Comprising of 42 claims on 2,444 hectares, the Frankfield East deposit currently contains approximately 348,000 ounces of gold in the Indicated category (1,621,000 tonnes at a grade of 6.68 g/t Au) and 838,900 ounces of gold in the inferred category (4,342,000 tonnes at a grade of 6.01 g/t Au). This deposit is open along strike and at depth.
The Frankfield East Deposit is located about 42 km north east of Timmins in the southwest part of Tully Township and is accessed by a 15 km all weather road leading east from highway 655.
Gold mineralization in the Frankfield Deposit occurs primarily within a fractured, sulphidized and brecciated hydrothermal alteration horizon at or near the contact with steeply north dipping (85 deg.) footwall ultramafic rocks to the south and hanging wall basaltic flow rocks to the north. This portion of the deposit is identified as the Main Zone. The mineralization is not confined to narrow vein-like structures (as can be seen in many other deposits in the area) but rather in a more massive/tabular structure than is consistently present throughout the mineralized horizon. This characteristic is shared by the major past gold producers in the Porcupine camp including Hollinger, McIntryre and present producer Goldcorp at their Dome and Hoyle Pond deposits.Pervasive silicification, minor ankerite veining, hematite staining along with the presence of tourmaline generate a recognizable mauve to pink hue for the mineralized zone. Total sulphide content of the mineralized horizon varies from 3-30% with occasional 2-5 cm wide bands of massive arsenopyrite and pyrite. The largest concentrations of sulphides correspond to the highest gold concentrations.
A second type of gold mineralization is hosted within the basalt flows. This mineralization forms multiple structures parallel to the strike and dip of the Main Zone and are referred to as Hanging Wall Zones as they are located immediately north of the Main Zone. They are seen as highly silicified zones accompanied by intense bleaching, brecciation and quartz flooding, tourmaline, 5-10% pyrite and arsenopyrite. A total of four such parallel structures have been identified in locations and are significant contributors to the total number of ounces of gold contained within the overall Frankfield Deposit and the density of gold ounces per vertical meter (thereby reducing development costs related to mining).
To date, the deposit has a drilled strike length of 800m and has been tested to a depth in excess of 900m. The width of the Main Zone varies from 2m to 22.0m. Widths of the Hanging Wall Zones typically vary from 2m to 4.0 meters.
