Geology
Skarn Gold Deposits
The highest grade (5-15 g/t Au) gold skarn deposits are relatively reduced, are mined solely for their gold content, lack economic concentrations of other metals, and have a distinctive Au-Bi-Te-As geochemical association. Most high-grade gold skarns are associated with reduced (ilmenite-bearing, Fe2O3/( Fe2O3+FeO) << 0.75) diorite-granodiorite plutons and dike/sill complexes. They typically occur in clastic-rich protoliths rather than pure limestone and skarn alteration of dikes, sills, and volcaniclastic units is common.
Porphyry gold
Porphyry copper deposits are among the largest reservoirs of gold in the upper crust and are important potential sources for gold in lower temperature epithermal deposits. Whether gold remains in porphyry copper deposits is important both to their economic attractiveness and to the distribution of gold in the upper crust.
Gold is found in porphyry copper deposits in solid solution in Cu–Fe and Cu sulfides and as small grains of native gold, usually along boundaries of bornite.

History
Barker Minerals has completed Core drilling and surface sampling of Laurion and surrounding area as detailed in their technical report 29740.
DDH K07-5 This was in the area of an As and Au soil anomaly from a reconnaissance soil line done in 2005. The highest Au (5,220 ppb) in soil was on the adjacent line west though without an associated geophysical anomaly
Barker Minerals also completed an airborne survey of Laurion claim and surrounding area. Pertinent results are included with this report. The following highlights findings that are shallow depth (less than 200meters) and hold placer potential. Pyrrhotite is responsible for the magnetic quality of rocks commonly observed in core and outcrop. Magnetite was rarely identified.
The most significant portion of T1c is on line KL-6 at station 1750N. Significant depth extent, strong IP (>40 milliradians) and coincident MT resistivity low (<500 ohm-meters) is observed, suggesting massive mineralization at depth.
The massive mineralization at 1750N has not been sampled or drilled. The potential for disseminated mineralization trending west north/west from 1750N has not been sampled or drilled. It must also be noted that KL-6 1750N appears to be defining only the western edge of this massive mineralization. It is reasonable to suspect that the mineralization continues east of 1750N including a zone of disseminate mineralization trending into Kangaroo Gulch. Due East of Station 1750N on KL-6 is Kangaroo Gulch (1.8km). and the location of Aaron Doyle Technical Report 34603 describing rich placer assays. Our drilling program follows the North/South access road that crosses what is a suspected to be an unexplored at depth East/West placer channel.
