In 2020, Goldseek Resources acquired the Southern Arm Property on the Detour Gold Trend. The detour belt has hosted some world-class mines and deposits which include:
1. Fenelon (Wallbridge Mining Company Limited): 2018 – 2019 bulk sampling provided 33,233 tonnes at 18.49g/t Au. 100 – 120,000 meters of expansion drilling planned for 2020. (Source Wallbridge Website)
2. Martiniere & Bug Lake Gold Zones (Balmoral Resources): “In March of 2018 Balmoral published an initial resource estimate for the Martiniere Gold System on the property which outlined 591,000 ounces in the indicated resource category and an additional 54,000 ounces in the inferred Category.

3. Detour Lake Mine (Kirkland Lake Gold): The Detour Lake mine hosts gold reserves of 15.61 million ounces of gold.
Historical Work on the Property
Numerous EM anomalies have been reported over the Bapst Fault(17). Public reporting indicates that conductor anomalies are located on the property(16), such as VTEM targets(6). The major anomalous zones are oriented NW-SE and have associations with the magnetic anomalies. According to the detailed resistivity depth imaging, the top of the EM response sources varies in depth from about 50m-500m deep.
Eleven holes were drilled on the property from 1993 to 1995, mainly to test magnetic anomalies. Most of them intersected disseminated Au-Cu-Zn sulfides (pyrrhotite, chalcopyrite, pyrite)(9-13) but returned low values of these metals. Mineralization appears to be located in an exhalite horizon or dacitic/basaltic rocks.
A full review of the historical work conducted on the Property will be done, including the review of historical results from drill holes and statistical treatment of the available geochemical data.
The targets are all spatially related to the Bapst fault, of which the Company has 7.3 kilometers of strike length. The Bapst fault hosts multiple mineralizations along its strike in the area, outside of the Property: the SG3-1 silver showing grade 5.6 g/t over 1.4 meters; the 93-BA-A-07 showing contain 1.9g/t Au over 2.5m, including 4.1 g/t Au over 0.9m.
The main target is named Target 1, which has never been drilled. It contains multiple interesting features that indicate the potential for gold mineralization:
- A break in a conductive anomaly is located along the Bapst fault 2.4km from Target 1. This indicates a change in the mineralogy of the host rock.
- At the target’s NW edge, a break in the magnetic signal is also visible. A shift of the magnetic unit toward NE is present and indicates a potential NE-SW fault that cross-cuts the magnetic signal. This fault may well be related to multiple gold showings located SW of the Property (H-1432-068; Ruisseau Twinning; Lac Sicotte-NE and Lac Sicotte).
- Prior drilling indicates that the conductors on the Bapst fault, along the magnetic anomaly, are formational conductors and mostly generated by graphite mineralization associated with sulphide. A local conductive anomaly is located at Target 1. This indicates to the Company that the conductor is not formational in nature and could better be related to sulphide mineralization rather than graphite.
- Multiple high gold anomalies in till are found directly down-ice from the Property, and their source is most likely on the Property. Previous RC drilling with till sampling purpose showed anomalies of 4,790; 4,690 and 7,110 ppb Au in three different holes located respectively 250m; 2 km and 4.7 km away from the Property limit, located up-ice from the anomalies.
The Company also identified Targets 2 and 3, which are related to conductive anomalies located along the Bapst fault. Previous drilling was performed on these targets, and the Company will review historical drill logs to find out a new way to investigate them, including a till sampling strategy. The conductive anomalies are explained by exhalite horizon that contain sulphide and graphite mineralization. Those horizons are responsible for the SG3-1 showing previously mentioned. Both targets could also be a source of the till anomalies discussed above. Figure 1 shows the targets on the Property.
