News in a flash: New magnetic targets similar to the high-grade gold Minto pipe were identified. Ground follow-up and sampling we have confirmed the presence of coincident gold and arsenic anomalies in bedrock similar to the environment around the high-grade Minto pipe. A total of eleven anomalies including the response on the Minto pipe have been labelled as significant targets. All ten new anomalies need to be surveyed by induced polarization (IP) geophysics and a significant IP response on any of the targets will upgrade the anomalies to high priority drill targets. This would be a significant development for the Knight Project.

Toronto, Ontario – November 1, 2019 – Orefinders Resources Inc. (“Orefinders” or the “Company”) (TSX.V: ORX) is pleased to announce that it has completed its exploration program on the Knight Project in Shining Tree and all analytical results have been received from the laboratory. The data confirms the presence of gold and arsenic in bedrock anomalies coincident with Minto-type magnetic features and a total of ten (10) new targets have been outlined between the Minto breccia and the western shore of Porphyry Lake over a strike length of approximately 2.3 km.
“We were encouraged with the recent geophysical data processing from our Knight project which identified additional magnetic features like that of the Minto. We were further encouraged when our on-site program discovered coincidental outcropping near these anomalies, which we’ve since sampled and returned geochemical gold-arsenic anomalies that are consistent with wallrocks surrounding Minto. The idea is that if we can discover one or more of these very high-grade breccia pipes, it would transform the dynamics of our Knight project,” said Stephen Stewart, Orefinders’ CEO.
Results of the Exploration Program
Breccia pipes like the Minto are created in response to regional structural/hydrothermal events and as such tend to cluster in districts. However, no other such breccia pipe has been found in the Shining Tree area. Breccia pipes such as the Minto are associated with intense alteration and low to moderate levels of gold and arsenic in surrounding rocks that may show a geophysical signature. As described in its September 3, 2019 news release, Orefinders reprocessed a high resolution heliborne magnetic-radiometric survey over the project area and demonstrated that the Minto breccia is indeed visible on certain gridded magnetic maps including the Tilt-dv product. The rocks surrounding the Minto breccia are also characterized by a strong arsenic in rock anomaly that correlates with anomalous gold values. Moreover, historical work on the Minto breccia pipe also showed it responds well to induced polarization geophysics but that the small size of the target requires very tight line spacing that would be prohibitively expensive to undertake at the property scale. However it would be very cost-effective to survey specific targets suspected of being a pipe and prioritize any anomalous response for drill testing.
A total of 44 magnetic anomalies similar to the signature found at Minto were identified and visited in the field. Each anomaly was visited and then circled up to a radius of 75 metres in order to explain the anomaly, in case it outcropped, or at least locate nearby outcrop and collect bedrock samples for multi-element analyses.
Two datasets were used to interpret the anomalies; Orefinders’ own sampling (37 bedrock samples) was complemented by a previous rock geochemistry survey done by Jamie Walker, the previous owner of the claims, who collected 155 rock samples within or near the Breeze Lake volcanics, of which a total of 74 samples were collected within a radius of 100m from Minto-type magnetic anomalies. Table 1 summarizes the anomalous results. A total of 11 coincident magnetic and bedrock arsenic-gold anomalies were outlined in this survey including the Minto breccia itself (Figure 1) and all the targets are located between the Minto breccia itself and Porphyry Lake over a strike length of approximately 2.3 km.

Future Work at Knight
Follow up exploration on the Minto-type anomalies will comprise additional prospecting on the 10 targets as well as line cutting and induced polarization geophysical surveying over the best targets represented by the combined magnetic and geochemical responses. Any anomalous IP response on any of these anomalies will be considered a high-quality drill target.
