Roscan Gold Intersects 7.52gpt over 19m including 21.28gpt over 5m at the Recently Discovered High-Grade Zone 150m West of Mankouke South

Mankouke Discovery Zone (MS2)

DDMan21-93 intersected 7.52gpt over 19m from 24.6m (Figure 2) including 21.28gpt over 5m at the recently discovered Mankouke South Discovery Zone (MS2 - March 8, 2021. 4.78 gpt over 24 m in DDH 89) which lies 150m West of the Main Mankouke South Zone (MS1). This new zone is open along strike and at depth. This hole, coupled with RCMAN21-17 (Table 1) which intersected 1.63 gpt gold over 19 m, expands the strike length of the new zone (MS2) to 100 meters and not only remains open but identifies the potential to expand the resource footprint to the north west and connect to our recently acquired Mankouke West land package. The recently discovered area lies directly on trend to the strong geo-magnetic signature that connects Mankouke West, our KN1 discovery area and Kabaya, further to the NE (Figure 4).

Main Mankouke South Zone (MS1)

This recent drilling at Southern Mankouke Zone shows the constant drill success rate with holes DDMan21-91/92 and DDMan21-94 to DDMan21-97 all intersecting gold mineralization (Table 1). The Main Mankouke Zone (MS1) continues to show strong continuity of mineralization with Holes 91 and 94 intersecting over 40m of mineralization respectively over multiple intervals (Table 1) and remains open along strike and depth (Figure 2). DDMan21-89 (Table 1) increased the vertical depth at Main Mankouke South Zone (MS1) of gold mineralization from currently 220m to 300m in Fresh Rock (Figure 3).

Nana Sangmuah, President and CEO, stated, "These are exciting times for Roscan, as we continue to expand upon our recent discovery zone (MS2) proximal to our Main Mankouke South Zone (MS1) which introduces another layer for potential resource growth. Hole 93 confirms our hypothesis for the potential of another high-grade zone, which runs parallel to the Main Mankouke South Zone (MS1). The recently discovered area (MS2) lies directly on trend to the strong geo-magnetic signature of Mankouke West, our KN1 discovery and Kabaya, further to the NE (Figure 4). One of our top priorities in 2021 will be testing for additional mineralization along this trend.

Equally compelling is the continuity of gold mineralization we are seeing at the Main Southern Mankouke Zone (MS1), with holes 91 and 94 intersecting over 40m each of mineralization. Also, at MS1 we now significantly increased the vertical depth into mineralization and fresh rock to 300m really signals we getting to a deep feeder source. The 6 recent distinct discoveries made in the last 15 months (Southern Mankouke, Kabaya, Kandiole North, Moussala, Wallia and MS2), highlights the strong prospectivity of our ground. The recently concluded financing of $15 million dollars, will allow for a robust 2021 drilling campaign which would lead to significant news flow in the coming weeks and months ahead."

Geology

The gold mineralization at Mankouke South is located approximately 25km east of the Fekola mine (B2Gold Corp.). Gold mineralization in Mankouke South occurs within hydrothermally altered and sheared metasediments of the Kofi formation which include greywacke, limestone and diamictite.

The Mankouke South deposit is located within the sheared eastern limb of a fold within hydrothermally altered greywacke-diamictite-carbonate rocks directly above a footwall unit of finely banded and alternating graphitic shale and limestone referred to as the dirty limestone ("DLS"). The Mankouke South mineralization clearly occurs in the rock package above the DLS and has been enriched, upgraded, and concentrated by subsequent folding and shearing of the fold limbs.

• The recent drilling will allow for extensions for both the new discovery zone (MS2) and the Main Mankouke South Zone (MS1) as we enlarge the current potential resource footprint. Both this new discovery (MS2) and Mankouke South (MS1) remain open. The new discovery (MS2) appears to be extending to Mankouke West and linked to deep saprolite targets currently being drilled at Mankouke West.

• Currently two (2) diamond drilling rigs are operating in the area to further expand upon this new discovery zone (MS2) and expand the Main Mankouke South (MS1) footprint. Hitting new verticals depth to 300m from 220m in fresh rock indicates a deeper source.

Drilling Contract and Analytical Protocol

The drilling contracts were awarded to Foraco, Target Drilling SARL and Geodrill who both employ multi-purpose (AC/RC/DD) rig and AC rigs at the Kandiole Project. The AC drilling is mainly focused on drilling exploration targets. Roscan applied industry-standard QA/QC procedures to the program. Certified reference materials, blanks and duplicates are inserted at appropriate intervals.

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