Highlights

• 5-year, renewable mining lease agreement signed between Polymet and Minera KMT SpA
• Minimum monthly production of 2,500 tonnes to be maintained after a 7-month development period
• 2015 - 2017 mining produced 12,905 tonnes of ore containing 528,168 lbs of copper, 2,829 Oz silver, 95 Oz of gold
• KMT to begin mining in historic workings at Level 7 within known high-grade copper-bearing mineralization
• Polymet will receive a monthly revenue stream equal to 10% (minus 1.5% existing royalty) on all Cu, Ag, Au ore sales, and 15% (minus 1.5% existing royalty) for cobalt-bearing ores

Mining Operations

Historic mining activities contracted by Polymet at the Carrizal Property between 2015 and 2017 resulted in a total of 12,905 tonnes of sulphide ore transported to the ENAMI processing facility. This ore material was found to contain a total of 528,168 lbs of copper, 2,829 Oz of silver, and 95 Oz of gold, translating to overall grades of 1.86% copper, 7.8 g/t silver, and 0.23 g/t gold. Oxide ore in the upper levels totaled 1,814 tonnes grading 1.56% Cu (see Figures 1 & 2 below).

The lease agreement outlines that KMT will extract a minimum of 2,500 tonnes of ore after a seven-month development period to keep the contract in good standing, thereby providing a consistent revenue stream for Mineral Polymet SpA and Red Metal's Chilean operations. KMT is also responsible for annual taxes on the Farellon 1/8 mineral concession throughout the term of the contract. The term of the mining contract is five years and can be renewed.

KMT will commence operations on the Farellon 1/8 mineral concession, a 66 hectare concession within the larger 3,278 hectare Carrizal Property. KMT plans to rehabilitate the historic workings and begin mining on Level 7 from which a total of 5,080 tonnes of ore were extracted between 2016 and 2017, grading 1.97% copper, 9.62 g/t Ag, and 0.14 g/t Au. Copper and gold grades within the sulphide mineralogy have been shown to increase and become more consistent with depth in the historic workings (see Figure 2).
