LAHONTAN GOLD REVIEWS 2023 MILESTONES AND PLANS FOR 2024

Lahontan Gold Corp. has provided the following review of key milestones achieved by the company during 2023 and laid out Lahontan's mine development and exploration plans for 2024. Two thousand twenty-three was a transformative year for the company, beginning with the January release of the maiden mineral resource estimate* (MRE) for its 26.4-square-kilometre flagship Santa Fe mine project located in the Walker Lane of mining-friendly Mineral county, Nevada. Lahontan also completed two fully subscribed financings raising over $5.1-million, drilled almost 3,700 metres in the Slab-Calvada resource area, initiated baseline cultural and environmental studies covering almost half the Santa Fe mine project, acquired the 19.7 square km West Santa Fe gold-silver project, expanded Santa Fe via staking by 7.5 square km, and completed a comprehensive review/audit of all past metallurgical testing and production reports for Santa Fe. Details are below:

Santa Fe mine project MRE*: The MRE for Santa Fe, released in January, 2023, was based upon 1,275 drill holes totalling 125,435 metres, including 50 drill holes totalling 13,118 metres drilled by Lahontan since 2021 (the MRE does not include holes drilled later in 2023). Highlights of the MRE include:

  • Project-wide pit-constrained indicated mineral resources of 1,112,000 contained gold equivalent ounces and inferred mineral resources of 544,000 contained AuEq ounces (AuEq is based on the following formula: AuEq gram per tonne equivalent to Au g/t plus (Ag g/t divided by 75) and adjusted for historic differences in Au and Ag recovery during mine operations as described in the MRE).
  • Project-wide average grade for the indicated mineral resource is 1.14 g/t AuEq; the average grade of the project-wide inferred mineral resource is one g/t AuEq.
  • Indicated oxide resources total 21.6 million tonnes grading 1.03 g/t Au Eq for 712,000 AuEq ounces and inferred oxide resources total 11.1 Mt grading 0.73 g/t AuEq for 262,000 AuEq ounces.

Corporate financings: The company closed two equity financings during 2023, the first closing in February and March, the second closing in September (please see company press releases dated Feb. 28, March 8 and Sept. 1, 2023). Combined, the financings raised over $5.1-million, leaving Lahontan well financed to aggressively pursue its exploration and mine development programs.

Excellent drilling results in the Slab-Calvada area at Santa Fe: Lahontan completed 3,687 metres of reverse circulation drilling in 18 holes in the Slab-Calvada resource area at the Santa Fe mine project. The drilling targeted extensions of known resources, defined by the company's National Instrument 43-101 compliant technical report and MRE*, beyond the conceptual pit shells used in the MRE. Drilling highlights include:

  • 38.1 metres grading 0.87 g/t Au and 2.5 g/t Ag (0.89 g/t AuEq) of oxide metallurgical domain mineralization in drill hole CAL23-004R, including 10.6 metres grading 2.02 g/t Au and 2.4 g/t Ag (2.04 g/t AuEq);
  • 82.3 metres grading 0.68 g/t Au and two g/t (0.70 g/t AuEq) of oxide metallurgical domain mineralization in drill hole CAL23-001R, including 21.3 metres grading 0.93 g/t Au and 1.9 g/t Ag (0.95 g/t AuEq).

*Please see the Santa Fe project technical report, authors: Trevor Rabb and Darcy Baker, PGeos. Effective date: Dec. 7, 2022, report date: March 2, 2023. The technical report is available on the company's website and SEDAR+.

The Slab-Calvada area is particularly important from a mine development perspective as gold and silver mineralization crops out at the surface, is completely oxidized and would therefore be a logical area to resume mining operations. Lahontan believes that this drill campaign was highly successful in expanding the footprint of oxide gold and silver mineralization; these data will be included in an updated technical report as described below (please see Lahontan press releases dated June 27, July 18 and Sept. 12, 2023, for more information).

Plan of operations: In March, 2023, Lahontan and its consultants began work preparing an exploration plan of operations (POO) for the Santa Fe mine project. The POO covers approximately 12.1 square km of the 19.1 square km project area. The first phase of work is the completion of environmental baseline studies to document biological, cultural and surface water resources. Completion of the environmental baseline studies allows the POO to be designed to avoid specific resource conflicts. Eventual approval of the POO by the federal Bureau of Land Management (BLM) will allow more surface disturbance on the property, giving Lahontan the ability to continue to explore and expand the current mineral resources as well as provide baseline data that can be used in future mine permitting. Work completed to date includes:

  • Project initiation meeting with the BLM;
  • Biological baseline survey work plan;
  • Two special status plant surveys;
  • First burrowing owl survey;
  • Two acoustic bat surveys;
  • Seeps and springs surveys;
  • Majority of cultural surveys completed.

Upcoming work:

  • Final cultural survey before reporting;
  • Cultural reporting and agency review;
  • Fall 2023 and spring 2024 biological surveys, including flowering plants and raptor surveys.

West Santa Fe acquisition: In July, 2023, Lahontan announced an agreement to acquire the advanced West Santa Fe gold-silver exploration project (also known as Mindora), located only 13 km southwest of the Santa Fe mine project. West Santa Fe hosts an oxidized gold-silver epithermal mineralized system in a geologic setting similar to Santa Fe. Previous exploration drilling at West Santa Fe totals over 13,000 metres in 171 drill holes; only five holes are deeper than 165 metres. Preliminary modelling of drill hole data by Lahontan geologists outlines a significant, shallow, oxidized gold and silver system.

The acquisition agreement requires Lahontan to make payments totalling $1.8-million (U.S.) over a seven-year period, back-end loaded, to exercise an option to acquire a 100-per-cent interest in West Santa Fe. The option payments can be made in a combination of cash and shares at Lahontan's discretion. In addition, the company will commit to exploration expenditures totalling $1.4-million (U.S.) over the same seven-year period, these expenditures should be sufficient to define an initial mineral resource estimate for West Santa Fe (please see Lahontan press releases dated May 15, July 20, Aug. 15 and Aug. 16, 2023, for more details).

Lahontan also acquired an additional 794 hectares of mineral rights at West Santa Fe by staking 95 unpatented lode mining claims; the project now covers a of total 19.7 square km (please see Lahontan press release dated May 31, 2023). The Lahontan geologic team concluded that there was potential for significant resource expansion outside the original West Santa Fe claim group. The new unpatented mining claims also cover areas that could be used for potential future mining infrastructure such as heap-leach facilities.

Expand Santa Fe mine project: Lahontan significantly expanded its landholdings at its flagship Santa Fe mine project by staking 98 unpatented lode mining claims covering over 7.5 square km in November, 2023. The newly staked claims cover possible extensions to the Slab gold and silver resources*, other exploration targets covered by young gravel, and a vast area of flat terrain that could be suitable for mine infrastructure such as heap leach pads and waste rock dumps. The Santa Fe mine now covers over 26.4 square km, adding to the 64.1 square km the company controls in Nevada's prolific Walker Lane.

Metallurgical data review: The data review was completed by Kappes, Cassiday and Associates (KCA) of Reno, Nev., a global leader in metallurgical and process consulting. KCA reviewed metallurgical test work on oxide gold and silver mineralization completed by previous operators of the Santa Fe mine as well as production data. When recovery estimates of the individual deposits are applied to the MRE shown in the Santa Fe mine technical report*, it results in weighted project-wide gold recoveries of 74.4 per cent for gold and 29 per cent for silver at a one-half-inch crush size from oxide mineralization (please see Lahontan press release dated Jan. 22, 2024, for more information).

KCA believes that there are sufficient data available to establish recovery ranges of oxide gold and silver mineralization for inclusion in a preliminary economic assessment (PEA). This is a result of previous operational data, and the amount of column leach testing available on the component that makes up the bulk of the resource (the Santa Fe pit resource).

Plans and catalysts for 2024: Kimberly Ann, founder, chief executive officer, president and director, provided the following summary of company objectives for 2024: "Certainly 2023 was an enormous year for the company, establishing the size and scale of oxide mineral resources at Santa Fe and clearly moving Lahontan from being a pure explorer to a future mine developer. As we have outlined, the two critical paths going forward in 2024 for the company will be completing a PEA for Santa Fe and submitting a plan of operations to the federal Bureau of Land Management. These two key steps set the stage for a potential Santa Fe production decision in 2024. We are currently evaluating proposals from multiple prominent consulting groups to prepare the Santa Fe PEA. We expect to select a group to lead the PEA process shortly.

"Simultaneously, we intend to design and permit a phase 1 drill program for West Santa Fe, evaluate further drilling at the Santa Fe mine project, and, of course, continue to seek out opportunities that allow the company to jump-start the growth curve."
