Alternative Performance Measures“1 cash cost”, “cash cost”, “adjusted EBITDA”, “operating cash flow before changes in working capital” and “net debt” are Alternative Performance Measures. Alternative performance measures are furnished to provide additional information. These non-GAAP performance measures are included in this presentation because these statistics are key performance measures that management uses to monitor performance, to assess how the Company is performing, to plan and to assess the overall effectiveness and efficiency of mining operations. These performance measures do not have a standard meaning within IFRS and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. These performance measures should not be considered in isolation as a substitute for measures of performance in accordance with IFRS.

Reserve Assumptions
NI43-101 RESERVE NOTES:1. Tucker Jensen, P.Eng., Senior Mining Engineer at Capstone Mining Corp., is the Qualified Person for this Cozamin Mineral Reserve update. Disclosure of the Cozamin Mine Mineral Reserves as of October 24, 2018 was completed using fully diluted mineable stope shapes generated by the Maptek Vulcan Mine Stope Optimizer software and estimated using the 2016 MNV resource block model created by J. Vincent, P.Geo., formerly of Capstone Mining Corp and the 2018 MNFWZ resource block model created by Garth Kirkham, P.Geo., FGC. 2. Mineral Reserves are reported at a US$50/t net smelter return ("NSR") cut-off using the NSR275 formula: ($50.707*%Cu + 0.366*Ag ppm + 7.276*Zn%)*(1-NSRRoyalty%) based on metal price assumptions (in US$) of Cu = $2.75/lb, Ag = $16.00/oz, Zn = $1.10/lb and metal recoveries of 96.5% Cu, 81% Ag, 44% Zn. Note that zero value was attributed to Pb due to low concentrations. Tonnage and grade estimates include dilution and recovery allowances. The NSR royalty rate applied varies between 1% and 3% depending on the mining concession. All metals are reported as contained.

Resource Assumptions
NI43-101 RESOURCE NOTES:1. Garth Kirkham, P.Geo., FGC, is the independent Qualified Person responsible for the disclosure of Cozamin Mineral Resources. Mineral resources are reported at a cut-off of NSR US$50 using the NSR350 formula: Cu*65.024 + Ag*0.438 + Zn*10.755 + Pb*6.981 based on metal price assumptions (in US$) of Cu = $3.50/lb, Ag = $18.00/oz, Zn = $1.20/lb, Pb = $1.00/lb and metal recoveries of 95% Cu, 78% Ag, 58% Zn, 40% Pb. All contained metals are reported at 100%. Totals may not sum exactly due to rounding.2. The cut-off date for mining activities and drillhole sample data is October 24, 2018.3. Mineral resources are not mineral reserves and do not have demonstrated economic viability.4. Mineral resources are reported inclusive of the mineral reserves.

LEACH TRIAL, NEAR-TERM CATALYST
• Pinto Valley is a perfect test site for leach catalyst due to high chalcopyrite mineralization (~95%) with minimal clay plus SXEW under-capacity
• SXEW ~4 Mlbs/year recent production rate on a 25 Mlbs/year design capacity
• Benchscale testing results positive, pilot results available by year end 2019
• 454 M tonnes of ore placed under leach since 1981, achieving ~30% copper recovery
• Based on preliminary lab testing, possible to improve recovery by ~300 Mlbs additional copper from old leached material
• Additional ~200 Mlbs of contained Cu to be placed by 2024, recovery of 60% potential

Alternative Performance Measures“C1 cash cost”, “cash cost”, “adjusted EBITDA”, “operating cash flow before changes in working capital” and “net debt” are Alternative Performance Measures. Alternative performance measures are furnished to provide additional information.

Disclosure of the Cozamin Mine Mineral Reserves as of December 31, 2017 was completed using fully diluted mineable stope shapes generated by the Maptek Vulcan Mine Stope Optimizer software and estimated using the 2018 MNFW and MNV resource block models completed by Garth Kirkham, P.Geo., FGC, Kirkham Geosystems Ltd. The Reserves are based on a $50/t NSR cut-off. The NSR formula used for the Reserves was based $2.75/lb Cu, $16/lb Ag, $1.10/lb Zn, and metallurgical recoveries of 96.5% Cu, 81% Ag, 44% Zn. The resulting NSR275 formula is ($50.707*%Cu + 0.366*Ag ppm + 7.276*Zn%)*(1-NSRRoyalty%)Note that zero value is attributed to Pb due to low concentrations. Tonnage and grade estimates include dilution and recovery allowances. The NSR royalty rate applied varies between 1% and 3% depending on the mining concession. Contained metals are reported as 100%. Figures may not sum due to rounding. See Capstone’s Annual Information Form for the year ended December 31, 2018 for further information.

Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Mineral Resources are classified according to CIM (2014) guidelines. The Qualified Person for the estimates is Mr. David Rennie, P.Eng., an associate of Roscoe Postle Associates Inc. Mineral Resources for the Santo Domingo Sur, Iris, Iris Norte and Estrellita deposits have an effective date October 31, 2018. Mineral Resources for the Santo Domingo Sur, Iris, Iris Norte, and Estrellita deposits are reported using a cut-off grade of 0.125% CuEq. CuEq grades are calculated using average long-term prices of $3.50/lb Cu, $1,300/oz Au, and $99/dmt Fe. The CuEq equation is: % Cu Equivalent = (Cu Metal Value + Au Metal Value + Fe Metal Value) / (Cu Metal Value per percent Cu). The general equation for metal value is: Metal Value = Grade * Cm * R * (Price – TCRC – Freight) * (100 – Royalty) / 100, were Cm is a constant to convert the grade of metal to metal price units, R is metallurgical recovery, and TCRC is smelter treatment charges and penalties. An assessment of Mineral Resources for the Santo Domingo Sur, Iris, Iris Norte and Estrellita deposits was performedusinga Lerchs–Grossman pit shell that has the following assumptions: pit slopes averaging 45°; mining cost of $1.90/t, processing cost of $7.27/t (including G&A cost); processing recovery of 89% copper and 79% gold; selling price of $3.50/lb copper, $1,300/oz gold and $99/dmt iron concentrate. Rounding as required by reporting guidelines may result in apparent summation differences between tonnes, grade and contained metal content.

Mineral Reserves are reported as constrained within Measured and Indicated pit designs and supported by a mine plan featuring variable throughput rates and cut-off optimization. The pit designs and mine plan were optimized using the following economic and technical parameters: metal prices of $3.00/lb Cu, $1,290/oz Au and $100/dmt of Fe concentrate; recovery to concentrate assumptions of a maximum of 93.4% for Cu and 60.1% for Au, with magnetite concentrate recovery varying on a block-by-block basis; copper concentrate treatment charges of $80/dmt, $0.08/lb of Cu refining charges, $5.0/oz of Au refining charges, $33/wmt and $20/wmt for shipping Cu and Fe concentrates respectively; wasteminingcostof $1.75/t, mining cost of $1.75/t ore, and process and G+A costs of $7.53/t processed; average pit slope angles that range from 37.6° to 43.6°; a 2% royalty rate assumption, and an assumption of 100% mining recovery. Rounding as required by reporting guidelines may result in apparent summation differences between tonnes, grade and contained metal content.
