LAHONTAN ANNOUNCES 1,112,000 oz INDICATED and 544,000 oz INFERRED Au Eq

MAIDEN MINERAL RESOURE ESTIMATE at SANTA FE

Toronto, Ontario – January 17, 2023 – Lahontan Gold Corp. (TSX.V: LG, OTCQB: LGCXF) (the

“Company” or “Lahontan”) is pleased to announce the maiden Mineral Resource Estimate (“MRE”) for

its flagship Santa Fe Mine, a past-producing open pit, heap leach gold and silver mine located in Mineral

County, Nevada. The MRE for Santa Fe is based upon 1,275 drill holes totaling 125,435 metres, including

50 drill holes totaling 13,118 metres drilled by Lahontan since 2021.

Highlights of the MRE include:

• Project-wide pit constrained Indicated Mineral Resources of 1,112,000 contained gold equivalent

(“Au Eq”) ounces and Inferred Mineral Resources of 544,000 contained Au Eq ounces

(assumptions for Au Eq are described in the Notes to Tables 1 and 2).

• Project-wide average grade for the Indicated Mineral Resource is 1.14 g/t Au Eq; the average grade

of the Project-wide Inferred Mineral Resource is 1.00 g/t Au Eq.

• Indicated Oxide Resources total 21.6 Mt grading 1.03 g/t Au Eq for 712,000 Au Eq ounces and

Inferred Oxide Resources total 11.1 Mt grading 0.73 g/t Au Eq for 262,000 Au Eq ounces.

• The conceptual pit shells returned preliminary strip ratios (waste:ore) of 3.6:1 at the Santa Fe

deposit and 2.3:1 at the Slab-Calvada-York Complex. Within both conceptual pits, gold and silver

deposits crop out at the surface providing opportunities for rapid, low-cost mining operations.

• The MRE block model shows that gold and silver mineralization extends well beyond the

conceptual pit shells, generating high-quality targets for additional drilling and resource growth.

Kimberly Ann, Founder, CEO, and President of Lahontan Gold Corp commented: “Lahontan is thrilled

with the results of this MRE for the Santa Fe Mine, validating our business concept focusing on brownfield

exploration and development opportunities. The MRE demonstrates the presence of a large, readily

exploitable, oxide gold resource and importantly, higher-grade non-oxide gold resources. Shallow, good

grade oxide gold mineralization in the high-wall of the Santa Fe pit and outcropping oxide resources in

Slab-Calvada-York complex, give the Company a clear option for rapid mine development at a significant

production rate. We intend to take advantage of the technical and metallurgical data generated over six

years of historical mining and heap-leach processing to quickly evaluate the economic potential of the oxide

portion of the mineral resource. All deposits comprising the Santa Fe Mine remain open for resource

expansion and we look forward to continued drilling at Santa Fe as we grow and expand the size and scale

of the project”.

Table 1: Project-wide Resources, Santa Fe Mine, Mineral County, Nevada.

Notes to Tables 1 and 2:

1. Mineral Resources have an effective date of December 7, 2022. The Mineral Resource Estimate for the Santa Fe Mine was

prepared by Trevor Rabb, P.Geo., of Equity Exploration Consultants Ltd., an independent Qualified Person as defined by NI

43-101.

2. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. Inferred Resources are

considered too speculative geologically to have economic considerations applied to them that would enable them to be classified

as Mineral Reserves. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral

Resource and must not be converted to a Mineral Reserve. It is reasonably expected that most of the Inferred Mineral Resources

could be upgraded to Indicated Mineral Resources with continued exploration.

3. Resources are reported in accordance with NI43-101 Standards of Disclosure for Mineral Projects (BCSC, 2016) and the CIM

Definition Standards for Mineral Resources and Mineral Reserves (CIM, 2014).

4. Mineral Resources were estimated for gold, silver, and gold equivalent (Au Eq) using a combination of ordinary kriging and

inverse distance cubed within grade shell domains.

5. Mineral resources are reported using a cut-off grade of 0.25 g/t Au Eq for oxide resources and 0.60 g/t Au Eq for non-oxide

resources. Au Eq for the purpose of cut-off grade and reporting the Mineral Resources is based on the following assumptions

gold price of US$1,770/oz gold, silver price of US$22.00/oz silver, and oxide gold recoveries ranging from 60% to 77%, oxide

silver recoveries ranging from 40% to 55%, and non-oxide gold and silver recoveries of 71%, mining costs for ore and waste

of US$2.20/t, crushing cost of US$2.71/t, processing cost (oxide) US$6.80/t, processing cost (non-oxide) US$25/t.

6. An optimized open-pit shell was used to constrain the Mineral Resource and was generated using Lerchs-Grossman algorithm

utilizing the following parameters: gold price of US$1,770/oz gold, silver price of US$22/oz silver, gold selling costs of

US$56/oz gold, and silver selling costs of US$3/oz silver. Mining costs for ore and waste of US$2.20/t, crushing cost of

US$2.71/t, processing cost (oxide) US$6.80/t, processing cost (non-oxide) US$25/t, G&A cost US$3.99/t. Royalties for the Slab,

York and Calvada deposits are 1.25%, and maximum pit slope angles of 50 degrees.

7. Totals may not sum due to rounding.

About the Santa Fe Mine:

The Santa Fe Mine is in the Walker Lane mineral belt of western Nevada approximately 50 km from the

town of Hawthorne in Mineral County. Nearby operating gold and silver mines include Isabella Pearl

(Fortitude Gold) and Borealis (Waterton). The Santa Fe Mine consists of four past-producing open-pits,

including the Santa Fe, Slab, Calvada East, and York deposits, within a 19 km2 land package 100%

controlled by Lahontan. Gold and silver production occurred between 1988 and 1995 utilizing heap-leach

processing that produced a reported 345,000 oz of gold and 711,000 oz of silver (Nevada Bureau of Mines

and Geology, 1995). Mineralization occurs as disseminated gold and silver hosted by Triassic age

calcareous rocks. Strong stratigraphic and structural controls of mineralization is evident. Considerable

exploration potential remains at Santa Fe and the Company intends to continue its aggressive exploration

program during 2023.

Table 2: Project-wide Oxide Resources, Santa Fe Mine, Mineral County, Nevada

Oxide Resources:

Oxide resources at the Santa Fe Mine occur at both the Santa Fe deposit and the Slab-Calvada Complex

which includes the Slab, Calvada East, York, and Calvada Central deposits. The contained Au Eq oxide

ounces for the Slab-Calvada Complex accounts for approximately 19% of the total Indicated Au Eq oxide

ounces and 29% of the total Inferred Au Eq oxide ounces. Mineral Resources at the Slab-Calvada Complex

are exposed at surface. Oxide resources are open to the north and east of the Slab open pit, along the Calvada

Fault, and at the York open pit.

The Santa Fe deposit accounts for 81% of Indicated contained Au Eq oxide ounces, and 71% of Inferred

contained AuEq oxide ounces. Oxide Mineral Resources within the Santa Fe deposit are primarily located

in the high wall of the Santa Fe open pit. The average grade of the Santa Fe deposit Indicated oxide resource

is 1.10 g/t Au Eq, and Inferred oxide resource is 0.77 g/t Au Eq. Oxide resources at the Santa Fe deposit

are open to the northeast, south, and southeast.

Santa Fe Non-Oxide Resources:

Non-oxide resources at the Santa Fe Mine are principally located in the Santa Fe deposit below the oxide

resources within the resource pit shell. The average grade of the Santa Fe deposit Indicated non-oxide

resource is 1.41 g/t Au Eq and the Santa Fe deposit Inferred non-oxide mineral resource is 1.50 g/t Au Eq.

Gold is very fine-grained and associated with pyrite. Within the southeastern portion of the Santa Fe deposit,

higher-grade gold and silver resources may positively influence project economics. Higher grade gold and

silver mineralization extends to the southeast of the Santa Fe deposit, along strike and down-rake, providing

excellent exploration opportunities to grow the non-oxide resources at Santa Fe.

Estimation Approach:

Lithology and gold and silver bearing domains were modelled using Leapfrog Geo 2022. These domains

are mainly defined by logged jasperoid and limestone-breccia lithologies and continuity of gold grades

above 0.1 g/t gold. Ore type domains for oxide, transition and non-oxide were modelled based on ratio of

cyanide leachable gold assay values to fire assay gold values in addition to drillhole logs recording

abundance of pyrite and oxidation intensity. Transition material represents less than 5% of oxide tonnes

and is included in the oxide resource. Domains representing lithology, weathering and mineralization

models were assigned to a block model with a block size of 5 m x 5 m x 6 m. Average bulk densities

representative of the mineralization and lithology models were assigned to the block model and vary from

2.4 t/m3 to 2.6 t/m3.

Grade capping and outlier restrictions were applied to gold and silver values and interpolation parameters

respectively. Top cut values for gold and silver were evaluated for each domain independently prior to

compositing to 1.52 m lengths that honor domain boundaries. Estimation was completed using Micromine

Origin with Ordinary Kriging (OK) and Inverse Distance cubed (ID3) interpolants. Blocks were classified

in accordance with the 2014 CIM Definition Standards. The nominal drillhole spacing for Indicated Mineral

Resources is 50 m or less. The nominal drillhole spacing for Inferred Mineral Resources is 100 m or less.

Prospects for eventual economic extraction were evaluated by performing pit optimization using Lerchs-

Grossman algorithm with the following parameters: gold price of US$1,770/oz gold, silver price of

US$22/oz silver, gold selling costs of US$56/oz gold, and silver selling costs of US$3/oz silver. Mining

costs for ore and waste of US$2.20/t, crushing cost of US$2.71/t, processing cost (oxide) US$6.80/t,

processing cost (non-oxide) US$25/t, G&A cost US$3.99/t. Royalties for the Slab, York and Calvada

deposits are 1.25%. Maximum pit slope of 50 degrees. Processing recoveries range from 60% to 77% for

oxide, silver recoveries range from 40% to 55% for oxide and non-oxide gold and silver recoveries are

71%.
