Sparton Resources Inc. announced the findings of an Induced Polarization (IP) survey conducted recently over the central portion of the Oakes Gold Project Property near Matachewan, Ontario.

The Company owns 41 claims and three leases in the area, all of which are connected to the larger property that houses Alamos Gold Inc.’s Young Davidson Gold Mine (annual gold production of approximately 200,000 ounces). Road and bush trails provide easy access to the Oakes Property.
Canadian Exploration Services (CXS) of Larder Lake, Ontario, completed the IP survey. A 3-D Distributed Induced Polarization system was used, along with multiple layer data presentation and wireless data acquisition.
This system has a lower environmental impact because it decreases the amount of line cutting required, and it was also helpful in obtaining data from beneath the lake, which cuts the survey area in half. At 50 m vertical intervals, data is presented as both resistivity and chargeability information, beginning at the surface and widening to various depths below the surface.
This information can be used to create a 3-dimensional representation of the bodies that are causing the anomalies. Higher chargeability zones are generally associated with metallic minerals in the host rocks, while higher resistivity zones are often linked with gold mineralization.
Survey Results
The findings reveal five (5) areas that are significantly abnormal. One of these anomalies (Anomaly “D”) is directly linked to a mineralized area near Hawley Lake adjacent to the old “Oakes” shaft, where Sparton drilled several holes in late 2020.
All of the holes had pyrite, magnetite and hematite mineralization, as well as quartz veins and intense silicification. These drill holes produced anomalous copper, silver and gold values. Mineralization happens in syenite porphyry and brecciated sediments. At the Alamos Young Davidson Mine, syenite porphyry is one of the key host rocks for gold mineralization.
Other IP chargeability anomalies had not been tested with trenching or drilling and were unidentified until the survey results. At least two of them (anomalies “C” and “E”) seem to be linked to syenite porphyry rocks on Hawley Lake’s west side. The 2020 drill program only assessed a small portion of Anomaly “D” near the old shaft.
Ongoing Program
Sparton intends to conduct a trenching program based on these findings to uncover the sources of the new IP chargeability anomalies. After the Ontario Government approves amendments to the existing work permit, the work is expected to commence later this summer. Following up on the positive trenching results, a new drilling program will be implemented.
The Company is extremely pleased with these results. We are quite optimistic that the trenching work will provide positive information to justify a new drill program later this field season. Some of the anomalies appear to extend on to Alamos Gold’s claim holdings and may be of interest to them.
