This copper zone is hosted in a grey sandstone at the base of the Namurian aged Shepody Formation. The copper was a discovery of malachite staining in sandstone of the Shepody Formation near the contact with the underlying Maringouin Formation (yellow line Map 1). This horizon is commonly mineralized and typically associated with plant debris within the grey sandstone sequences. Controls on mineralization at Midway are not known to be fault related, unlike part of the Upper New Horton Deposit. Historical work in this area was mainly limited to the upper northeastern 800 m section of the contact with some trenching and four drill holes; however, no modern exploration or geophysics (Marex Ltd (NB Mineral Report of Work 470535) in 1965, Keith Hope (NB Mineral Report of Work 470534) in 1967, and Garnet Flaherty (NB Mineral Report of Work 470533) in 1964) has been carried out. The mineralization is primarily chalcocite coated with malachite, which is replacing carbonized plant remains similar to mineralization at the Dorchester Copper Deposit. A small soil survey over the contact identified copper anomalies (green lines Map 2) There are also trace amounts of gold, with one sample collected by DNR staff (D. Rose) from pit #6 that assayed 0.02 oz/ton Au over 2 ft (0.6 m). The best historical copper value is 4.52% Cu.

Given the historical work outlined above, more than 3 km of anomalous copper in soils along the contact, with some of the best soils and outcrop not being investigated by either trenching or drilling (Map 3), Geosearcher Inc. staked this ground in April of 2021 realizing the potential and extent of this overlooked area. The overlooked zone of mineralization stretches for an additional 2.5 km beyond the above mentioned 800 m zone, with 1.8% Cu discovered in a small pit at the furthest extent of the know mineralization. On a second trip to the area, an exciting new copper outcrop was discovered along the contact between the two historical discoveries within the southern tip of the anomalous copper in soils area, indicating the potential for additional copper mineralization along the contact in both directions.

2021 Updated Results
The 2021 assay results were very encouraging.  They confirmed historical grades with highly anomalous copper and silver. The highest value being 4.3% Cu and 60 ppm Ag from a previous trench site that had not been historically tested. These two new discoveries (See Map 4) have significantly extended the historically recognized mineralized zone further to the southwest, indicating the potential that ore-grade copper could extend the entire 3 km stretch. The historical review highlighted and advanced the understanding of the initial 800 m zone of mineralization with copper grades far exceeding the originally reported 4.52% Cu (Map 4 – Drill Hole 3 with 22% Cu, dump next to shaft 7.8% Cu). Further investigation is warranted. The focus of the 2022 season will be to further identify mineralized outcrop along this 3 km length of copper mineralized contact.
