Toronto, Ontario--(Newsfile Corp. - March 23, 2022) -
Roscan Gold Corporation ("Roscan" or the
"Company") (TSXV: ROS) (FSE: 2OJ) (OTCQB: RCGCF)
is pleased to announce positive Reverse
Circulation ("RC") drilling results at Kabaya (Figure 1) from an additional 53 holes totaling 5,969 meters
(m) at Kabaya.
In order to both discover new gold zones outside our existing resource area and to expand the potential
gold resources in our existing resource at Kabaya, Roscan designed an aggressive RC drilling
program.
This drilling was comprised of 60% step-out holes to test for
new
gold zones along the North South strike
from KB1 to cover the underexplored zone between KB1 and KB3. The remaining 40% of the RC drill
holes were focused on an infill drilling program in KB1 and KB2. The excellent gold recovery of 95.65%
in saprolite from the metallurgical test work (News release of October 25, 2021) with near surface
mineralization points to the economic potential of these targets.
The current drilling results at KB3 outlines
an estimated strike length of 200m, a width of 80m and a
100m vertical depth. This zone is open at depth and laterally. There is an 850m gap between KB3 and
KB1-2, the main gold mineralization that is yet to be fully tested.
The infill holes at KB1 and KB2 enlarge the different grade envelopes and has infilled some areas to
expand the continuity of the gold mineralization. KB1 and KB2 have a combined strike length of 985m, a
horizontal width of 180m wide and still open to 225m vertical depth at KB1.

Nana Sangmuah, President and CEO, stated
, "
Drilling at Kabaya
continues to expand the footprint
of the gold mineralization which bodes well for the pending maiden resource in Q2. We are excited by
the fresh rock intercepts at KB3 that points to a larger mineralized system within the 850-meter gap
zone between KB1-2 and KB3, which is yet to be fully tested.
We are currently drilling additional RC and Diamond holes at our Mankouke, Disse and Kandiole
targets and look forward to reporting additional assay results as they become available."

The gold mineralization at Kabaya (Figure 2-3) is disseminated and associated with a strong
kaolinization after the saprolite process going deep between the fresh foot and hanging walls. From the
few fresh rock observations, this powdery zone corresponds with the albite-dolomite-pyrite-arsenopyrite
alteration in a volcano-sedimentary sequence. The gold host rock is an alternate between tuffaceous and
greywacke facies. As in the Mankouke gold deposit, the carbonaceous bedded mudstone constitutes
the folded footwall. The gold zone is also limited by an NNE-SSW weakness, fractured, and sheared
zones in hanging and foot walls contacts.

The Kabaya Deposit is part of a prolific regional Siribaya-Mankouke-Seko structural corridor (Figure 4).
The Kabaya gold orebody is likely on an NNE-SSW splay structure contouring the Disse quartz diorite
intrusion from the VTEM
(Versatile Time Domain Electromagnetic) airborne survey interpretation. The
Roscan large land package covers well this major auriferous structure over 25km, including the splays
around Disse intrusive, occurring new gold discoveries.

Drilling and Analytical Protocol
Roscan uses Geodrill Reverse Circulation (RC) to drill until maximum 170m to reach the target. In 2021,
(holes RCDBS21-026 to RCDBS21-048), the samples have sent for preparation and 50g fire assays to
Bureau Veritas Bamako laboratory and since January 2022, the samples are sent to the ALS
Laboratories in Bamako, Mali and assayed at their analytical facilities to Ouagadougou for 2 kg Bottle
Roll with atomic absorption finish including tail analysis for results more than 0.05ppm. Roscan applied
industry-standard QA/QC procedures to the program using reference materials, blanks, standards, and
duplicates.
