Callinex Mines Inc. announced results from a 10 line km deep penetrating surface pulse electromagnetic survey completed in January 2021 and the remaining drill results from the 2020 exploration campaign to expand the Rainbow Discovery at the 100% owned Pine Bay Project located in the Flin Flon Mining District of Manitoba (District Overview Map). The Rainbow Discovery has been made on the company's mineral lease, less than 250m from a high-voltage power-line and 550m from a historic shaft with direct road access to processing facilities in Flin Flon, MB. The company's technical team, working in conjunction with Koop Geotechnical Services Inc. ("Koop"), has identified four highly conductive anomalies located near-surface and along strike to the south of the Orange and Yellow zones of the Rainbow Discovery. The Survey was completed based on the success to date of the Rainbow Discovery and the area to the south had not previously been covered by any deep penetrating electromagnetic system. The identified anomalies expand the strike extent of the Rainbow over 1 km to the south. The three major base metal mines discovered in the Flin Flon/Snow Lake Greenstone Belt with tonnages ranging between 25 – 70 million tonnes (Flin Flon/777, Trout Lake, Chisel/Lalor) have a strike length over 1 km. Based on the recent survey, the Rainbow Discovery has a strike length of at least a kilometre with potential to grow further along strike to the south (See Rainbow Discovery SPEM Survey Plan View). Drill Hole PBM-113-W2 intersected the Rainbow Horizon 225 metres vertically above the PBM-111 discovery hole which demonstrates that mineralization will continue to be defined closer to the surface. Correlation between its parent hole PBM-113 which is 100 metres vertically below PBM-113-W2 is supported by the intersection of the Orange Zone which returned 5.7m of 4.72% copper equivalent (CuEq) comprising of 3.57% copper, 0.54 g/t gold, 21.41 g/t silver and 1.56% zinc. PBM-114 tested the Rainbow Horizon 150 metres below hole PBM-112 in an effort to better define the southern edges (plunge) of the Yellow and Orange zones. Narrow widths associated with the Yellow and Orange zones in PBM-114 suggests future drilling needs to trace northerly from this location. PBM-115 was designed to test the northern strike extent of the Orange and Yellow zones and represents a 75 metre step out from PBM-113-W1. PBM-115 intersected the Yellow Zone 783 metres down hole and intersected 3.13m of 1.95% CuEq consisting of 1.45% copper, 0.20 g/t gold, 6.76 g/t silver and 0.82% zinc.
