Here's one geologist that thinks there is something big here:

In June 2010, Paul D. Gray Geological Consultants (“PDGGC”) were commissioned to author a

technical compilation, review and update report (“the Report”) on the Tesoro Property. On June

6 – 8, 2010, Paul D. Gray, P.Geo. conducted a site visit and Property inspection of the Tesoro

Property (verification assays returned grades up to 231.12 g/t AU)

I'm not sure if he is invested in SLI, but he is now a director for IGD.
