Capstone Beats 2019 Cost Guidance, Commences PV3 Optimization Study

(All amounts in US$ unless otherwise specified)

Capstone Mining Corp. (“Capstone” or the “Company”) (TSX:CS) announced its production and financial results for the three months (“Q4 2019”) and year ended December 31, 2019. Copper production for 2019 totaled 153.4 million pounds of copper at consolidated C1 cash costs¹ of $1.78 per pound. For full financial and operational results, refer to Capstone’s 2019 Management’s Discussion and Analysis and Consolidated Financial Statements (“MD&A and Financial Statements”).

“We are pleased to announce that we finished 2019 above the mid-range on production guidance and below the bottom end of the guidance range on cash costs,” said Darren Pylot, President and CEO of Capstone. “Our two operations have near-term growth that combined will lead to a 20% boost to production and a 10% reduction in costs by 2021, but we are not stopping there. Today we are announcing a PV3 Optimization Study at Pinto Valley that will look at a number of low capital, quick payback projects aimed at debottlenecking various areas of the operation to enhance overall performance at Pinto Valley. The previously announced $15 million secondary crushers and ball mill shells replacement, scheduled in 2020, will be the first of many expected projects that collectively will debottleneck the operation. Overall, we believe there is room to push copper production significantly higher and costs lower at Pinto Valley.”

Mike Wickersham, General Manager of Pinto Valley Mine, said, “During the month of November, we strategically advanced maintenance on key areas of the crushing plant to set up for an operational test in December, designed to push throughput levels beyond previously understood limits. From this, Pinto Valley achieved 18 days above 60,000 tonnes per day (“tpd”), an all-time average weekly throughput record of 63,517 tpd and an all-time daily tonnage record of 70,334 tpd. We have launched a PV3 Optimization Study to assess how we can sustainably achieve performance like this. The report will be shared in the second half of 2020.”

Mr. Pylot continued, “2019 was a transformational year for Cozamin and it was due to exploration excellence, as we have announced some of the best drill results in its 13 year history for Capstone. Cozamin has always been the cornerstone cash flow asset for the Company and its current exploration success will ensure it stays that way for at least the next 10 years.”

Q4 2019 HIGHLIGHTS AND SIGNIFICANT ITEMS

• Capstone achieves higher than the mid-point of 2019 production guidance and delivers costs below the low end of C1 cash costs¹ guidance. 2019 production of 153.4 million pounds of copper is in the top half of the guidance range of 145-160 million pounds and consolidated C1 cash costs¹ of $1.78 per payable pound of copper is lower than guidance of $1.80-$2.00 per payable pound.
• Q4 2019 copper production of 35.4 million pounds and C1 cash costs¹ of $1.97 per payable pound produced. Copper sales were higher at 40.3 million pounds due to the inventory drawdown at Pinto Valley. Pinto Valley Q4 2019 copper production was impacted by downtime in the fine crushing plant which enabled the Company to perform maintenance upgrades and then perform an operational test in December, see below.
• In December, Pinto Valley conducted a test to push throughput levels a minimum of 10% higher and was able to achieve 18 days in excess of 60,000 tonnes per day (“tpd”) and reached an all-time record daily tonnage of 70,334 tpd on December 21, 2019. The objective of the test was to generate a list of bottlenecks that could potentially be overcome with low capital projects or operational improvements. A PV3 Optimization report is expected to be announced in H2 2020 along with a PV4 100,000+ tpd expansion study. Refer to the Corporate Update section for details.
• Q4 2019 net income of $13.4 million from continuing operations (Q4 2018 – net loss from continuing operations of ($15.2) million), which was positively impacted by higher sales volumes and a lower income tax expense (driven primarily by the recognition of $23.2 million of deferred tax assets associated with previously unrecognized corporate tax pools).
• Q4 2019 operating cash flow before changes in working capital of $20.3 million (Q4 2018 of $11.2 million).
• The Company achieved its goal of removing $27.5 million of annualized costs out of the business. Pinto Valley delivered an additional $2.5 million in sustainable annualized cost savings in Q4 2019 totalling $15 million in reductions on a full year basis, which is a reduction in overall site operating costs of approximately $0.80 per tonne milled. Refer to the Corporate Update section for details.
• In Q4 2019, the Board approved the first phase of the PV3 Optimization study with a $15 million capital investment to improve mill reliability and overall performance at Pinto Valley. The expected result is increased and sustainable throughput to between 56,000 to 57,000 tpd in 2021 and beyond. The one-year payback is calculated based on expected higher throughput, reduced maintenance and power costs, as well as increased copper recovery associated with improved copper mineral liberation prior to flotation.
• In Q4 2019, Cozamin’s raisebore project Phase 1 was completed two months ahead of schedule. Ventilation to the upper section of the one-way ramp immediately improved when the reaming head broke through to surface in December 2019. The project is expected to be completed in early 2020.
• Cozamin has announced the results from 150 holes of a 200 hole 2019/2020 infill drilling program, aiming to double the current reserve base. Positive drill results pointing to potentially higher grades and wider intercepts than in the current reserve, as well as an expanded high grade resource, were released on November 5, 2019, December 2, 2019 and January 16, 2020. Mineral Resource and Mineral Reserve estimates will be updated in late 2020.

CORPORATE UPDATE
Cost Reduction Program
Capstone has achieved its cost reduction target range of $25 to $30 million, using 2018 as a baseline. The Company has now removed $27.5 million of costs out of the business with $15 million in savings at Pinto Valley, resulting in a decrease in site operating costs of approximately $0.80 per tonne milled. Other areas of sustainable annualized savings include $3.5 million related to the new revolver terms and improved cash management, $4 million from downsizing of corporate administration and $5 million related to the disposition of Minto.

Cozamin: Near-Term Expansion Update
Development work on the one-way ramp system at Cozamin to debottleneck mine haulage continues on budget and on schedule for completion by the end of 2020. The concurrent development of the raisebore to improve ventilation in the southeast part of the mine is ahead of schedule and is expected to be completed in early 2020. Phase 1 completed ahead of schedule when the reaming head broke through to surface in December 2019, and immediately improved ventilation to the upper section of the new one-way ramp. Once these two underground expansion projects are completed, Cozamin’s annual production for 2021 and beyond is expected to increase to approximately 50 – 55 million pounds of copper and 1.5 million ounces of silver.

Cozamin: Doubling the Mine Life
The 2019/2020 infill drilling program is progressing well and is approximately two months ahead of schedule, allowing flexibility to add more holes than originally planned. The drill program is aiming to upgrade Inferred Mineral Resources to Indicated category and subsequent conversion to Mineral Reserves to support doubling the mine life. Positive drill results pointing to higher grades and wider intercepts than in the current Mineral Reserve were released on November 5, 2019, December 2, 2019 and January 16, 2020. Mineral Resource and Mineral Reserve estimates are expected to be updated in late 2020.

During Q4 2019, Cozamin started drilling into the Portree claimblock (“Portree”) it acquired earlier in the year. Prior to this, Portree was an untested inlier within Cozamin’s land position covering the Mala Noche Footwall Zone (“MNFWZ”) area. Portree is surrounded by high grade Inferred Mineral Resources that future drilling is expected to increase to Indicated categorization. Mining has already started within the newly acquired Portree claim.

Pinto Valley: Crushing Plant Modernization
In Q4 2019, the Board approved a $15 million capital project as part of the PV3 Optimization study to improve mill reliability and overall performance at Pinto Valley. The expected result is for throughput to reliably achieve between 56,000 to 57,000 tpd in 2021. The one-year payback is calculated based on expected higher throughput, reduced maintenance and power costs, as well as increased copper recovery associated with improved copper mineral liberation prior to flotation. Pinto Valley’s 2020 guidance of between 110 to 120 million pounds of copper production accounts for scheduled downtime for secondary crusher and ball mill shell installations as part of this capital project.

Pinto Valley: PV3 Optimization & PV4 Expansion
Capstone is focused on incremental low capital investments and operational improvements to increase the mill tonnage beyond the 56,000 to 57,000 tpd, noted above. An operational test conducted in December 2019, aimed at pushing throughput levels up 15% to 60,000 tpd or more, was successfully executed. The test realized an all-time daily throughput record of 70,334 tpd and an all-time weekly throughput record of 63,517 tpd. Data from this test is currently being studied to determine what is the peak capacity run rate tied to a low capital expansion of Pinto Valley. The focus of the PV3 Optimization report is to maximize production by systematically debottlenecking the operation with a series of quick payback projects. All required permits are in place to operate at levels up to 79,500 tpd.

Preliminary work on the Pinto Valley future expansion to 100,000+ tpd (“PV4 Expansion”) continues, with an update expected in H2 2020. The study is focused on evaluating potential scenarios to take advantage of the one billion tonnes of Mineral Resources not currently scheduled in the current mine plan pit shell (“PV3”).

Santo Domingo Project Progress
The Santo Domingo project is now “shovel-ready” as Capstone has obtained all permits and approvals for the start of construction from the Chilean authorities. An updated technical report that will include the opportunity to recover battery-grade cobalt is expected before the end of Q1 2020. Capital expenditures for the fully permitted project will be kept to a minimum in 2020 to preserve the optionality of the project as we continue the strategic process to right size or monetize Capstone’s ownership.

Board Appointment
Capstone is also announcing the appointment of SeungWan Shon to the Company’s Board of Directors as KORES’ nominee, effective February 12, 2020. Min Geol Ryu will be stepping down from the Board of Directors, also effective February 12, 2020.

Mr. Shon currently leads KORES’ Metals Team, managing overseas copper projects. Mr. Shon has been with KORES since 2001 and held numerous positions which include Mine Manager, Senior Manager of KORES Corporate Partnership Team and Senior Manager of the Exploration Team for Nonmetal Mineral Deposits in South Korea. Mr. Shon holds a Master of Science in Geology from Kyungpook National University, Korea.

PRODUCTION RESULTS
Refer to Capstone’s 2019 MD&A and Financial Statements for detailed operating results.

Consolidated
For the year ended December 31, 2019, C1 cash costs¹ of $1.78 per pound produced were lower than 2018 as well as lower than the guided range. Production was in the top half of the guidance range.

The realized copper price in Q4 2019 of $2.77 per pound was higher than the LME average of $2.67 per pound due to four provisionally priced shipments at December 31, 2019, which were priced at an average of $2.79 per pound. The realized copper price in 2019 was $2.71 per pound, compared to $2.87 per pound in 2018 primarily due to lower gross copper revenue on new shipments of $2.76 per pound in 2019 (2018 was $2.92). Both periods had the same ($0.05 per pound) provisional adjustments on prior shipments.

Pinto Valley Mine
2019 C1 cash costs¹ of $2.05 per pound were lower than 2018, primarily due to the cost reduction program which lowered site operating costs to $216 million versus $231 million (including capitalized stripping costs). Copper production in 2019 was similar to 2018.

In Q4 2019, C1 cash costs¹ of $2.35 per pound were higher than Q4 2018, driven by lower production. Pinto Valley undertook downtime in November to perform maintenance in the fine crushing plant prior to conducting an operational test in December, aimed at running at significantly higher throughput rates. By pushing the operational limits at Pinto Valley, the information from this test is currently being analyzed to generate a number of debottlenecking projects from the mine through the mill. As a result of this test, Pinto Valley delivered 18 days in excess of 60,000 tpd in December, culminating in an all-time record day of 70,334 tpd and an all-time weekly record of 444,622 tonnes (~63,517 tpd average). The focus now will be to deliver a PV3 Optimization Study in H2 2020 that will identify low capital, high impact and quick payback projects to systematically debottleneck the entire operation so that Pinto Valley can perform at sustainably higher rates while maximizing recoveries, production and minimizing costs.

Cozamin Mine
C1 cash costs¹ increased in Q4 2019 and 2019 compared with the same periods last year. This increase was primarily driven by an increase in development in 2019 (11,050 metres versus 9,934 metres) as the mine builds an inventory of areas to be available for longhole stoping in preparation to support increased mining rates planned to start in 2021. Production in 2019 was consistent with 2018 results.

FINANCIAL OVERVIEW
