Copper Mountain Mining Announces Q1 2021 Financial Results, Posts Record Quarterly Production, C1 Cash Costs and Gross Profit

HIGHLIGHTS
• Record quarterly production in Q1 2021 of 30.4 million pounds of copper equivalent (comprised of 25.5 million pounds of copper, 8,187 ounces of gold, and 160,484 ounces of silver).
• Record quarterly C1 cash cost for Q1 2021 of US$1.15/lb copper produced, all-in sustaining cost (AISC) of US$1.46/lb copper and all-in cost (AIC) of US$1.71/lb copper.
• Record quarterly revenue for Q1 2021 of $162.2 million, from the sale of 27.5 million pounds of copper, 8,553 ounces of gold and 161,657 ounces of silver, net of pricing adjustments.
• Record gross profit of $96.3 million and net income per share of $0.18.
• Cash and cash equivalents at the end of Q1 2021 of $137.1 million, an increase of $51.5 million from the end of the fourth quarter of 2020 and a $100.9 million increase from the end of the first quarter of 2020.
• Cash flow from operations for Q1 2021 of $79.6 million.
• Subsequent to the quarter:
o The Company closed a US$250 million bond financing to refinance existing debt, enabling the Company to fund its internal growth projects at the Copper Mountain Mine as well as the Eva Copper Project.
o Purchased put options for 28.4 million pounds of copper at a strike price of US$3.75 per pound for the period of May to December 2021, approximately 45-50% of estimated production for that period.

“We started the year in a very strong position achieving record quarterly production for another quarter,” commented Gil Clausen, Copper Mountain’s President and CEO. “Production was higher in the first quarter as we mined mostly from Phase 3, which has higher grade ore. As we move to increase the ratio of ore production from Phase 2 of the main pit, we expect to see grades moderate somewhat. Phase 2 of the main pit has lower mining costs than Phase 3 as we are mining upper benches of ore that are closer to the primary crusher and waste dumps. As a result of our record first quarter and the expected continued strong production throughout the year, we expect production to be in the upper half of our annual production range of 85 to 95 million pounds of copper.”

Mr. Clausen continued, “The Company has a strong cash position, a healthy balance sheet and is generating significant free cash flow. The US$250 million bond financing completed in April allows the Company to retire all of its previous restrictive debt and access 100% of excess cash to fund the organic growth plans of the Company. Our vision is to triple our Company’s annual production rate from 2020 levels in the next five years from the development of our low cost and high ROIC project pipeline. We intend to grow in an environmentally and financially conscious manner. As we begin to execute on our growth plans and in anticipation of any major investment decision, we are mindful of protecting our revenue and margins through mechanisms such as the purchase of put options as we have just done in April. The put options set a floor of $3.75 per pound copper for approximately half of our remaining production for the balance of the year, with all of our production open to the upside on a potentially burgeoning copper market.”

SUMMARY OF OPERATING RESULTS

In Q1 2021, the Copper Mountain Mine produced a record 25.5 million pounds of copper, 8,187 ounces of gold, and 160,484 ounces of silver, as compared to 17.5 million pounds of copper, 6,139 ounces of gold, and 80,016 ounces of silver for Q1 2020. The higher grade ore was the primary driver of the record production in Q1 2021. Average mill feed grade increased to 0.42% Cu during the quarter, as compared to average feed grade of 0.30% Cu in Q1 2020. Mined grade was higher in the first quarter and similar to the grade mined in the fourth quarter of 2020. The 2021 development sequence plan has proportionally more ore coming from Phase 3 of the Main Pit in the first quarter, which has higher grade. Grades and production are expected to moderate for the remainder of the year.

Copper recovery was 80.2% in Q1 2021 as compared to 75.3% in Q1 2020, a normal level of recovery as Q1 2020 production primarily occurred in a lower recovery domain area of the deposit. The mill processed a total of 3.4 million tonnes of ore during the quarter as compared to 3.5 million tonnes in Q1 2020. Mill tonnage was intentionally reduced in Q1 2021 in order to manage the sheer volume of copper concentrate being produced due to the higher head grade. The Company plans to invest in additional filtration capacity in order to maintain full throughput during periods of high grade production. Mill availability averaged 93.9% for Q1 2021 as compared to 92.3% in Q1 2020.

To date there have been no material interruptions to the Company’s operations, logistics and supply chains as a result of the COVID-19 pandemic. Enhanced health and safety protocols continue to be implemented and monitored.

C1 cash cost per pound of copper produced for Q1 2021 was US$1.15, as compared to US $2.01 in Q1 2020. The decrease in cost per pound in Q1 2021 was the result of higher production and larger by-product credits for the gold and silver produced in Q1 2021 as compared to Q1 2020. Higher by-product credits were the result of improved precious metal prices and greater gold and silver production in Q1 2021 as compared to Q1 2020.

All-in sustaining cost per pound of copper produced (AISC) was US$1.46 in Q1 2021, as compared to US$2.14 in Q1 2020. The low AISC carries forward from the low C1 cost per pound with the addition of $10.1 million in sustaining capital, lease and applicable administration expenditures in Q1 2021 as compared to $3.1 million in Q1 2020. The increase is largely a result of higher sustaining capital of $6.4 million and lease payments of $2.7 million. Sustaining capital was in line with budget but higher than the same quarter last year as the Company completed the installation of new water management and pump back systems in the quarter. Increased lease costs were a result of four new haul truck leases that were entered into in late 2020.

Total all-in cost per pound of copper produced (AIC), net of credits, for Q1 2021 was US$1.71, as compared to US$2.47 in Q1 2020. The low AIC carries forward from the low AISC with the addition of $8.0 million in deferred stripping as compared to $7.4 million of deferred stripping in Q1 2020, as the Company commenced initial development of the phase 4 pushback of the main pit during the quarter. Sustaining capital is expected to decrease throughout the year from Q1 2021 levels and the Company reaffirms its estimates provided for 2021 of US$9.0 million. No low-grade stockpile mining costs were incurred in Q1 2021 as compared to $0.3 million of low-grade stockpile costs in Q1 2020.

The significant decrease in C1, AISC, and AIC recognized in Q1 2021 as compared to past quarters was a result of the Company’s strong copper production, cost savings initiatives and operating efficiencies at the Copper Mountain mine, supplemented by an increase in precious metals production and prices for Q1 2021.

SUMMARY OF FINANCIAL RESULTS

In Q1 2021, revenue was $162.2 million, net of pricing adjustments and treatment charges, compared to $49.6 million in Q1 2020. Revenue increased significantly during the quarter as a result of increased sales and higher metal prices. Q1 2021 revenue is based on the sale of 27.5 million pounds of copper, 8,553 ounces of gold, and 161,657 ounces of silver and on an average realized copper price of US$3.90 per pound. Q1 2021 sales were higher than Q1 2021 production levels as a result of slightly higher concentrate inventory levels at the end of the last quarter. The Company expects sales to more closely match production going forward.

Revenue was also higher due to a positive mark to market and final adjustment on concentrate sales of $15.4 million as compared to a negative mark to market and final adjustment of $17.1 million for Q1 2020, a differential of approximately $32.5 million. Q1 2021 revenue before the mark-to-market adjustment is $146.7 million as compared to $66.7 million for Q1 2020.

Cost of sales in Q1 2021 was $65.9 million as compared to $64.5 million in Q1 2020. Mine operating costs are net of $9.2 million of mining costs allocated to deferred stripping in Q1 2021 and $7.4 million in Q1 2020.

The Company reported net income of $52.1 million in Q1 2021 as compared to net loss of $43.4 million in Q1 2020. The variance in the net income for Q1 2021, as compared to the net loss for Q1 2020, was a result of several items including:

• Higher revenue in Q1 2021 as a result of:
o Higher realized copper, gold and silver metal prices of 51%, 13% and 55%, respectively, as compared to Q1 2020.
o Higher quantities of copper, gold and silver sold of 54%, 34% and 106% respectively, as a result of high concentrate levels at the end of the previous quarter.
o A $15.4 million positive mark to market adjustment from provisional pricing on concentrate sales compared to a $17.1 million negative mark to market adjustment for Q1 2020, a differential of $32.5 million.
• The inclusion of a non-cash unrealized foreign exchange gain of $3.2 million in Q1 2021 as compared to a non-cash unrealized foreign exchange loss of $26.8 million in Q1 2020, a differential of $30.0 million, which is primarily related to the Company’s debt that is denominated in US dollars.

On adjusted basis, the Company recorded a net income of $33.4 million in Q1 2021, or $0.16 on a per share basis, compared to $1.4 million in Q1 2020, or $0.01 on a per share basis.

PROJECT DEVELOPMENT UPDATE
The Company continued to progress the Ball Mill 3 Expansion Project at the Copper Mountain Mine with construction well advanced. The Ball Mill 3 Expansion Project is designed to increase mill throughput to 45,000 tonnes per day from 40,000 tonnes per day and improve copper recovery as a result of achieving a finer grind of ore. Demolition has been completed in the area where the third ball mill is to be installed and the raft foundation has been poured on top of lean concrete and bedrock. The Company is currently erecting forms and installing rebar for the mill pier foundations, with concrete expected to be poured in April. The Ball Mill 3 Expansion Project is on track for commissioning in the third quarter of 2021.

EXPLORATION UPDATE

Canada
The 2021 exploration program at the Copper Mountain Mine began in early March. The program consists of exploration drilling designed to expand resources and reserves in the Copper Mountain North and New Ingerbelle deposits. The total program for 2021 consists of approximately 20,000 metres of diamond drilling.

Australia
The exploration team mobilized to Cloncurry in mid-March and are preparing for an extensive field program aimed at discovering new deposits within some of the high potential areas within the Company’s large land holdings. Detailed geochemical and geophysical surveys will be used to target exploration drill holes in some areas, whereas other areas to be drilled will be following up on previous drill results. The drill program will focus primarily on copper and copper-gold targets. The 2021 exploration program consists of 6,000 metres of RC drilling and 1,200 metres of diamond drilling.

OUTLOOK
As a result of strong Q1 2021 production results, the Company expects to achieve the upper half of its annual guidance range of 85 to 95 million pounds of copper. The Company also expects grade to moderate from Q1 2021 and Q4 2020 levels, with the fourth quarter of 2021 production planned to be higher due to the commissioning of the Ball Mill 3 Expansion Project. The Company expects all-in cost (AIC) to remain low and reaffirms annual AIC guidance of US$1.80 to US$2.00 per pound.
