Roscan Gold Discovers New High-Grade Zone at Mankouke West Intersects 3.44 gpt over 31m, including 9.23 gpt over 3m

Toronto, September 11, 2023 - RosCan Gold Corp. (TSXV: ROS) (FSE: 2OJ) (OTCQB: RCGCF) ("Roscan" or the "Company") is pleased to announce that it has identified a new high-grade zone of gold mineralization at Mankouke West (Figures 3, 4 and 5) as a result of its systematic regional exploration activities. Discovery holes include RCMAW23-0009 with 3.44 gpt over 31m, including 9.23 gpt over 3m, 8.46 gpt over 3m, 3.75 gpt over 7m, RCMAW23-0001 with 1.72 gpt over 28m, including 5.28 gpt over 6m and RCMAW23-0017 with 1.14 gpt over 50m including 4.08 gpt over 2m (Table 1).

The new discovery is located 2km NW from Mankouke South, close to the area which holds over two thirds of Roscan's maiden resource. This new zone has been traced so far over an area with a strike length of 450m, 50m wide, and 125m vertical depth, and it is open toward NE and SW and at depth. This gold occurrence lies in a large footprint of about 2km long and 500m wide outlined by saprolite geochemistry with arsenic and antimony pathfinders providing expectation for substantial extensions (Figure 6).

This discovery demonstrates the additional gold potential along the Siribaya-Mankouke-Kabaya-Seko regional structural corridor, which stretches over 20Km through Roscan's land package. Further drill holes are planned to develop this new gold target, with extensive RC holes, followed by deeper Diamond drill holes.

Nana Sangmuah, President and CEO, stated, "This high-grade discovery remains open on strike for about 2km and at depth and highlights the excellent prospectivity of our tenement package. This points to further resource growth potential outside the limits of known resources. The proximity of this new zone to the main Mankouke South resource area could enhance ore feed to a potential central processing facility. Since December 2022 we have completed about 10,000m RC and 5,600 meters of auger drilling to expand the footprint of current resources and results should be available in the coming weeks".

Exploration

The new Mankouke West mineralization is located along an NNE-SSW portion (Figure 2) of the NE-SW regional structural corridor as shown in Roscan Airborne Geophysics survey. This corridor extends from Siribaya (IAMGOLD/MANAGEM) to Seko (B2GOLD) passing through Roscan's land package (Mankouke South, Kandiole, Kabaya and Moussala targets) (Figure 1).

This discovery follows a saprolite geochemistry that initially provided low gold results but strong arsenic and antimony signatures, defining an anomaly over 2km long and 500m wide tested by several scissor Air Core fence lines (80m holes length), which returned a significant 2.12g/t over 12m intercept. The RC holes reported in this press release confirmed the gold occurrence and allowed us to interpret its geometry.

The mineralization occurs mainly in the saprolite horizon. The host rock is clastic sediments rich in quartz veins fragments and iron oxide from sulfides.

The gold mineralization at both Mankouke South and Mankouke West is located on the edge or in the vicinity of an intrusive pluton which is probably cutting the main mineralized body (MS1) with its NW extension contouring it (MS3) as shown in the Electromagnetic Airborne geophysics interpretation (Figure 2). This acid intrusive likely played a role in the hydrothermal activities, carrying gold in the more porous or brittle host rock.

Drilling and Analytical Protocol

Roscan uses Geodrill Reverse Circulation (RC) to drill until maximum 170m to reach the target. In 2021, (Air Core holes ACMAW22-1158-1162), the samples were sent for preparation to Bureau Veritas' Bamako laboratory and 1 kg Bottle Roll with atomic absorption finish analysed in BV lab, Abidjan. Since January 2022, the samples are sent to the ALS Laboratories in Bamako, Mali and assayed at their analytical facilities in Ouagadougou for 2 kg Bottle Roll with atomic absorption finish including tail analysis by fire assays for results more than 0.05ppm. Roscan applied industry-standard QA/QC procedures to the program using reference materials, blanks, standards, and duplicates.
