Phoenix, Arizona--(Newsfile Corp. - December 6, 2018) - Excelsior Mining Corp. (TSX: MIN) (FSE: 3XS) (OTCQX: EXMGF) ("Excelsior" or the "Company") is pleased to announce the closing of a US$9.4 million equity placement with affiliates of Greenstone Resources L.P. pursuant to the terms of a previously announced subscription agreement (see Excelsior news release dated November 21, 2018 - Greenstone Resources Confirms US$9.4 Million Equity Placement). Excelsior has issued to Greenstone an aggregate of 13,050,840 Excelsior common shares at an aggregate subscription price of US$9.443 million, or equal to approximately C$0.95 per share at current exchange rates (the "Greenstone Financing"). Greenstone now holds a total of 113,928,937 Common Shares, which represents approximately 48.56% of Excelsior's issued and outstanding Common Shares. The common shares issued to Greenstone in the Greenstone Financing are subject to a statutory four-month plus one-day hold period expiring on April 6, 2019.

Stock Option Exercise Program

The Company also confirms that it has implemented a stock option exercise program (the "Program") for the block of stock options that expire as of December 31, 2018. These stock options were originally issued from 2010 to 2012 and have been held by optionholders for 6-8 years. The intention of the Program was to minimize any impact on the Company's share price by avoiding the sale of a large block of shares all at once or over a short time period. The Program was also set-up to minimize dilution resulting from the exercise of stock options. The Program involved two steps. Firstly, optionholders completed a "net exercise" whereby optionholders receive a net amount of shares by reducing the amount they would otherwise be issued to cover the exercise price. The second step was the Company repurchased from each optionholder (at the market price) a sufficient number of shares to cover the taxes of the optionholders associated with the exercise. As a result of the Program, a total of 1,630,727 shares were repurchased by the Company and cancelled, and a final net amount of 3,407,479 shares were issued to optionholders. The Program was completed without any shares being sold in the market to cover exercise price or tax obligations.

Phoenix, Arizona--(Newsfile Corp. - December 4, 2018) - Excelsior Mining Corp. (TSX: MIN) (FSE: 3XS) (OTCQX: EXMGF) ("Excelsior" or the "Company") is pleased to announce that construction has started at the Gunnison Copper Project ("Gunnison"), in southeast Arizona; first copper production is anticipated in Q4 of 2019.

"Our ability to move quickly from the close of project financing to the initiation of construction at our Gunnison Copper Project is a demonstration of the operational capacity and experience of the Excelsior team," said Stephen Twyerould, President & CEO. "We look forward to updating all stakeholders as we move through the construction process. Our approach during this stage of development will remain, as always, focused on delivering technical excellence and long-term value for our shareholders."

Hydro Resources has commenced drilling the production wellfield and the accompanying compliance wells. Hydro Resources are experienced in-situ recovery ("ISR") wellfield drillers; this experience includes drilling for in-situ copper recovery projects. There are currently three drilling rigs on site with two additional drilling rigs arriving in January. A total of 63 wells, including 41 production wells and 22 compliance wells totalling approximately 82,000 feet will be completed. The significant number of compliance wells will ensure groundwater protection as per state and federal regulatory requirements. Drilling of the production wellfield is expected to be finished in Q2 of 2019. The initial wellfield area will be 400 feet by 400 feet with a spacing of approximately 70 feet between delivery and production wells.

Schmueser and Associates has been chosen as the general contractor. Construction activities will include:

  • Wellfield drilling and infrastructure - The wellfield has been designed to provide maximum operational flexibility including reversing wells and adjustable flowrates to maximize copper production.
  • Access road construction - An additional access road south of the I10 Highway is currently being installed. The Gunnison Copper Project is one of the most easily accessible mining projects in the world.
  • Johnson Camp Mine ("JCM") plant upgrades - Upgrades to the processing facilities include enhanced controls and instrumentation, new rectifiers, increased solution heating capacity as well as a number of other modifications that will ensure Gunnison produces Grade A, 99.999% pure copper cathode.
  • Pipeline distribution and infrastructure - A two-mile-long high-density polyethylene (HDPE) pipeline corridor will safely transport solution to the JCM processing facilities. Pipeline corridor liners, double-pipe containment and maintenance ponds will ensure best practice in terms of environmental management and safety.
  • Electrical distribution and infrastructure - Electrical distribution to the wellfield will include moving and utilizing the existing substation near the crushing facilities that are currently on care and maintenance; thereby providing substantial cost savings to Excelsior.
  • Process pond upgrades and completions - The existing ponds are being modified to accommodate the copper solutions from the wellfield. Additional pregnant leach solution (PLS) capacity is also being created at Gunnison to provide operational flexibility.
  • New acid storage facilities - These new facilities have been designed to enable the Company to take advantage of market acid pricing opportunities as they arise.

"Schmueser & Associates, LLC is pleased to have been selected as the General Contractor for the Stage I Gunnison Copper Project/Johnson Camp Mine," said Larry Schmueser II, President of Schmueser & Associates. "We look forward to working with Excelsior Mining Corp. on this low cost, environmentally friendly, copper production process. The goal of our Project Team puts a priority on safety with the understanding that achieving the budget and schedule are critical to the success of the project."

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.

Excelsior Mining Corp. (TSX: MIN) (FSE: 3XS) (OTCQX: EXMGF) ("Excelsior" or the “Company”) is pleased to announce that a Settlement Agreement (the “Agreement”) has been concluded that will result in the dismissal of the appeal (the “Appeal”) filed with respect to the Company’s Class III Underground Injection Control Area Permit (the “UIC Permit”) for the Gunnison Copper Project.

On June 22, the Environmental Protection Agency (the “EPA”) issued Excelsior the UIC Permit with an effective date of August 1, 2018. 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.”

This news release contains "forward-looking information" concerning anticipated developments and events that may occur in the future. Forward looking information contained in this news release includes, but is not limited to, statements with respect to: (i) the timeline for, and the completion of, the permitting process; (ii) economic benefits from the Gunnison Project; (iii) the commencement of commercial production from the Gunnison Project; and (iv) the ability to mine the Gunnison Project using in-situ recovery mining techniques.

In certain cases, forward-looking information can be identified by the use of words such as "plans", "expects" or "does not expect", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates" or "does not anticipate", or "believes", or variations of such words and phrases or state that certain actions, events or results "may", "could", "would", "might" or "will be taken", "occur" or "be achieved" suggesting future outcomes, or other expectations, beliefs, plans, objectives, assumptions, intentions or statements about future events or performance. Forward-looking information contained in this news release is based on certain factors and assumptions regarding, among other things, the estimation of mineral resources and mineral reserves, the realization of resource and reserve estimates, copper and other metal prices, the timing and amount of future development expenditures, the estimation of initial and sustaining capital requirements, the estimation of labour and operating costs, the availability of necessary financing and materials to continue to develop and construct the Gunnison Project in the short and long-term, the progress of development activities, the receipt of necessary regulatory approvals, the completion of the permitting process, the estimation of insurance coverage, and assumptions with respect to currency fluctuations, environmental risks, title disputes or claims, and other similar matters. While the Company considers these assumptions to be reasonable based on information currently available to it, they may prove to be incorrect.

Forward looking information involves known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking information. Such factors include risks inherent in the exploration and development of mineral deposits, including risks relating to changes in project parameters as plans continue to be redefined including the possibility that mining operations may not commence at the Gunnison Project, risks relating to variations in mineral resources and reserves, grade or recovery rates resulting from current exploration and development activities, risks relating to the ability to access infrastructure, risks relating to changes in copper and other commodity prices and the worldwide demand for and supply of copper and related products, risks related to increased competition in the market for copper and related products and in the mining industry generally, risks related to current global financial conditions, uncertainties inherent in the estimation of mineral resources, access and supply risks, reliance on key personnel, operational risks inherent in the conduct of mining activities, including the risk of accidents, labour disputes, increases in capital and operating costs and the risk of delays or increased costs that might be encountered during the development process, regulatory risks, including risks relating to the acquisition of the necessary licenses and permits, financing, capitalization and liquidity risks, including the risk that the financing necessary to fund the exploration and development activities at the Gunnison Project may not be available on satisfactory terms, or at all, risks related to disputes concerning property titles and interest, environmental risks and the additional risks identified in the “Risk Factors” section of the Company’s reports and filings with applicable Canadian securities regulators.

Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking information, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. Accordingly, readers should not place undue reliance on forward-looking information. The forward-looking information is made as of the date of this news release.
