The new drilling results include two surface holes, EGD174 and EDG177, the latter of which is the upper portion of “daughter hole” EDG177A (previously reported on July 18, 2024). Both holes were drilled steeply towards the northwest and crossed through approximately 1,350 to 1,400 m of barren, sedimentary and volcanic tuff units before intersecting the top of porphyry deposit. Starting at 1,352 m, drill hole EGD174 entered a 448 m interval of significant copper and gold mineralization, averaging 1.62% CuEq that includes 258 m within the footprint of the potential Lift 2 block cave, followed by an additional 190 m below the base of the footprint. The hole was eventually terminated at a depth of 1,800 m in strong copper-gold mineralization, which remains open at depth, and which the Company believes provides continuity for deeper, potential future lifts.

Significant mineralized intervals from the eight holes recently made available by OTLLC are summarized in Tables 1 and 2 and are shown on Figure 1.

2023 DRILLING INFORMATION

Surface and underground drill holes from the 2023 program were designed to achieve multiple objectives: as in-fill holes within the mineralized footprint of Lift 2 to support the next mineral resource estimate update; for geotechnical purposes in the areas outside of the mineralized footprint; and for metallurgical purposes. Several of the holes, denoted with letter suffix A, B, or C were drilled as “daughter holes” (wedges) from a “parent hole” at varying distances along the hole.

Surface holes UGD174 and UGD177 targeted the northern half of Lift 2, and were designed as in-fill holes, but also for geotechnical/metallurgical purposes. Underground drill holes UGD807A, UGD807B and UGD808 were primarily geotechnical holes drilled towards the north-northeast and targeting the area east of the potential Lift 2 mineralized footprint, yet all returned long intervals of lower grade, but above the cut-off grade (0.41% CuEq) used in the last mineral resource estimate (refer to press release dated June 15, 2021, titled “Entrée Resources Reports Updated Feasibility Study for its Interest in the Entrée/Oyu Tolgoi Joint Venture Property”). Three additional underground holes (UGD805B, UGD813, UGD814) were drilled at moderate dips towards the northwest or northeast and after crossing onto the Entrée/Oyu Tolgoi JV Property intersected significant grades of copper and gold in the southwest corner of HNE within the potential Lift 2 footprint.

The holes drilled into the mineralized porphyry intersected predominantly phyllic and potassic altered quartz monzodiorite, cut by occasional intervals of unmineralized biotite-granodiorite dikes (generally less than 10 m in drilled width). Total sulphide content is variable but averages around 5% and comprised of a mix of chalcopyrite, bornite and pyrite hosted in quartz stockworks and disseminated form. Some of the highest-grade individual assays (grading around 5% to 10% CuEq) are often hosted within hydrothermal breccias, containing a majority of disseminated and coarse bornite and chalcopyrite.

Drill holes outside of the HNE mineralized footprint generally crossed an interbedded sequence of ignimbrite and augite basalt with varying amounts of advanced argillic and phyllic alteration. Mineralization is variable, but consists of about 3% sulphides, comprised of a mix of pyrite and chalcopyrite.

2024 HNE DRILLING UPDATE

During 2024, OTLLC has continued to drill at HNE with all holes targeting the potential Lift 2 mineralized footprint. As of October 31, 2024, OTLLC had advised approximately 5,287 metres of underground drilling in 23 diamond drill holes and 2,476 metres of surface drilling in four diamond drill holes had been completed.

No analytical data has been received for any of the 2024 HNE drill holes, but once the complete database is received from OTLLC and reviewed by the Company the results will be reported. It is the Company’s understanding that, similar to the 2022 and 2023 drilling programs, all of the 2024 drill holes will be drilled within the current mineralized footprint or within the hanging and/or footwall rocks, with the objective to update the HNE mineral resource estimate and to conduct geological and geotechnical characterization.

SAMPLE PREPARATION AND ANALYSIS, QAQC AND QUALIFIED PERSON

Drill core from the eight drill holes reported was geologically and geotechnically logged at site by OTLLC. The surface drill holes were collared with PQ diameter core (123 mm) and reduced to HQ (96 mm) core diameter at depth. Underground holes were collared using HQ diameter and occasionally reduced to NQ (76 mm) at depth. Core from HNE was saw-cut on site before being bagged and shipped to the laboratory. Sample lengths generally averaged 2.0 m. Core from HNE was shipped to ALS Laboratory (“ALS”) in Ulaanbaatar, Mongolia, for sample preparation. ALS is independent of OTLLC, Rio Tinto and Entrée. At ALS the samples were crushed to <2mm and pulverized to 75μm, then the pulps were shipped directly to ALS in Perth for analyses. Samples were analyzed for gold by ICP-MS. Samples above approximately 0.03 g/t gold were further analyzed for gold by a 30-gram fire assay with an ICP finish. Samples were also analyzed for copper, silver and molybdenum, along with eight additional elements by 4-acid digestion, ICP-MS/AES multi-element analysis. Copper samples greater than approximately 1.0% were further analyzed by ore grade ICP ES/MS method.

OTLLC follows a rigorous quality assurance/quality control (QAQC) program for the sampling programs that includes the regular insertion of standards, blanks and duplicates into the sample stream. The QP is not aware of any drilling, sampling, recovery, or other factors that could materially affect the accuracy or reliability of the data referred to in this disclosure.

The scientific and technical information that forms the basis for parts of this press release was reviewed and approved by Robert Cinits (P.Geo.), who is a Qualified Person (“QP”) as defined by National Instrument 43-101.
