Phoenix, Arizona--(Newsfile Corp. - October 31, 2018) - Excelsior Mining Corp. (TSX: MIN) (FSE: 3XS) (OTCQX: EXMGF) ("Excelsior" or the "Company") is pleased to announce that the Company has entered into an agreement for a US$75 million project financing package. This comprehensive funding plan will enable Excelsior to transition the fully-permitted Gunnison Copper Project in southeastern Arizona into America's next new copper producer.

Stephen Twyerould, the President & CEO, commented, "In today's challenging mining market, only quality projects are able to secure funding. This financing delivers superior long-term economics for shareholders and allows us to quickly move into construction this year. Excelsior's pathway to achieving producer status is now clear, and we look forward to bringing the USA's next new strategic metal producer online in 2019."

Shaun Usmar, CEO of Triple Flag Mining Finance Ltd., commented, "Triple Flag is excited to partner with Excelsior to finance the Gunnison Copper Project. Our flexible and innovative financing will allow the Gunnison Copper Project to quickly proceed to construction and production over the next year, delivering a new, low-cost source of American copper. We congratulate the Excelsior team for its impressive progress in advancing this project to fully funded status."

Financing Package Highlights

The US$75 million project financing package (collectively, the "Financing") will be provided by Triple Flag Mining Finance Bermuda Ltd. ("Triple Flag"), and consists of a US$65 million copper metal stream (the "Stream") and a concurrent US$10 million private placement of common shares of Excelsior (the "Equity Placement"). The closing of these funding commitments is subject to various conditions, including the approval of the Toronto Stock Exchange. The Financing is expected to close during November 2018 (the "Closing Date").

Benefits for Excelsior

  • The Financing provides Excelsior with a comprehensive project funding solution that would cover all capital expenditures and working capital requirements related to the start-up of the Gunnison Copper Project.
  • The Stream is not subject to interest payments and is unsecured, thereby allowing for future project debt financing to expand the project production capacity up to the targeted 125 million pounds per year.
  • The Stream provides an option for Triple Flag to provide an additional US$65 million in funding for the second stage expansion of the Gunnison Copper Project, while also preserving the right of Excelsior to buy-down 50% of the Stream.
  • The Equity Placement provides further alignment between Excelsior and Triple Flag, with Triple Flag acting as a true project partner.
  • This transaction allows Excelsior to complete the construction without incurring project debt financing or the issuance of a large number of shares in a poor equity market.

Details of the Financing

Upfront Deposit

Excelsior and its subsidiaries, Excelsior Mining Arizona, Inc. ("Excelsior Arizona") and Excelsior Mining JCM, Inc. ("JCM"), have entered into a metals purchase and sale agreement (the "Stream Agreement") with Triple Flag, whereby Triple Flag has committed to fund a deposit of US$65 million (the "Stage 1 Upfront Deposit") against the future sale and delivery by Excelsior Arizona of a percentage of the refined copper production from the Gunnison Copper Project. Excelsior will sell to Triple Flag this percentage of refined copper at a price equal to 25% of the copper spot price. The exact percentages of copper production to be sold to Triple Flag varies as per the total production capacity. These percentages are detailed in the table below.

  Stage 1
(25 M lbs/yr)
Stage 2
(75 M lbs/yr)
Stage 3
(125 M lbs/yr)
Stage 1 Upfront Deposit 16.5% 5.75% 3.5%

 

"At full production of 125 million pounds per annum, and using the same US$2.75 copper price from our Feasibility Study, the Stream would add just an additional 7 cents per pound to our industry-leading all-in-sustaining operating costs of US$1.23 per pound," added Stephen Twyerould. "With this Stream, the Gunnison Copper Project would still be one of the lowest cost pure copper producers in the United States, and one of the lowest capex per pound copper projects in the industry."

In consideration of the Stream, Excelsior shall also issue to Triple Flag 3.5 million five-year common share purchase warrants, whose five-year term shall begin on the Closing Date, entitling Triple Flag to purchase 3.5 million Excelsior common shares at a strike price of C$1.50 per share issued.

Triple Flag Expansion Option and Excelsior Buy-Down Right

Subsequent to notice from Excelsior that the Company will be expanding production capacity to an amount equal to or greater than 50 million pounds per annum, Triple Flag will have the option to increase its stream participation by paying an additional US$65 million (the "Expansion Upfront Deposit").

Excelsior also retains the option to reduce the amount of the Stream by 50% by making a buy-down payment to Triple Flag (the "Buy-Down Payment"). The amount of the Buy-Down Payment depends on whether Triple Flag has exercised its option to provide the Expansion Upfront Deposit. The Buy-Down Payment is calculated as an amount that provides Triple Flag with an internal rate of return of 15% on 50% of the Stage 1 Upfront Deposit and, if applicable, 15% on 50% of the Expansion Upfront Deposit (in each case after taking into account the value of Stream deliveries (net of the 25% purchase price payment for such deliveries) made to Triple Flag prior to its payment).

The table below shows the percentage of production to be acquired by Triple Flag based on scenarios that include Triple Flag's Expansion Option and Excelsior's Buy-Down Right.

  Stage 1
(25 M lbs/yr)
Stage 2
(75 M lbs/yr)
Stage 3
(125 M lbs/yr)
Stage 1 Upfront Deposit + Expansion Option 16.5% 11.0% 6.6%
Stage 1 Upfront Deposit + Expansion Option + Buy-Down Right 16.5% 5.5% 3.3%
Stage 1 Upfront Deposit + Buy-Down Right 16.5% 2.875% 1.75%

 

Equity Placement

In conjunction with the Stream, Excelsior will complete the Equity Placement to raise proceeds of US$10 million (net of applicable fees and expenses). The Equity Placement will consist of the issuance to Triple Flag of an aggregate of 13,818,977 Excelsior common shares at an aggregate subscription price of US $10 million, or equal to approximately Cdn$0.95 per share at current exchange rates. In addition, affiliates of Greenstone Resources L.P. retain a pre-emptive right over the issuance of common shares of the Company. The overall size of the Equity Placement may be increased up to US$20 million dependent upon Greenstone's decision to exercise its pre-emptive right and in what proportion.

Phoenix, Arizona--(Newsfile Corp. - October 16, 2018) - Excelsior Mining Corp. (TSX: MIN) (FSE: 3XS) (OTCQX: EXMGF) ("Excelsior" or the "Company") announces that the Class III Underground Injection Control Area Permit for the Gunnison Copper Project (the "UIC Permit") is now active and good for production of up to 125 million pounds of pure copper cathode per annum. All required state and federal operating permits have now been successfully obtained.

Stephen Twyerould, President & CEO, said, "I'm extremely proud of our team that have worked so diligently with regulatory agencies, community and stakeholders to deliver this significant milestone. It represents a tremendous value-creation step as we continue moving towards production in what will be one of the most environmentally friendly and cost-effective copper projects in North America."

The Chairman of Excelsior Mining, Mark Morabito, added, "With the appeal process officially exhausted, we now have a fully permitted project that is genuinely on the cusp of achieving low cost copper production through the most environmentally friendly process available within the industry today. I congratulate the entire Excelsior team on achieving this positive outcome, and I look forward to seeing Excelsior unlock the true value of this tremendous asset."

To recap Excelsior's permitting process, in September, 2017, the Arizona Department of Environmental Quality ("ADEQ") issued an Aquifer Protection Permit for Gunnison Copper Project; this completed the Arizona State permitting process. On June 22, 2018 the Environmental Protection Agency (the "EPA") issued Excelsior the UIC Permit with an effective date of August 1, 2018. An appeal (the "Appeal") of the UIC Permit was subsequently filed by a coalition of non-governmental organizations (the "Petitioners") (See Excelsior Mining news release dated August 6, 2018 — "Excelsior Provides Permitting Update"). All appeals are reviewed by the Environmental Appeals Board (the "EAB"). Excelsior announced on October 5, 2018 that a Settlement Agreement (the "Agreement") had been concluded that would result in the dismissal of the Appeal. As per the terms of the Agreement, Excelsior, the EPA, and the Petitioners submitted to the EAB a joint motion to dismiss the Appeal (see Excelsior news release dated October 5, 2018 — "Excelsior Mining Confirms Agreement to Dismiss UIC Permit Appeal"). The EAB has now accepted the joint motion dismissing the Appeal, and the EPA has lifted the stay, thereby resulting in the UIC Permit becoming effective. The permitting process is now completed with all key operating permits in place and effective.

Excelsior will be ready to commence construction upon the completion of its project financing plan. The Gunnison Copper Project remains on-track to be the next new copper producer in the United States, with initial production scheduled for 2019.

An appeal of the UIC permit was subsequently filed by a coalition of non-governmental organizations (the “Petitioners”) (See Excelsior Mining news release dated August 6, 2018 – “Excelsior Provides Permitting Update”). All appeals are reviewed by the Environmental Appeals Board (the “EAB”). As per the terms of the Agreement, Excelsior, the EPA, and the Petitioners have submitted to the EAB a joint stipulated motion to dismiss the Appeal. It is anticipated that the EAB will accept the joint motion to dismiss the Appeal which, subject to notice by the EAB, will prompt the EPA to lift the stay, thereby resulting in the UIC Permit becoming effective with permanence.

The Agreement provides for additional monitoring wells and certain other matters. The Agreement does not take the place of the extensive protective measures, monitoring and reporting requirements of the Federal EPA UIC Permit and the State ADEQ Aquifer Protection Permit. However, it does provide for additional items that are a benefit to local stakeholders.

With all key permits in place and effective, Excelsior will be in position to commence construction upon the completion of its project financing plan. Excelsior’s Gunnison Copper project remains poised to be the next new copper producer in the United States.

Excelsior Mining Corp. (TSX: MIN) (FSE: 3XS) (OTCQX: EXMGF) ("Excelsior" or the “Company”) confirms that with respect to the Class III Underground Injection Control (“UIC”) Area Permit for the Gunnison Copper Project, the 30-day appeal period has officially ended. A total of two appeals were filed with the Environmental Appeals Board; however, one of these appeals was subsequently withdrawn prior to the termination of the appeal period. The remaining appeal raises no new objections that were not previously addressed as part of the comprehensive permit review process that was undertaken by the United States Environmental Protection Agency (“EPA”). Excelsior’s view is that this lone appeal will not be successful, and the Company intends to use all available legal means to have this appeal dismissed as soon as possible.

Appeals are reviewed by the Environmental Appeals Board. In order to be successful, the petitioner must demonstrate either a finding of fact or conclusion of law that is clearly erroneous, or an exercise of discretion on an important policy consideration that the Environmental Appeals Board should, in its discretion, review. The petitioner also must identify where in the record the issue was raised, or explain why it was not previously raised, and explain why EPA’s response to the comment was clearly erroneous or otherwise warrants review. Given the thoroughness of the process over the past 30 months, this is a difficult hurdle to meet and prevail.

Excelsior Mining Corp. (TSX: MIN) (FSE: 3XS) (OTCQX: EXMGF) ("Excelsior" or the “Company”) announces that the United States Environmental Protection Agency (“EPA”) has issued an operating permit, the Class III Underground Injection Control (“UIC”) Area Permit, for the Gunnison Copper Project, located in Cochise County, southeastern Arizona.

Stephen Twyerould, President & CEO, said, “The completion of this key milestone brings us one step closer to initiating low-cost in-situ copper production at one of the most environmentally friendly and economically compelling mine sites in the United States. We look forward to continuing our work with all regulatory agencies and stakeholders as we head into the construction phase this summer.”

The EPA has issued Excelsior a UIC Permit with an effective date of August 1, 2018.  Once effective, the UIC Permit (along with the Aquifer Protection Permit), requires the Company to be in compliance with protective permit conditions prior to the initiation of production activities. The UIC Permit is good for production of up to 125 million pounds per annum; this is the final operating permit required to get into production. In 2017, the Arizona Department of Environmental Quality issued an Amended Aquifer Protection Permit for the Johnson Camp Mine, and an Aquifer Protection Permit for the Gunnison Copper Project. 

Mark Morabito, the Chairman added, “There has not been a new copper mine permitted within the state of Arizona in over a decade; I congratulate the Excelsior management team for achieving this important milestone that keeps Excelsior Mining on schedule to become the next new copper producer in the United States.  In addition to generating significant economic benefits, the Gunnison Copper Project genuinely represents a more environmentally-friendly era of mining for Arizona.”

The second tranche resulted in the Company issuing 16,467,200 common shares at a price of C$1.00 per common share for gross proceeds of C$16,467,200 (approximately US$12.8 million). The second tranche was subscribed for by an affiliate of Greenstone Resources L.P. (“Greenstone”). The first and second tranches of the Private Placement resulted in the Company issuing 38,635,200 common shares for aggregate gross proceeds of approximately US$30 million.

Pursuant to the Private Placement, Greenstone purchased, by way of a treasury offering, common shares of Excelsior at a price of C$1.00 per common share for total gross proceeds of US$12.8 million.

Prior to the closing of the second tranche of the Private Placement, Greenstone owned 84,410,897 common shares of Excelsior, representing approximately 44.45% of the issued and outstanding common shares.  As a result of the closing of the Private Placement, Greenstone now holds a total of 100,878,097 common shares, which represents approximately 48.89% of Excelsior’s issued and outstanding common shares, representing an increase of approximately 4.4% from its ownership of common shares of Excelsior prior to completion of the second tranche of the Private Placement. The common shares issued to Greenstone in the Private Placement are subject to a statutory four-month plus one-day hold period expiring on May 20, 2018.

Stephen Twyerould, President & CEO, said, “This financing secures a significant amount of funding that allows us to continue advancing our Gunnison Copper Project towards production.  It is the fourth consecutive financing by Greenstone, which represents a significant endorsement of the Project and management team, by one of the most respected investment funds in the industry.”

The net proceeds of the Offering will be used for the development, construction and maintenance of the Company’s Gunnison Copper Project, including the acquisition of long lead items, and for working capital requirements.
