March 29, 2019, Vancouver, BC – Nicola Mining Inc. (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 ore 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.

The samples were run through a TOMRA COM Tertiary XRT sorter conveyor, which utilises an X-ray transmission (“XRT”) sensor. 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).

This study clearly indicates the ability to differentiate, and thus potentially upgrade, copper sulfide material encountered at Craigmont. 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-tonnes, surrounding the Craigmont Mine pit.
Additional studies are recommended to determine the ease of separation and performance testing in separating the differentiated ore from waste material and thus quantify these test results.

About Nicola Mining
Nicola Mining Inc. is a junior mining company listed on the TSX Venture Exchange and is in the process of recommencing mill feed processing operations at its 100% owned state-of-the-art mill and tailings facility, located near Merritt, British Columbia. It has already signed four mill profit share agreements with high grade gold producers. The fully-permitted mill can process both gold and silver mill feed via gravity and flotation processes. The Company also owns 100% of Treasure Mountain, a high-grade silver property, and an active gravel pit that is located adjacent to its milling operations.
About New Craigmont Property
In November of 2015, Nicola became the first group in decades to consolidate ownership of the New Craigmont Project (the “Property”) and has been actively conducting mineral exploration since. The Property is a wholly owned copper property with an active mine permit (M-68), located 33 km south of the world-class Highland Valley porphyry district. It lies at the southern contact between the Nicola Group rocks and Guichon Creek batholith, of which the latter is known to be a precursor to mineralization at Highland Valley. For further details on the Property, see the technical report entitled “Technical Report on the Thule Copper– Iron Property, Southern British Columbia, Canada”, filed on May 8, 2013 on Sedar at www.sedar.com.
