Roscan Gold Increases Vertical Depth to 155m, Intersects 4.84gpt over 62m, and 4.76gpt over 46m at Mankouke South

Toronto, May 4, 2020 - RosCan Gold Corp. (TSXV: ROS) (FSE: 2OJ) ("Roscan" or the "Company") is pleased to announce depth continuity in mineralization and positive diamond drill results (Figure 1) from an additional 4 holes totaling 771 metres (m) at its Mankouke South Target.

The drill program has extended the depth of the Southern Mankouke Target from 80m in February 2020 to 120m in mid-April 2020 and to 155m currently (Figure 2). Additionally, drillhole DDMan-20-31 depicts the depth potential to the North. The high grades (Figure 3) over large widths shown with these most recent drill holes have extended the depth of this target.

Highlights from Mankouke South Target:

• 4.84 gpt gold over 62.0m from drill hole DDMan-20-29 from 39.2m;
  • Including 12.7 gpt gold over 7.0m from 55.2m
  • Including 10.0 gpt gold over 13.0m from 73.2m

• 2.61 gpt gold over 31.0m from drill hole DDMan-20-29 from 110.2m;

• 4.76 gpt gold over 46.0m from drill hole DDMan-20-30 from 50.2m;
  • Including 18.6 gpt gold over 2.0m from 61.2m
  • Including 11.3 gpt gold over 10.0m from 85.2m

• 2.71gpt gold over 38.0m from drill hole DDMan-20-31 from 127.2m;
  • Including 9.81 gpt gold over 5.0m from 156.2m

• 2.18 gpt gold over 4.0m from drill hole DDMan-20-31 from 181.2m.

Notes: 1: True width yet to be determined, 2: Table 1 - Assay Highlights, 3: 0.5gpt used as cut-off with 4m internal dilution, and 4: No top-cut 5. Holes have a dip of -50° and azimuth of 270°

Nana Sangmuah, President and CEO, stated, "We are very pleased with these wide, high grade diamond drill holes results which represent the highest gram- meter intersections to date. These results support a mineralization to an approximate 155m depth which remains open. The geological understanding at our project is clearly improved with this round of drilling. Based on the current dataset it appears there is a northern plunge which is similar to other major deposits in the surrounding area. We continue to drill deeper and along strike to the North to ascertain the limits of the mineralization."

• Mankouke South remains open at depth and long strike to the North;
• Mankouke South Target drilling program continues to test strike, depth and plunge extensions of the mineralized system;
• Geological modelling exercises are currently in progress in order to understand and project this mineralized zone;
• Exploration has not been impacted to date by COVID-19 virus to date.

The gold mineralization at Mankouke South is associated with quartz veining (Figure 4) 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.). This mineralized system is structurally aligned with the Mankouke South mineralization that occurs in the structural corridor that also hosts the Siribaya deposits to the South (IAMGOLD Corp.), Roscan's Mankouke Central prospect along the 7km long Mankouke Corridor Target, and our neighbors to the North (Oklo Resources Ltd.).

Drilling Contract and Analytical Protocol

The drilling contract was awarded to Target Drilling SARL who employ KL900-1 multi-purpose (AC/RC/DD) rig at Mankouke South. The AC drilling contract was awarded to Geodrill and is currently drilling exploration targets.

All 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 10 gpt Au. Roscan applied industry-standard QA/QC procedures to the program. Certified reference materials, blanks and field duplicates are inserted at appropriate intervals.
