The 43-101 did not address strip ratios. The ore is flat lying, which implies a low ratio under certain circumstances.

In 2007 six more samples were submitted to Hazen Research for additional gold characterization studies. These samples represented both high and low grade mineralization from oxidized, partially oxidized and unoxidized material. The study is ongoing, however, preliminary cyanidization results have been received. These show that the cyanide extraction is very high on the oxide samples and partially oxidized samples (Table 3) and somewhat less in the sulphide material. Two of the sulphide samples (Table 3, samples 3 and 1A) were from the albitic alteration style and they each returned 60% cyanide recovery. The 3rd sulphide sample (Table 3, sample 5) came from the sericite alteration style and has only a 42% recovery.

A very important result of this work to date is the fact that, in all the samples tested in 2007, the bulk of the gold recovered by cyanide extraction comes out in the first 6 hours. This implies that the gold is readily available to the cyanide solution. The second part of this study will address the cyanide extraction on coarser material as well studying the actual mineralogical association of the gold
