Dec 07, 2005 (K R Kettles) - The Golden Chance Partnership KRL 11052A occurrence is in an area underlain by chert-magnetite iron formation and mafic and felsic volcanic rocks. A trench in the iron formation contains pyrite, sphalerite and gold. This occurrence may have similarities with the Biron Bay Main Zone.

| Mafic lava flow-unsubdivided | 2 | Near | ||
| Felsic lava flow-unsubdivided | 3 | Near |
Jul 31, 2020 (Therese Pettigrew) - Geology consists of interlayered folded iron formation, foliated mafic rocks and both fine-grained and quartz crystal-bearing felsic rocks. Stratigraphy generally trends east-southeast with northerly dips of 60 to 70 degrees (Assessment report 52M01SE2034).

Dec 07, 2005 (K R Kettles) - A trench in the iron formation contains pyrite, sphalerite and gold. A grab sample collected in 1969 contained 0.12 opt Au, and 0.19% Cu.
Jul 31, 2020 (Therese Pettigrew) - A grab sample from the 700 Zone taken in 2003 returned 4.57 g/t Au from a 5-15 cm quartz vein with 2-5% pyrite and <1% chalcopyrite. Channel samples were taken across the iron formation and across irregular smoky quartz veins within a 1 to 4 metre wide felsic unit from which the original anomalous grab sample was taken. Sulphide mineralization at this showing is confined to the originally sampled vein which assayed 4.57 g/t gold (Assessment report 52M01SE2034).
