Drilling at Mont Agoma Prospect (cont.) 9 Significant tin, copper & zinc mineralization defined over 300m of strike at Mont Agoma • Assay results received for first 4 drill holes - intersected near surface extensions of tin zones, results include: 4.4m at 1.03% Sn from 36m & 1m at 1.3% Sn from 46m (MADD002) 11.25m at 0.51% Sn incl 2.25m at 1.06% Sn from 5.75m (MADD004) ⚫ Subsequent drilling targeted deeper mineralization - intersected significant (5-30m) zones enriched in tin (visible cassiterite) & strong visible copper Indications are tin mineralization increasing in grade & width at depth similar to Mpama South & San Rafael (Peru) Program confirms presence of significant tin & copper mineralization at Mont Agoma - next phase of drilling to test strike & depth extensions Southwest (A) Significant Sn Intercepts Significant Zn Intercepts Mineralisation RL 800m Sn Sn/Cu/Zn Zn Zone 66m at 2.31 %Zn RL 700m • Assays pending - results expected in August 100 2m at 0.13 %Sn MADD002 MADD007 200 MADDOOS 4.4m at 1.03 %Sn Sn Zone 1m at 1.30 %Sn 0.5m at 0.13 %Sn 90m at 4.01 %Zn 1.5m at 0.19 %Sn 0.65m at 0.14 % Sn 0.40m at 0.14 %Sn 100 1.00m at 0.13 %Sn Zn & Anomolous Sn Zone (Open Down-dip) Sn/Cu/Zn Zone (Open Down-dip) 200 300 MADD010A 300 Northeast (B) Zn Zone Meters 50 100 MADD015A
