Dec 07, 2005 (A Wilson) - Isolated fragments of iron formation have been mapped within mafic metavolcanics on the east side of the Firesand River Fault. The north end of the Firesand River Fault terminates in the area of a short cross-fault that joins the strike-slip Wawa - Hawk Lake fault. It terminates to the south in the vicinity of the SE extension of the Parkhill Fault. The juchtio of the Wawa-Hawk Lake faults and the transverse Firesand River Fault may have been the controlling structural influence for the emplacement of the Firesand River Carbonatite.

Dec 07, 2005 (A Wilson) - The occurrence consists of several bands of sulphide-facies iron formation. The NE or footwall side of the iron formation consists mainly of pyrite and interbedded fine-grained sugary quartz. It is overlain to the south by magnetite-chert iron formation. Massive to pillowe mafic metavolcanics overlie the iron formation. All units have been intruded by granodiorite and quartz-feldspar porphyry which is presumably related to the adjacent Hawk Lake Batholith. Talc-actinolite schists have been mapped to the south-east of the occurrence and have been interpreted to be ultramafic flows. These may be related to the ultramafic rocks mapped to the north of the Wawa-Hawk Lake Fault in Esquega township.

Dec 07, 2005 (A Wilson) - Gold values have been reported to range from 0.06 to 0.33 oz/ t from grab samples taken within the iron formation in the 1930's. Grab samples taken since then have been unable to replicate these high values but anomalous gold values have been returned from all rock types in the vicinity of the old trenches and pits.
