Roscan Gold Corp. Announces Drilling Results
Confirm the High Grade and Mineralization
Continuity at Mankouke South
Intersects 4.66 gpt gold over 41 meters and 3.18 gpt gold over
26 meters at MS1
Toronto, Ontario--(Newsfile Corp. - January 18, 2022) -
Roscan Gold Corporation (TSXV: ROS)
(FSE: 2OJ) (OTC Pink: RCGCF) ("Roscan" or the "Company")
is pleased to announce positive
results (Figure 1) from an additional 22 Reverse Circulation ("RC") and Diamond Drilling ("DD") holes
totaling 4,920 meters (m) at our Southern Mankouke Zone (MS1 targets). MS1 drilling has confirmed
additional mineralization outside currently defined areas and has confirmed MS1's excellent continuity
that will be included in the upcoming resource estimate.
The drilling at the MS1 Target in Mankouke South (the main resources target), demonstrates the
mineralization continuity at depth and dipping west, which remains open. The host rock is the clastic
sedimentary formations which extend from the surface. The mineralization then goes through the felsic
intrusive which crosscut the sedimentary layers. The ultra high-grade zone which lies close to surface has
also been reinforced by several holes such as RCDDMan21-136, which carried
4.66gpt over 41
meters
from 100m, hole RCDDNAB21-131 with
3.18gpt over 26m
from 32 meters and
3.67gpt over
21m
from 7m, and hole RCDDMan21-124 with
3.08gpt over 24 meters
from 19m.

Nana Sangmuah, President and CEO, stated,
"These additional results point to the excellent continuity
and high-grade potential at our flagship Mankouke South target, which is the core area for
establishing an economic stand-alone project at Kandiole.
The excellent high grade and near surface intersections should support a potential low strip high-
margin starter pit, which would further bolster project economics. We'd also like to highlight several
high-grade intercepts ending in fresh rock to be followed up with deeper drilling.
With approximately 16,000 metres of assay results pending from MS1, MS3, Kandiole, and other
regional targets, we expect continuous newsflow in the coming weeks."
Main Mankouke South Zone (MS1) - Recent Drilling Confirms Mineralization occurs in the
zones which received less density of drilling in the 2020 and 2021 previous drilling campaigns.
Additional results from the main Southern Mankouke Zone (MS1) show the occurrence of mineralization
where information was still pending in the geological model, confirming the continuity of the
mineralization.
Additionally, Holes RCDDMan21-124, 131, 136,138 and RCMan21-0067 continue to confirm the high-
grade nature of MS1, showing that mineralization is clearly defined with consistency over wide
intercepts. The MS1 target has been traced over a strike length of 550 meters and as wide as 150
meters in certain parts.
The felsic intrusive displays an important impact in the gold-bearing history, having a major role in the
alteration and mineralization event.

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
limestone. 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. In MS1 as well as MS3, the gold mineralization is often
associated at the felsic intrusion and located in the vicinity of the contact with the clastic meta-sediment
layers (greywacke-sandstone-breccia).
Drilling and Analytical Protocol
Roscan uses Reverse Circulation (RC) to drill until 120-150m and continue if it is necessary with a
Diamond (DDH) type of drilling to reach the target. For this campaign, Geodrill drilled mainly the RC
portion of the holes and Foraco the core to reach the target depth.
The samples are sent for preparation to the ALS Laboratories in Bamako, Mali and assayed at their
analytical facilities to Ouagadougou for 1 kg Bottle Roll with atomic absorption finish including tail
analysis for results more than 0.05ppm.
