Notes to accompany Mineral Resource estimate, and parameters used by P&L Mining Consultants Inc. for the 2018 J&L resource estimate: 1) Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues. 2) The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration. 3) The Mineral Resources in this estimate were calculated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council. 4) The following parameters were used to derive the NSR block model cut-off values used to define the Mineral Resource: Dec 31, 2017 US$ two year trailing avg. metal prices: Pb $0.95/lb, Zn $1.13/lb, Au $1,253/oz, Ag $17.08/oz; Exchange rate of US$0.76 = CDN $1.00; Process recoveries of Pb 74%, Zn 75%, Au 91%, Ag 80%; Smelter payables of Pb 95%, Zn 85%, Au 96%, Ag 91%; Refining charges of Au US$10/oz, Ag US$0.50/oz; Concentrate freight charges of C$65/t and Smelter treatment charge of US185/t; Mass pull of 5% and 8% concentrate moisture content. 5) The NSR cut-off of CDN$110 per tonne was derived from $75/t mining, $25/t processing and $10/t G&A. 6) AuEq= Au g/t + (Ag g/t x 0.011) + (Pb % x 0.422) + (Zn % x 0.455) 10

Metallurgical Summary Metallurgical flowsheet includes gold (arsenopyrite/pyrite), lead (galena), and zinc (sphalerite) flotation concentrates. Most gold and some silver are recovered into gold/silver Dore from the arsenopyrite/pyrite concentrate after pressure oxidation leaching (POX), or bio-leaching, and cyanidation. Most silver and some gold are recovered from the lead concentrate (Micon Int l Ltd., 2012). According to Micon Int l Ltd. (2012), gold is present in two modes. The majority (80%-90%) occurs as solid solution within the arsenopyrite matrix. The second mode of gold occurrence (10%-20%) is as fracture filling/veinlets in arsenopyrite or as coarse grains locked to gangue or other sulfides. This secondary gold occurrence liberates on grinding, floats with the lead concentrate and is cyanide leachable. The majority of the silver is present as freibergite and is in solid solution with the lead minerals. Metal recoveries to sulfide concentrates are in the order of 98%. Gold and silver extraction from arsenopyrite concentrates treated by pressure oxidation and cyanidation were approximately 90% and 50%, respectively. Extractions for arsenopyrite concentrates treated by bio-oxidation and cyanidation were approximately 90% and 80%, respectively. After accounting for heavy media, flotation and POX leaching losses, including the assumption of no precious metal payables for the zinc concentrate, the overall recoveries of the principal metal credits were calculated at 92% for gold and 90% for silver (Huakan International Mining Inc., NR Jan.17, 2013). 12
