- Mineral resource copper cut-off grades of 0.68% copper for underground mineral resources and 0.18% for open pit mineral resources. Mineral resources have been estimated using ordinary kriging inside 5m by 5m by 5m block sizes. The mineral resource estimates were prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards for Mineral Resources and Mineral Reserves, adopted by the CIM Council on May 10, 2014 (the “CIM Standards”), and the CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines, adopted by CIM Council on November 23, 2003 (the ‘CIM Guidelines”), using geostatistical and/or classical methods, plus economic and mining parameters appropriate to the deposit. Effective date of the mineral resource estimate varies by deposit. Please see “Technical and Scientific Information” near the end of this news release for additional information on the stated mineral resources.
- Mineral reserve estimates were prepared in accordance with the CIM Standards and the CIM Guidelines, using geostatistical and/or classical methods, plus economic and mining parameters appropriate for the deposit. Mineral reserves are based on a long-term copper price of US$2.75 per pound (“lb”), and a USD:BRL foreign exchange rate of 3.20. Mineral reserves are the economic portion of the Measured and Indicated mineral resources. Mineral reserve estimates include mining dilution at zero grade. Mining dilution and recovery factors vary for specific mineral reserve sources and are influenced by factors such as deposit type, deposit shape, stope orientation and selected mining method. Please see “Technical and Scientific Information” near the end of this news release for additional information on the stated mineral reserves.
Mineral resources which are not mineral reserves do not have demonstrated economic viability.
UPDATED PRODUCTION PLAN
The Company’s updated production plan, prepared in conjunction with the mineral resource and mineral reserve update, provides a solid platform from which to grow copper production, improve operating efficiencies, and reduce capital and operating costs in the future as new deposits are discovered and developed within the Curaçá Valley. The new mine plan, with stabilized mill feed and copper grades, provides greater flexibility to better utilize the Caraíba Mill’s installed capacity of 3.2 million tonnes per annum, as well as continue to evaluate expansion opportunities to return the mill to its original installed capacity of 5.5 million tonnes per annum.
The table below outlines the updated production plan for the Vale do Curaçá Property. The plan is centered upon providing the Caraíba Mill with a more consistent plant feed averaging 2.1 million tonnes producing, on average, approximately 41,000 tonnes of copper in concentrate per annum over the next five years.

MINERAL RESOURCE & RESERVE GROWTH
The following section discusses the updated mineral reserve and resource estimates as they relate to each of the three mineral districts of the Vale do Curaçá Property. Detailed information with respect to tonnes, grade and contained copper for the mineral reserve and resource estimates for each mineral district can be found at the end of this news release. Relative comparisons to 2017 refer to the 2017 Technical Report.
Pilar
The amount of contained copper within the Measured and Indicated mineral resources increased by 40% in the Pilar mine. This increase in contained copper was primarily attributable to increases in the Deepening Zone (228 thousand tonnes (“kt”) contained copper in 2017 vs. 287kt contained copper in 2018), new resources from the north extension zone (increase of 15kt contained copper) and a portion of the West Limb defined by historical drilling (increase of 61kt contained copper).
Infill and extensional drilling at the Pilar mine resulted in a 60% increase in the amount of copper within the Proven and Probable mineral reserve estimate. The newly identified West Limb contributed an increase of 44kt of contained copper to the mineral reserves, while infill and extension drilling in the Deepening, South Extension, and P1P2NE zones collectively contributed an additional 27kt of contained copper (see Figure 1 for additional detail on resource areas of the Pilar mine). No material change occurred in the Proven and Probable mineral reserve estimate in the Deepening Zone.
During the upcoming year, infill drilling will focus on converting newly identified mineral resources to reserves, particularly within the Deepening Zone and West Limb, while the exploration program will continue to expand mineral resources within the West Limb and downdip extensions to the Deepening Zone.
Vermelhos
Contained copper within the Measured and Indicated mineral resource estimate increased by 68% at Vermelhos. This increase is attributable to a new area of mineral resource (“Vermelhos West”), which was defined by historic drilling but only recently re-evaluated (increase of 49kt of contained copper), along with expansions of the UG1 and UG2 mining areas defined as part of the Vermelhos infill drill program. Increases in the main portion of the Vermelhos underground mine, including UG1 and UG2 mining areas, totaled 34kt of contained copper within the Measured and Indicated mineral resources (see Figure 2 for additional detail on resource areas of the Vermelhos Mine).
Vermelhos West is a zone of mineralization located approximately 1 kilometer to the north, north-east of, and on trend with, the Vermelhos mine. The Measured and Indicated mineral resources extend from near-surface to a depth of approximately 200 meters, the depth of the historic drill program. The deposit remains open at depth, and additional work is planned to determine the relationship between mineralization in this zone and that of the main orebodies of the Vermelhos mine.
Infill and extension drilling within the main Vermelhos mine resulted in a 24% increase in the Proven and Probable mineral reserves (100kt of contained copper in 2017 vs. 125kt of contained copper in 2018). In addition, 8kt of contained copper was added to the Proven and Probable mineral reserves from the Vermelhos West.
During the upcoming year, drilling at the Vermelhos mine, and Vermelhos West, will focus on converting mineral resources to reserves while continuing to test extensions of known mineral resources and evaluating new targets to depth.
Surubim
Contained copper within the Measured and Indicated mineral resource estimate at the Surubim mine increased by 1,208% (4kt of contained copper in 2017 vs. 47kt of contained copper in 2018). The increase in contained copper is attributable to expansion of resources being mined within the current operating open pit along with extensions below the pit, as well as satellite zones defined adjacent to the mine (see Figure 3 for additional detail on resource areas of the Surubim mine).
In conjunction with the increase in contained copper within the Measured and Indicated mineral resources, there was an 885% increase in the contained copper within the Proven and Probable mineral reserves at the Surubim mine (2kt of contained copper in 2017 vs. 20kt of contained copper in 2018). The increase in Proven and Probable mineral reserves was attributable primarily to downdip extensions of the reserves currently being mined from the Surubim open pit mine. These downdip extensions will be mined in the future via a decline to be developed from the bottom of the current open pit.
During the course of the next year, drilling will focus on continuing to define underground extensions to mineralization along with further defining mineral resources in satellite zones adjacent to, and on trend with, the open pit mine.
REGIONAL EXPLORATION PROGRAM UPDATE
The Company’s airborne geophysical survey comprised of both electromagnetic and gravity systems has now been completed over the planned survey area. Data processing is nearing completion and prioritization of initial drill targets is currently underway.

Non-IFRS Measures
The Company utilizes certain non-IFRS measures, including C1 cash cost of copper produced, which are not measures recognized under IFRS. The Company believes that these measures, together with measures determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company. Non-IFRS measures do not have any standardized meaning prescribed under IFRS, and therefore they may not be comparable to similar measures employed by other companies. The data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.
C1 Cash cost of copper produced (per lb) is the sum of production costs, net of capital expenditure development costs and by-product credits, divided by the copper pounds produced. C1 cash costs reported by the Company include treatment, refining charges, offsite costs, and certain tax credits relating to sales invoiced to the Company’s Brazilian customer on sales. By-product credits are calculated based on actual precious metal sales (net of treatment costs) during the period divided by the total pounds of copper produced during the period. C1 cash cost of copper produced per pound is a non-IFRS measure used by the Company to manage and evaluate operating performance of the Company’s operating mining unit, and is widely reported in the mining industry as benchmarks for performance, but does not have a standardized meaning and is disclosed in addition to IFRS measures.
QUALITY ASSURANCE / QUALITY CONTROL
Current QA/QC Program
The Company is currently drilling underground with core drill rigs using a combination of owned and third-party contracted drill rigs. During the period from June 2017 to August 2018 third party drill rigs were operated by DrillGeo Geologia e Sondagem Ltda., Layne Christensen Co. and Major Drilling, all of whom are independent of the Company. Drill core is logged, photographed and split in half using a diamond core saw at MCSA’s secure core logging and storage facilities. Half of the drill core is retained on site and the other half-core is used for analysis, with samples collected on one-meter sample intervals unless an interval crosses a geological contact. Reverse circulation cuttings are split at the drill rig using one-meter sample intervals. All sample preparation is performed in MCSA’s secure on-site laboratory. Total copper is determined using a nitric-hydrochloric acid digestion and Atomic Absorption Spectrometry (“AAS”) and/or Titration. Oxide copper values are determined using sulfuric acid digestion followed by AAS. All recent sample results have been monitored through a QA/QC program that includes the insertion of certified standards, blanks, and pulp and reject duplicate samples. Regular check-assays are submitted to ALS Brasil LTDA’s facility located in Vespasiano, Minas Gerais, Brazil, at a rate of approximately 5%. ALS Brasil LTDA is independent of the Company.
Historic Database QA/QC Validation
Samples that were analyzed prior to the implementation of MCSA’s current QA/QC program in 2007 have been subjected to the same quality control tools used currently to allow for an evaluation of the accuracy and precision of the grades that were obtained. Based on the demonstrated quality associated with the current sampling procedures and the post-2007 performance of MCSA’s laboratory, which is evaluated through daily QA/QC campaigns, MCSA conducted a post mortem QA/QC analysis, with the aim of validating the samples that were analyzed before the QA/QC program was effectively implemented. The post mortem QA/QC analysis involved re-analyzing a minimum of 10% of the total number of samples with no corresponding QA/QC data to validate the historic assays. Please refer to the 2017 Technical Report for additional information related the post mortem QA/QC analysis.

CAUTIONARY NOTES REGARDING MINERAL RESOURCE AND RESERVE ESTIMATES In accordance with applicable Canadian securities regulatory requirements, all mineral reserve and mineral resource estimates of the Company disclosed or incorporated by reference in this news release have been prepared in accordance with NI 43-101 and are classified in accordance with the CIM Standards.
Mineral resources which are not mineral reserves do not have demonstrated economic viability. Pursuant to the CIM Standards, mineral resources have a higher degree of uncertainty than mineral reserves as to their existence as well as their economic and legal feasibility. Inferred mineral resources, when compared with Measured or Indicated mineral resources, have the least certainty as to their existence, and it cannot be assumed that all or any part of an Inferred mineral resource will be upgraded to an Indicated or Measured mineral resource as a result of continued exploration. Pursuant to NI 43-101, Inferred mineral resources may not form the basis of any economic analysis. Accordingly, readers are cautioned not to assume that all or any part of a mineral resource exists, will ever be converted into a mineral reserve, or is or will ever be economically or legally mineable or recovered.
