In This Article:

VANCOUVER, BC, March 8, 2024 /CNW/ - Entrée Resources Ltd. (TSX: ETG) (OTCQB: ERLFF) – the "Company" or "Entrée") has today filed its annual operational and financial results for the year ended December 31, 2023. All numbers are in U.S. dollars unless otherwise noted.

2023 HIGHLIGHTS

Oyu Tolgoi Underground Development Update

The Oyu Tolgoi project in Mongolia includes two separate land holdings: the Oyu Tolgoi mining licence, which is held by Oyu Tolgoi LLC ("OTLLC") and the Entrée/Oyu Tolgoi JV Property, which is a joint venture partnership between Entrée and OTLLC. Rio Tinto International Holdings Ltd. ("Rio Tinto") owns 66% of OTLLC and is the manager of operations at Oyu Tolgoi.

  • Ramp up of the Oyu Tolgoi Lift 1 underground mine, which incorporates the development of three panels (Panels 0, 1, and 2), continued during 2023. Oyu Tolgoi is set to become the fourth largest copper mine in the world by 2030, with the operation expected to deliver average mined copper production of ~500 ktpa between 2028 and 2036. 

  • On March 13, 2023, Rio Tinto announced the commencement of underground production from Oyu Tolgoi Lift 1 Panel 0 on the Oyu Tolgoi mining licence. As at December 31, 2023, 86 Lift 1 Panel 0 draw bells had been opened, including 67 draw bells during 2023.

  • Construction of conveyor to surface works continued to plan and was approaching 88% completion at the end of the year. Commissioning is expected in the second half 2024. Construction works for the concentrator conversion also remains on schedule. Commissioning is expected to be progressively completed between the fourth quarter 2024 through to the second quarter 2025. Construction of Primary Crusher 2 commenced in December 2023 and is expected to be completed by the end of 2025.

  • Shaft sinking continued during 2023. At the end of December, Shaft 3 reached 923 metres below ground level (82% sunk) and Shaft 4 reached 1,013 metres below ground level (86% sunk). Final depths required for Shafts 3 and 4 are 1,130 metres and 1,176 metres below ground level, respectively. OTLLC expects both shafts to be commissioned in the second half 2024.

  • Technical studies for Panels 1 and 2 mine design and schedule optimization were completed by OTLLC during the second quarter 2023. The Hugo North Extension ("HNE") deposit on the Entrée/Oyu Tolgoi JV Property is located at the northern portion of Panel 1. According to Rio Tinto:

    • The technical studies have resulted in substantially de-risked, resilient mine designs that provide a pathway to ramp-up, flexibility to pursue value creating opportunities and react to future risks, and 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.

    • Identified risks associated with the previous Panel 1 mine design have been resolved by increasing draw point and rim drive spacing, relocating the central material handling system and return raises outside of the active caving area, and optimally orienting the extraction drives and drill drives.

    • Panel 1 production on the Oyu Tolgoi mining licence is anticipated to commence in ~2027.

  • The technical studies have been incorporated into OTLLC's 2023 Oyu Tolgoi Feasibility Study ("OTFS23") which has been submitted to and is under review by applicable regulatory bodies in Mongolia. Entrée is currently reviewing OTFS23 but does not anticipate any material changes to underground development cost or schedule for the Entrée/Oyu Tolgoi JV Property.

  • Rio Tinto reported during its July 11, 2023 investor site visit that with the technical studies for Panels 1 and 2 completed, attention is shifting to the design of Lift 2. Drilling programs to support a Lift 2 Pre-Feasibility Study are in progress. An updated resource model for Hugo North (including Hugo North Extension) is expected to be completed in 2024 and will include mineralization from Lift 2.
