“Our operations delivered solid third quarter operating performance against a challenging macroeconomic backdrop that resulted in compressed operating margins during the period,” said David Strang, Chief Executive Officer. “While near-term global economic conditions remain dynamic, we are well-positioned with an experienced team, high-quality operations and a solid balance sheet to continue making progress on our strategic growth initiatives.

“At our Tucumã Project, road upgrades and site drainage are now complete ahead of the rainy season, and our mining contractor mobilized to site and commenced pre-stripping activities and waste rock dump construction during the quarter. All activities on site are advancing in- line with the Feasibility Study schedule. At our Caraíba Operations, shaft civil work, raise- boring and underground development related to our Pilar 3.0 initiative are progressing well, and an updated life-of-mine production plan reflecting the integration of Project Honeypot has also been finalized.

“Despite strong operating performance and successful project execution during the period, our operating costs remain higher than we had forecasted at the beginning of the year due to inflationary pressures and the higher allocation of copper sales to international customers that negate some of the tax benefits we receive when we sell to our domestic customer. As we look ahead to the fourth quarter, we expect to be in line with our revised full-year operating cost guidance but acknowledge we are tracking towards the higher end of the range as a result of these impacts.

“While, like our peers, we continue to navigate challenging near-term market conditions, we remain focused on advancing our growth strategy in anticipation of an unprecedented outlook for copper. The timing of our growth initiatives, now well underway at Tucumã and Caraíba, continues to align well with an expected surge in copper demand that is projected to far outpace supply in the years ahead.”

THIRD QUARTER REVIEW

• Mining & Milling Operations
  • The Caraíba Operations processed 720,725 tonnes of ore grading 1.68% copper, producing 11,189 tonnes of copper in concentrate during the quarter after metallurgical recoveries of 92.2%.
  • The Xavantina Operations processed 42,747 tonnes of ore grading 8.55 grams per tonne gold, producing 10,965 ounces of gold after metallurgical recoveries of 93.3% and 7,487 ounces of silver as a by-product.
• Organic Growth Projects
  • At the Tucumã Project, engineering, contracting efforts and construction activities continued to progress during the quarter.
    • Critical path earthworks, site drainage and road upgrades are finished. Mine pre-stripping, waste and tailings dump construction, and plant site earthworks are underway. Total project engineering and construction are approximately 40% and 8% complete, respectively, on-track with the Feasibility Study schedule;
    • Approximately 30% of planned capital expenditures were under contract as of quarter-end and within 10% of pre-contingency Feasibility Study estimates; and,
    • Approximately 80% of Feasibility Study capital expenditures have now been contracted or are in various stages of tendering or negotiation. Based upon prevailing foreign exchange rates, labour costs and diesel prices, and subject to final contract negotiations, these expenditures are currently forecast to be within 12% of pre-contingency Feasibility Study estimates.
  • The Company continued to advance its Pilar 3.0 initiative, comprised of several projects that together are expected to enable the creation of a two-mine system at the Pilar Mine. These projects include (i) Project Honeypot, an engineering initiative focused on recovering higher-grade material in the upper levels of the Pilar Mine, (ii) construction of a new external shaft to access the Deepening Extension Zone, and (iii) an expansion of the Caraíba Mill to 4.2 million tonnes per annum.
    • Incorporation of Project Honeypot into the Caraíba strategic life-of-mine production plan was completed subsequent to quarter-end and is expected to be released ahead of the Company’s Annual Operational, Project and Exploration Update on November 8, 2022;
    • Construction of the new external shaft is progressing well with physical completion currently at approximately 10% with approximately 30% of planned capital expenditures under contract as of quarter-end; and,
    • Caraíba Mill expansion is advancing as planned with the ball mill installation contract finalized during the quarter.

• Exploration Highlights
  • In early 2022, the Company formed a dedicated nickel exploration team to accelerate the identification and testing of nickel targets throughout the Curaçá Valley. This effort resulted in the announced discovery of a new nickel sulphide system, known as the “Umburana System”, located approximately 20 kilometers from the Caraíba processing facilities. The system, which has an initial strike length of five kilometers, remains open in all directions and is highlighted by multiple surface expressions of nickel mineralization. Drilling of additional targets within the system remains ongoing with four dedicated drill rigs. For additional information on the Umburana System, including drill results, please see the Company’s press release dated September 29, 2022.
  • Exploration at the Tucumã Project during the quarter was focused on extensional drilling of high-grade mineralization to depth in the south and southwestern portions of the deposit, beneath the designed pit shell.
  • Exploration activities at the Xavantina Operations during the quarter continued to focus on testing extensions of the Matinha and Santo Antônio veins. Step-out drilling continues to confirm thick, high-grade extensions at depth within the Santo Antônio vein, which remains open.
  • Highlights from these exploration programs will be announced as part of the Company’s Annual Operational, Project and Exploration Update planned for November 8, 2022.

2022 GUIDANCE^(*)

The Company is reaffirming its full-year production guidance as well as its revised 2022 operating cost and capital expenditure guidance. At the Caraíba Operations, copper production in Q4 2022 is expected to be similar to Q3 2022 production levels. At the Xavantina Operations, the Company also expects to achieve similar Q4 2022 gold production levels relative to Q3 2022, resulting from higher anticipated gold grades and lower expected tonnes processed.

Due primarily to a higher allocation of concentrate sales to the international market and the continued influence of inflation on the cost of key consumables, C1 cash costs at the Caraíba Operations are trending towards the high-end of the guidance range of $1.20 to $1.35 per pound of copper produced. At the Xavantina Operations, costs are trending towards the low- end of the full-year C1 cash cost guidance range of $600 to $700 per ounce of gold produced and the high-end of the 2022 AISC range of $1,000 to $1,100 per ounce of gold produced.

2022 PRODUCTION AND COST GUIDANCE^(*)

The Company’s cost guidance for 2022 assumes a USD:BRL foreign exchange rate of 5.30, a gold price of $1,725 per ounce and a silver price of $20.00 per ounce for Q4 2022.

Reconciliation of Non-IFRS Measures

Financial results of the Company are presented in accordance with IFRS. The Company utilizes certain alternative performance (non-IFRS) measures to monitor its performance, including C1 cash cost of copper produced (per lb), C1 cash cost of gold produced (per ounce), AISC of gold produced (per ounce), EBITDA, adjusted EBITDA, adjusted net income attributable to owners of the Company, adjusted net income per share, net (cash) debt, working capital and available liquidity. These performance measures have no standardized meaning prescribed within generally accepted accounting principles under IFRS and, therefore, amounts presented may not be comparable to similar measures presented by other mining companies.
