MUX McEwen Mining Inc

McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) reports its third quarter (Q3) results for the period ended September 30th, 2022.

“This year has been much better than the previous three! While we still have issues to resolve, such as increasing our treasury by producing more ounces at a lower cost, we can clearly see a brighter future. At the Fox Complex, where we have had a history of high operating cost/oz we are making good progress reducing our cost. I am pleased to say that in Q3 our cash cost/oz at Fox fell to $774, our lowest since mid-2018. This is well below the industry average. Our next important area to improve at Fox is the process plant (mill). Specifically, we need to increase the throughput because our mine is now producing more ore than our mill can process. As a result, we have a large surface stockpile of ore equivalent to more than two months of production.

At Gold Bar, we are looking forward to starting to mine our Gold Bar South (GBS) deposit this quarter. We are expecting to have a much lower cost/oz than our YTD cost because we will be mining higher grade ore at GBS, with half the strip ratio and no problematic carbonaceous material.

In Mexico, we recently acquired a complete process plant on very advantageous terms that will help significantly reduced projected capital requirements for our Fenix project. This acquisition has made Fenix more attractive to build and could provide a new long life mine for McEwen Mining.

The San José mine, where we have a 49% interest, put in a strong quarter and its exploration is continuing to extend its high-grade veins and discover new veins.

We completed an $82 million financing for McEwen Copper in a very tough equity market. Rio Tinto, the second largest mining company in the world, through its subsidiary Nuton, now owns 9.7% of McEwen Copper, as a result of its investment of $25M. Also, Nuton is testing the Los Azules copper mineralization to see if it can accelerate and increase copper recoveries. Another of Rio Tinto’s subsidiaries, Kennecott Exploration, signed an option to earn 60% interest in McEwen Copper’s other copper project, Elder Creek, by spending $18 million on exploration. Elder Creek is located in Nevada.

In July our shares outstanding underwent a 10 for 1 consolidation. This was an unfortunate but necessary action done to protect our listing on the NYSE, which is our principal exchange and where our trading volume is the highest.

Production guidance for 2023 is 150,000 to 170,000 gold equivalent ounces (GEOs).

Later in this release I will explain why I believe MUX is an attractive investment” said Rob McEwen, Chairman and Chief Owner.

A webcast will be held on Monday, Nov 7th at 11:00 am EST. Management will discuss our Q3 financial results and project developments and follow with a question-and-answer session. Questions can be asked directly by participants over the phone during the webcast.

Selected Operational & Financial Information

Cash and cash equivalents at September 30th, 2022, totaled $54.9 million.

Q3 Production was 26,200 gold ounces and 852,200 silver ounces, or 35,700 gold equivalent ounces(1) (GEOs)(see Table 1), compared to 42,900 GEOs during Q3 2021.

YTD Production was 74,650 gold ounces and 1,894,100 silver ounces or 97,000 GEOs compared to 114,200 GEOs during 9 months to Sept. 30, 2021.

Revised guidance for 2022 production is 134,600-141,800 GEOs, reflecting a decrease of approximately 6,500 GEOs at Fox and 14,000 GEOs at Gold Bar due to carbonaceous material encountered throughout 2022, which should be alleviated with Gold Bar South beginning production, and an adjustment due to the gold:silver price ratio.

Average cash costs(2) per GEO sold from our 100%-owned mines (Fox & Gold Bar) in Q3 was $1,219, in-line with our guidance. Average all-in sustaining costs ("AISC")(2) per GEO sold from our 100%-owned mines was $1,659, slightly above our guidance midpoint of $1,475 per GEO.

Our 100%-owned mines generated a cash gross profit(2) of $5.8 million in Q3 and a gross profit of $1.5 million. Cash gross profit is calculated by adding back depletion and depreciation to gross profit.

Our consolidated net loss in Q3 was $10.5 million, or $0.21 per share, which relates primarily to $7.8 million spent on the Los Azules project, and $5 million on exploration and advanced projects at our mines. It is important to understand that MUX will continue reporting losses for some time because it is required to consolidate 100% of the expenses incurred by McEwen Copper for the development of Los Azules in its financial statements despite owning 68%.

Our exploration programs are focused on defining near-term mine resources that could extend our mine lives and contribute to future profitability. An update on our exploration activities will be released in the coming weeks.

Operations Update

Fox Complex, Canada (100% interest)

Fox achieved the lowest quarterly cash cost since mid-2018 of $774 per GEO sold. We believe there is good potential to further reduce costs and increase production at Fox Complex by increasing mill throughput. We plan to start crushing at the Froome mine site prior to transportation to the mill, which should relieve stress on the primarily crushing circuit.

In Q3, we incurred $2.7 million for exploration at Stock and at the Black Fox properties.

Gold Bar Mine, USA (100% interest)

Gold production continued to be low due to the presence of carbonaceous material that is being treated as waste and lower mining rates resulting from a contractor staffing shortage.

Development of the Gold Bar South deposit is underway. First ore is expected later in Q4. GBS has superior attributes compared to the current mining areas, because of its much lower waste stripping ratio, oxide mineralization with no carbonaceous material, and a higher average gold grade partially offset by lower heap leach recovery. Most of Gold Bar’s production in 2023 will be from GBS.

In order to increase our mining rate, a new mining contractor has been engaged and mobilization of equipment has started with a staged ramp up expected to be fully implemented in January 2023.

In Q3, we spent $1.1 million for exploration activities.

McEwen Copper (68% interest)

McEwen Copper is a key component of MUX’s value proposition. The Los Azules project is one of the world's largest undeveloped open-pit copper porphyry deposits. During the quarter, study work continued in parallel with preparation for the new drilling season which started in mid-October.

The closing of the $81.85 million financing was a critical step to fund activities necessary to complete an updated PEA (Preliminary Economic Assessment) for the Los Azules project. These activities included additional drilling, completing a new resource model, life of mine plan, baseline monitoring for environmental permitting, community development and relations, other technical work and general corporate purposes. McEwen Copper spent $7.6 million in Q3 to advance the Los Azules project. Publication of an updated PEA on the Los Azules copper project is planned for Q1 2023 and in Q2 an IPO is planned along with MUX completing a secondary financing reducing its interest to increase its treasury.   In the 2017 PEA, Los Azules is designed as an open pit copper mine with a 36-year life. However, it is possible that Los Azules could become ultimately an even larger mine, with a longer life, since numerous drill holes have shown strong copper mineralization extending below the pit bottom. It is not uncommon for porphyry copper deposits such as Los Azules, to extend well below 1,000 meters (3,280 feet) depth. During this season’s drill program, two deep high-grade targets will be drilled.

What might MUX be Worth?

“Value, like beauty, is frequently in the eye of the beholder. I am often asked what I think MUX is worth and I want to share my answer with you.

I have arrived at a high/low range of value for MUX by adding up the some of its parts. Here are the parts: MUX has a 68% interest in McEwen Copper, it owns 100% of three gold mines: Fox Complex, Gold Bar and El Gallo/Fenix, a 49% interest in the San José gold/silver mine, a portfolio of five royalties (NSRs) and a collection of exploration properties.

The operating challenges we faced in recent years have severely damaged our credibility with our shareholders and the market. As a result, few investors have taken a close look recently at our assets. If they did, I believe some would see the potential value that I see today. Yes, our cash is tight, our costs/oz are high and our mine lives are currently short, but that has been changing for the better. So let me show you my math and how I had arrived at a possible potential value for MUX of $8 to $30/share.

In this valuation estimate I have compared Los Azules to two copper projects, Josemaria and Filo, that are in the same province in Argentina as Los Azules. Compared to Los Azules these projects are located at substantially higher elevations, are at a greater distance from critical infrastructure (highways and power grid), have a smaller published copper resource base and copper grade, and they have public market values. Josemaria was purchased for $485M in April and Filo Mining has a market capitalization of $1.6B. The low end of the range is based on 50% of Josemaria’s purchase price and high end on Filo’s market capitalization.

For the valuation estimate of MUX’s gold and silver mining interests, we compared the average Enterprise Value (EV) per GEO production of five smaller producers. The low end of range is based on 50% of their multiple and the high end at par with their multiple. Please refer to the footnotes.

Table 2 Potential Share Value of MUX

MUX Assets	Value Range Per MUX Share(1)
	Low		High
Los Azules(2)	3.24(3)		21.36(4)
Elder Creek(2)	0.40(5)		0.40(5)
Royalty Portfolio	0.69(6)		0.69(6)
Gold & Silver Assets	3.75(8)		7.50(7)
Total	$8.08		$29.95

Table 2 Notes:

1. McEwen Mining has 51 million fully diluted shares
2. McEwen Mining owns 68.1% of McEwen Copper which owns 100% of Los Azules and Elder Creek
3. Josemaria purchase price was $485 million. ($485M x 50% x 68.1%) / 51M
4. Filo Mining market capitalization $1.6 billion. ($1.6B x 68.1%) / 51M
5. Elder Creek value is based on earn-in ($18M / 60%) x 68.1% / 51M
6. Royalties: 1.25% NSR on Los Azules and Elder Creek, plus three other royalties. Est. $35M / 51M
7. Average peer group (Jaguar Mining, Silvercorp, Fortitude, Gold Resource, Endeavour Silver) EV/GEO multiple 2.14x higher than MUX
8. Average peer group EV/GEO x 50%

As you can see, I believe there is considerable potential value in MUX, and that is a big reason why I have a personal financial commitment of $220M in MUX and McEwen Copper. Another way to look at MUX is that its current share price of $3.66 reflects the low end of potential value of the company’s ownership in McEwen Copper and you get all the other assets for free,” said Rob McEwen, Chairman and Chief Owner.

CAUTIONARY NOTE REGARDING NON-GAAP MEASURES

In this release, we have provided information prepared or calculated according to United States Generally Accepted Accounting Principles ("U.S. GAAP"), as well as provided some non-U.S. GAAP ("non-GAAP") performance measures. Because the non-GAAP performance measures do not have any standardized meaning prescribed by U.S. GAAP, they may not be comparable to similar measures presented by other companies.

Cash Costs and All-in Sustaining CostsCash costs consist of mining, processing, on-site general and administrative costs, community and permitting costs related to current operations, royalty costs, refining and treatment charges (for both doré and concentrate products), sales costs, export taxes and operational stripping costs, and exclude depreciation and amortization. All-in sustaining costs consist of cash costs (as described above), plus accretion of retirement obligations and amortization of the asset retirement costs related to operating sites, sustaining exploration and development costs, sustaining capital expenditures, and sustaining lease payments. Both cash costs and all-in sustaining costs are divided by the gold equivalent ounces sold to determine cash costs and all-in sustaining costs on a per ounce basis. We use and report these measures to provide additional information regarding operational efficiencies on an individual mine basis, and believe that these measures provide investors and analysts with useful information about our underlying costs of operations. A reconciliation to production costs applicable to sales, the nearest U.S. GAAP measure is provided in McEwen Mining's Form 10-Q for the period ended September 30th, 2022.

Cash Gross ProfitCash gross profit is a non-GAAP financial measure and does not have any standardized meaning. We use cash gross profit to evaluate our operating performance and ability to generate cash flow; we disclose cash gross profit as we believe this measure provides valuable assistance to investors and analysts in evaluating our ability to finance our ongoing business and capital activities. The most directly comparable measure prepared in accordance with GAAP is gross profit. Cash gross profit is calculated by adding depletion and depreciation to gross profit. A reconciliation to gross profit, the nearest U.S. GAAP measure is provided in McEwen Mining's Form 10-Q for the period ended September 30th, 2022.
