The area of the Lisa 11 showing is underlain by marine sedimentary and volcanic rock of the Devonian to Permian Stikine Assemblage. The stratigraphy is intruded to the north by the Late Triassic Seraphim Mountain pluton consisting of quartz monzonitic rock and to the south by Eocene intrusions of the Coast Plutonic Complex.

Corona reports a vuggy quartz vein on the Lisa 11 claim with galena and sphalerite.

In 1989, Corona Corporation prospected the LISA 8, 9, 10, 11 and 12.claims (of the Inhini property) and collected 14 heavy mineral, 17 silt and 16 rock samples (Assessment Reports 19970). Corona reports that where mineralization occurs, silver (plus/minus) is the predominant precious metal on the property. Generally, gold values are low. All quartz veins located on the property are too short, narrow and low-grade to be of any economic value.

In 1990, Link Resources Inc carried out a 700-kilometre airborne Mag and EM survey over the entire Inhini Property (Assessment Report 20972).
