(TSXV: NIM) (the \"Company\") is pleased to announce positive results from Outotec's Initial Inspection Study, in which select material from the terraces and highly mineralized zones at the wholly-owned New Craigmont Copper Project (\"Craigmont Project\") was evaluated. The test work was conducted at Tomra Sorting's Test Center in Hamburg, Germany. This study successfully demonstrated that the COM Tertiary XRT Sorter can clearly distinguish ore1 from waste material. The material used in the Initial Inspection was comprised of 29 representative samples of waste, low-grade ore (\"LG ore\"), ore, and high-grade ore (\"HG ore\") (Figure 1). These samples were collected from the terraces and targeted zones that represent ore material at the Craigmont Project.Figure 1: Samples of material tested for copper separation.

Succinctly, this XRT sensor x-rays the rocks, which are processed to identify differences in atomic density between copper-containing mineralized material (high atomic density, blue areas in Figure 2) from waste material (low atomic density, red areas in Figure 2).Figure 2: Examples of samples tested with the X-ray transmission (\"XRT\") sensor.

The conveyor system has a throughput capacity of up to 400 tonnes per hour and can be set up in parallel lines. The Company believes that the ability to distinguish and separate copper sulfides from waste rock is of great significance for monetizing copper contained within the historical mine terraces, which equate to approximately 80-90 million-tonnes2, surrounding the Craigmont Mine pit.Additional s...
