Roscan Gold Drills 6.15gpt over 46.5m, Intersects Fresh Rock and Confirms Northern Extension of the Southern Mankouke Mineralization Trend

Toronto, August 12, 2020 - RosCan Gold Corp. (TSXV: ROS) (FSE: 2OJ) (OTC PINK: RCGCF) ("Roscan" or the "Company") is pleased to announce positive diamond drill results (Figure 1) from an additional 20 holes totaling 3,788 meters (m) at its Mankouke South Target. DDMan-20-54 (Figure 1 and Figure 3) intersected 6.15 gpt over 46.5m from 118.5m, which has increased the width of the mineralized zone to 125m. Hole DDMan-20-61 intersected 2.76 gpt over 6m including 9.55 gpt over 1m in Fresh Rock and increases vertical depth of mineralization to 173m (Figure 3).

The Government Aeromagnetic Survey (SYSMIN), which covers both the Kandiole Project area (Figure 4) and the area of hole DDMan-20-59, indicates that the Southern Mankouke Mineralized Trend is faulted off to the West, and the continuation of the Northern Mineralization Trend is shown by DDMan-20-59.

• 2.80 gpt gold over 12.0m from drill hole ACMan20-660 from 34.0m;
• 1.79 gpt gold over 20.0m from drill hole ACMan20-663 from 30.0m (End of Hole);
• 1.62 gpt gold over 12.0m from drill hole ACMan20-665 from 38.0m; (End of Hole).

Notes: 1: True width yet to be determined, 2: Table 1 - Assay Highlights, 3: 0.5gpt used as cut-off with 4m internal dilution for drill holes at Mankouke South, and 2m internal dilution for regional drill holes, 4: No top-cut.

AC regional fence drilling tests termite mound anomalies. In the event that significant results are returned, first follow-up is generally more AC fence drilling along strike and if mineralization of significant grade is confirmed over a significant strike distance, follow-up is done with RC and / or DD drilling. These 314 AC holes aided us to establish 200m strike length at northern extension to date.

Nana Sangmuah, President and CEO, stated, "These positive results demonstrate the extension of the Southern Mankouke mineralization to the North, based on the offset which the Geophysics identified in Figure 4. We have traced this new zone over 200 meters in strike length and continue to increase the foot print of the deposit. We are very excited to intersect gold in the fresh rock again and increase the depth of mineralization at Mankouke South. We remain focused on testing the full potential of our tenement package in order to yield more discoveries and expand on Mankouke South (Figure 2). Drilling in 2020 should unlock the potential of our highly prospective land package leading to more news flow in the coming weeks."

• Drill hole DDMan-20-54 intersected one of the highest gram meters to date at Southern Mankouke. This drill hole, when coupled with previously high-grade drill holes, shows the persistent high grade nature of the deposit.

• Drill hole DDMan-20-61 indicates a westerly dip of the mineralized zone, intersected the fresh rock and increased the vertical depth of the mineralization. This hole identifies the potential of the deposit to the west and we will continue to drill to clearly understand the extents.

• DDMan-20-59 confirms the offset to the northwest whereby the mineralization picks up again on the northern portion. Also, the rock texture north of the offset is similar to that of southern portion of Mankouke South.

The gold mineralization at Mankouke South is associated with quartz veining (Figure 5 and Figure 6) and/or disseminated and stringer pyrite hosted in brecciated, silicified and locally sheared greywackes and mudstones underlain by interbedded limestones and mudstones of the Kofi Formation. Mankouke South is located approximately 25km east of the Fekola mine (B2Gold Corp.).

Drilling Contract and Analytical Protocol

The drilling contracts were awarded to 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.

All diamond drill samples are sent for preparation to Bureau Veritas Mineral Laboratories in Bamako, Mali and transported by Bureau Veritas to their analytical facility in Abidjan, Ivory Coast for fire assay with atomic absorption finish and by gravimetric finish for grades above 10gpt Au. Most the AC drilling was sent to SGS. Roscan applied industry-standard QA/QC procedures to the program. Certified reference materials, blanks and field duplicates are inserted at appropriate intervals.
