Horizon Copper Corp. (TSX-V: HCU) (“Horizon Copper”, “Horizon”, or the “Company”) is pleased to provide updates related to its portfolio of assets.

“With the volatility and economic uncertainty being experienced across all markets in recent months, we are pleased that Horizon is in a position where it is generating cash flows from its recently acquired Antamina NPI asset while the development stage projects in which we have an interest continue to make positive advancements,” said Erfan Kazemi, CEO & President of the Company. “In particular, the recent announcement by SSR Mining regarding infill drill results at Hod Maden provides further confirmation about the quality of the asset and the potential for Horizon to derive significant value from its interest as it moves into production in the coming years.”

SSR Mining Inc. (“SSR Mining”), the project developer and operator at Hod Maden, has commenced an infill drilling campaign to de-risk the ramp-up of initial mining at the project, expected in 2027. The three holes with assays returned to date include a highlight intercept of 90 metres at 16.5 grams per tonne (“g/t”) gold and 1.56% copper, reiterating the remarkable nature of the Hod Maden orebody.

Highlights of the infill drill results include:

  • HTD-238: 26 metres at 18.5 g/t gold and 3.24% copper from 256 metres, including:
    • 16 metres at 27.0 g/t gold and 3.74% copper from 259 metres;
  • HTD-239: 90 metres at 16.5 g/t gold and 1.56% copper from 162 metres, including:

    • 33 metres at 30.8 g/t gold and 2.86% copper from 197 metres;

Drilling intercepts reflect core length intersections; all results are uncut and reported at 1 g/t gold cut-off.

First Cash Flows from Antamina NPI

On August 15, 2023, the Company received its first payment in connection with the 1.66% net profits interest on the Antamina copper mine (the “Antamina NPI”) which was acquired from Sandstorm Gold Ltd. (“Sandstorm”) on June 15, 2023. Sandstorm retained a residual royalty (the “Residual Royalty”) on Antamina with payments equal to one-third (1/3) of the total Antamina NPI, after deducting the settlement of the Antamina silver stream for the period. All amounts reported by the Company are net of the Residual Royalty.

Net of the Residual Royalty, the Company received $5.1 million related to the operations at Antamina for the three months ended June 30, 2023. Of this amount, $1.2 million was used to settle obligations under the Antamina silver stream and $3.7 million was used to repay principal and interest on the Antamina promissory note with Sandstorm.

Going forward, the Company will receive quarterly payments under the Antamina NPI 45 days after each calendar quarter end. The proceeds from the Antamina NPI payments will be used to satisfy obligations under the silver stream and interest payments on the promissory note with Sandstorm. Any excess cash flow is expected to be used to repay the principal on the promissory note and reduce the Company’s debt.

Oyu Tolgoi Underground Development Update

In July 2023, Rio Tinto plc (“Rio Tinto”), the operator of the Oyu Tolgoi project, announced the continued ramp-up of the high-grade Oyu Tolgoi underground mine. Rio Tinto is managing the construction of Lift 1 of the Hugo North underground mine, including the Hugo North Extension, on both the Oyu Tolgoi mining license and the Entrée Resources Ltd./Oyu Tolgoi joint venture property (“Entrée/Oyu Tolgoi JV Property”). The Lift 1 mine plan incorporates the development of three panels, which are all required to be in production to achieve the full sustainable production rate of 95,000 tonnes per day from underground operations. The Hugo North Extension deposit on the Entrée/Oyu Tolgoi JV Property is located at the northern portion of Panel 1. 

Technical studies for Panels 1 and 2 mine design and schedule optimization were completed during the second quarter of 2023. According to Rio Tinto, the technical studies have resulted in substantially de-risked, resilient mine designs. The mine designs provide a pathway to ramp-up, the flexibility to pursue value-creating opportunities and react to future risks, as well as improved stability, constructability, and operability. The studies also provide a pathway to bring the panels into production faster and maximize the use of the ventilation system. Panel 1 production is anticipated to commence in 2027. The technical studies have been incorporated into an updated Oyu Tolgoi Feasibility Study to be submitted to and reviewed by applicable regulatory bodies in Mongolia. 

The Oyu Tolgoi project is located in Mongolia and is expected to become the fourth-largest copper mine in the world by 20301, operating in the first quartile of the copper equivalent cost curve.
