Price assumptions used are based on market consensus forecasts with adjustments to account for reasonable prospects for eventual economic extraction (RPEEE), as guided by JORC reporting guidelines. Gold equivalent (AuEq) and copper equivalent (CuEq) conversion factors are used within the presentation and are calculated by multiplying the grades for each contributing metal by their respective metal price and recovery and dividing by the multiplication of the primary metal’s price and recovery (gold or copper for AuEq and CuEq respectively). Metallurgical recoveries are based on historical production (2010-2016) as well as recent metallurgical test work and are applied to the Resource and Reserve calculated grades for each commodity. The Company is of the opinion that all the elements included in the metal equivalent calculations have a demonstrated potential to be recovered and sold. Mineral Hill has a fully approved mine and processing plant, capable of producing metal concentrates and dorѐ (from the flotation and CIL circuits). The Company is targeting a recommencement of mining and processing to produce copper, lead and zinc concentrates as well as precious metal dorѐ.
