpt gold over 4m from 141.5m

Mankouke Discovery Zone (MS3) - Potential High-Grade Extension at Depth to the East

At MS3, the mineralization is close to surface and commences in the saprolite. The gold envelope shows a folded shape with dimensions of 300 m E-W, 200 m N-S, and 10 to 40m width.

The mineralization is open to the West, North, and East, while toward the South, it could be seen as an extension of MS1 displaced by a fault. The East fold limp displays a good consistency with significant high-grade intercepts (DDMan20-59 with 20m @ 3gpt, RCMan21-22B with 17m @ 3.3 gpt and RCMan21-55 with 17m @ 3.53 gpt). There is also a felsic intrusive occurrence that can be traced to a depth of 200m vertical. We note that this unit can also be mineralized as it evidenced at MS1 and has yet to be fully tested in MS3.

Main Mankouke South Zone (MS1) - Mineralization Continues to Open at Depth

At MS1, the last diamond drill holes continue to show good continuity at depth and laterally in the sulfide fresh rock. Drill Hole DDMAN21-116 with 16m @ 3.31 gpt, located 100m North from DDMAN21-104B (with 25m @ 2.02 gpt - see July 6th, 2021 Press Release), shows the wide broadening of the sulphide at depth at consistent high grade, which remains open and has yet to be tested.

The mineralization is strongly associated with the alteration mainly albite-carbonate-silicification, pyrite-arsenopyrite assemblage and often with the occurrences of quartz veins and veinlets network but also fractured rock.

The mineralization envelope fits very well in the alteration halo wireframe. These diamond holes also show that the felsic intrusion played an important role during the mineralization by hydrothermal gold mobilization or remobilization. Gold is in the sedimentary package at the top and limited by the footwall, which is carbonaceous bedded mudstone, in discordance with the gold-bearing folded clastic-limestone sequence.

The gold mineralization is open at depth and laterally, following the felsic intrusive toward the North and the South which fortunately crosses the barren footwall, allowing the mineralization to extend deeper.

Nana Sangmuah, President and CEO, stated,

“We continue to be very excited as the mineralization of our Mankouke South flagship continues to expand, now with the doubling of the MS3 footprint, which remains open to the West-East and at depth.

At MS1, we are also very pleased by the broadening of the sulphide zone at depth with consistent high-grade intercepts, pointing to the feeder zone opening up at depth.

We expect a busy 2nd half of 2021 with a further 20,000m of assays to come from our Mankouke West, Mankouke South, Mankouke Centre, Kabaya KB4, Dabia South and Moussala MOU1 targets in addition to delivering our maiden resource estimate by year end”.

Geology

The gold mineralization at Mankouke South is located approximately 25km east of the Fekola mine (B2Gold Corp.), but also along a prospective major NE-SW structural corridor from Siribaya-Diaka (IAMGOLD Corporation) to Seko (Oklo Resources Limited). Gold mineralization in Mankouke South occurs within hydrothermally altered and sheared metasediments of the Kofi formation which include greywacke, limestone and diamictite but also in the edge of a felsic intrusive cross cutting the sedimentary package.

The Mankouke South mineralization is located within the sheared eastern limb of a fold directly above a footwall unit of finely banded and alternating graphitic shale and limestone referred to as the dirty carbonaceous mudstone. The border north of the mineralization corresponds with the edge of a NE-SW conductive zone from the geophysics surveys but MS3 also overlays the beginning of a Nord East conductive lineament. The gold mineralization is associated with a strong alteration over several lithologies, mainly albite, silicification, ankerite and chlorite, with the sulfite occurrences (pyrite, arsenopyrite) but also fracturing and quartz veins and veinlets.

Drilling Contract and Analytical Protocol

Roscan uses Air Core (AC), Reverse Circulation (RC) and Diamond (DDH) types of drilling in the Kandiole Projects. The Air Core drilling is mainly applied to drill early exploration targets.

The samples are sent for preparation to the Bureau Veritas Mineral Laboratories in Bamako, Mali and assayed at their analytical facilities for fire assay with atomic absorption finish and by gravimetric finish for grades above 10gpt Au.
