CF TBD – Download

Horizon Copper Corp. (TSX-V: HCU) (“Horizon Copper”, “Horizon”, or the “Company”) is pleased to announce it has closed the second part of the previously announced reverse takeover transaction (“RTO Part B”) whereby the Company acquired a 1.66% net profits interest on the low-cost, high-grade Antamina copper mine (the “Antamina NPI”) from Sandstorm Gold Ltd. (“Sandstorm”). With the completion of RTO Part B and the approval of the TSX Venture Exchange (“TSX-V”), common shares of the Company are expected to resume trading on the TSX-V on June 21, 2023 under the symbol HCU.

“This is an exciting day for Horizon Copper,” said Erfan Kazemi, CEO & President of the Company. “We officially add another world-class copper asset to Horizon’s portfolio that will provide significant cash flows to Horizon immediately. It is extraordinary to have a portfolio like Horizon’s right out of the gate and I want to thank our shareholders and partners for their support in making this happen. We are excited to continue to grow Horizon in meaningful ways over the coming months and years as we build the next premiere copper company.”

Purchase of Antamina NPI and Closing of RTO Part B

As consideration for the Antamina NPI, Horizon provided to Sandstorm:

  1. US$20 million in cash (the “Cash Component”);
  2. A 1.66% life-of-mine silver stream referenced to the silver production from Antamina (the “Antamina Silver Stream”);
  3. A long-term secured convertible note with a principal amount of US$149.1 million; and,
  4. 2,329,849 common shares of the Company (the “Equity Component”).

In addition, Sandstorm also retained a residual royalty with payments equal to approximately one-third of the total Antamina NPI, after deducting the Antamina Silver Stream (the “Residual Royalty”).

The Cash Component was funded from the Company’s existing working capital and the proceeds from the private placement financing (the “Private Placement”) that was completed in April 2023 (see the Company’s press releases dated April 17th and April 20th).

With the completion of RTO Part B and the satisfaction of certain escrow release conditions, the proceeds from the Private Placement have been released from escrow and the subscription receipts from the Private Placement were converted into a total of 8,378,500 common shares of the Company and 4,189,250 nontransferable share purchase warrants (the “Warrants”). Each Warrant entitles the holder thereof to purchase one common share of the Company at an exercise price of C$1.10 (or US$ equivalent) per share for a period of four (4) years.

The Company previously announced its intention to complete a US$15 million secured convertible debt financing (the “Convertible Debt”) (see press release dated April 17, 2023). With SSR Mining Inc.’s (“SSR Mining”) recent acquisition of an operating interest in the Hod Maden project (in which the Company owns a 30% interest), SSR Mining provided updated development timelines that indicate a longer period for the remaining construction and development activities at Hod Maden than was previously expected. As a result, Horizon expects that it will have ample liquidity to fund its operations for at least the next 18 months, and no longer requires immediate proceeds from the Convertible Debt. Deferring or eliminating this financing option limits interest costs and curtails any dilution from the Convertible Debt.

Updated summaries of Available Funds and Principal Purpose of Funds for the next 18 months from those presented in the Company’s Management Information Circular dated July 26, 2022 describing the proposed RTO transactions to acquire certain assets from Sandstorm are as follows:

The stock options have an exercise price equal to the subscription price for the Private Placement (C$0.80) and expire five (5) years after the date of grant. Both the stock options and the RSRs vest annually in three equal tranches commencing with the first anniversary of the grant date.
