Anniv Deposits
The Anniv Central and Anniv East deposits are part of a continuous zone of mineralization that is defined by 183 drill holes over more than 9 kilometres, including the extension to the northwest that is referred to as Anniv West. Each of Anniv Central and Anniv East deposits contain significant tonnages of near surface mineralization amenable to open pit mining as demonstrated in the 2006 NI 43-101 mineral resource estimate:

Similar to the deposits in Don Valley, deep drilling beneath the Anniv Central deposit has defined higher grade mineralization drill hole ANC-153 intersected 8.70 metres grading 6.97% zinc and 3.57% lead that includes a 1.67metre interval of 16.37% zinc and 13.07 % lead. Drill hole ANE-136 intersected 9.16 metres grading 8.35% zinc and 3.45% lead at depth in the Anniv East deposit.
The extent and distribution of the higher grade mineralization is an important focus for future drilling programs. Importantly the deep mineralization at Anniv Central deposit is located at the approximate same elevation as Don Valley and is therefore readily accessible by horizontal adit and therefore is attractive for early mine development.
