Is a mineral that can be associated with - more economics?
Jacques Vaillancourt, Chairman of Mineral and Financial, stated that -�These results from TH Crestgate
were better than we had expected. Metallurgy is an important determinant of the economics of the Iberian
Pyrite Belt ore bodies. The good liberation of the sphalerite and galena appears to match, and we believe
it could perhaps exceed that of neighbouring major operating mines. Secondly, the major contaminant
appears to be arsenopyrite, which can be preferentially excluded from the final concentrates. Thirdly, the
ore from the Central Sector is very clean and could easily be blended into the LS-1 concentrate, which
would serve to reduce any overall penalties from the smelters. Lastly, the big surprise was the presence of
high-grade (2.25% Sn) tin in the Gossan. TH Crestgate had not initially asked ALS to assay for tin when
testing the core from the 2017 drilling campaign. On the back of this result, a sample from LS-MS-01 has
been resent to ALS for a secondary assay to confirm the presence of tin in the sample. �
