Grading 0.70 g/t Au Eq Oxide at Santa Fe
TORONTO, ON / ACCESSWIRE / June 27, 2023 / Lahontan Gold Corp
(TSXV:LG)(OTCQB:LGCXF) (the "Company" or "Lahontan") is pleased to announce
results from the first four reverse-circulation rotary ("RC") drill holes from the Company's 2023
7,000 metre Phase Three drilling campaign exploring the Calvada pit area of the Company's 19
km2 Santa Fe Mine Project in Nevada's Walker Lane. Past mining, historic drilling, and the
Company's previously completed Phase One and Phase Two drilling programs had outlined
significant oxide domain gold and silver resources (Canadian NI 43-101 compliant) west of the
Calvada open pit that remain open along strike and down-dip*. The four drill holes reported
herein, totaling 883 metres, targeted these potential extensions to gold and silver resources.
Highlights include:
• 38.1 metres grading 0.87 g/t Au and 2.5 g/t Ag (0.89 gpt Au Eq) 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 gpt Au Eq). This drill hole, coupled with earlier Lahontan
drill results, shows that oxide gold and silver mineralization extends in a westerly
direction from the Calvada pit along the Calvada Fault, a key target area for resource
expansion. (Please see location map, cross section, and table below).
• 82.3 metres grading 0.68 g/t Au and 2.0 g/t (0.70 gpt Au Eq) of oxide metallurgical
domain mineralization in drill hole CAL23-001R, including 21.3 metres grading 0.93 gpt
Au and 1.9 gpt Ag (0.95 gpt Ag). This thick intercept should help expand the scale of the
conceptual pit shell used to constrain mineral resources in future resource estimates. This
intercept also contains a higher-grade interval which may be indicative of the margin of a
"feeder" structure. Oxide gold and silver mineralization remain open below CAL23-001R
generating yet another target for resource expansion at the Santa Fe Mine (Please see
cross section below).

Notes: Au Eq equals Au (g/t) + ((Ag g/t/75)*0.66). Ag grade for calculating Au Eq is adjusted to
consider historic metallurgical recovery as described in the Santa Fe Project Technical Report*.
True thickness of the intercepts is estimated to be 80-90% of the drilled interval. Numbers may
not total precisely due to rounding.

Kimberly Ann, Lahontan Founder, CEO, President, and Director commented: "These initial drill
results confirm the presence of extensive oxide domain gold and silver mineralization west of the
Calvada open pit. Modeling of this area during preparation of our Mineral Resource Estimate
("MRE") outlined multiple areas where new resources could be defined with in-fill and step-out
drilling. These drill results confirm this interpretation of the resource model and open new areas
for additional drilling. In addition, the high gold and silver grades seen in drill hole CAL23-004R
(4.6 metres grading 3.25 g/t Au Eq) suggests that we may have identified an important "feeder"
zone for gold mineralization in the Slab-Calvada complex."
Plan view of the Calvada pit area, Santa Fe Mine, Nevada. The outline of the Calvada pit is
shown in black with MRE conceptual pit shell shown in dashed red. Resource blocks are color-
coded for Au Eq grade in g/t. The four drill holes reported herein are shown with heavy green
drill hole traces, the line of the cross section (below) is also shown.
Cross section through Calvada pit area drill holes. These new zones of deeper oxide Au and Ag
mineralization have the potential to "pull-down" the conceptual pit shells used to constrain
resource estimation when the resource is updated following completion of the Phase Three
drilling campaign.
The plan view and cross section of the Calvada pit area (above) highlights the resource
expansion potential of the current drilling campaign. All four drill holes intercepted significant
oxide gold and silver mineralization, expanding the footprint of the Calvada resource to the west.
Mineralization remains open to the west, east and at depth and will be the subject of additional
drilling during 2023.
QA/QC Protocols:
Lahontan conducts an industry standard QA/QC program for its core and RC drilling programs.
The QA/QC program consisted of the insertion of coarse blanks and Certified Reference
Materials (CRM) into the sample stream at random intervals. The targeted rate of insertion was
one QA/QC sample for every 16 to 20 samples. Coarse blanks were inserted at a rate of one
coarse blank for every 65 samples or approximately 1.5% of the total samples. CRM's were
inserted at a rate of one CRM for every 20 samples or approximately 5% of the total samples.
The standards utilized include three gold CRM's and one blank CRM that were purchased from
Shea Clark Smith Laboratories (MEG) of Reno, Nevada. Expected gold values are 0.188 g/t,
1.107 g/t, 10.188 g/t, and -0.005 g/t, respectively. The coarse blank material comprised of
commercially available landscape gravel with an expected gold value of -0.005 g/t.
As part of the RC drilling QA/QC process, duplicate samples were collected of every 20th sample
interval at the drill rig to evaluate sampling methodology. Samples were collected from the reject
splitter on the drill rig cyclone splitter. Samples were collected at each 95- to 100-foot (28.96 -
30.48m) mark and labeled with a "D" suffix on the sample bag. No duplicates were submitted for
core.
All drill samples were sent to American Assay Laboratories (AAL) in Sparks, Nevada, USA for
analyses. Delivery to the lab was either by a Lahontan Gold employee or by an AAL driver.
Analyses for all RC and core samples consisted of Au analysis using 30-gram fire assay with ICP
finish, along with a 36-element geochemistry analysis performed on each sample utilizing two
acid digestion ICP-AES method. Tellurium analyses were performed on select drill holes
utilizing ICP-MS method. Cyanide leach analyses, using a tumble time of 2 hours and analyzed
with ICP-AES method, were performed on select drill holes for Au and Ag recovery. AAL
inserts their own blanks, standards and conducts duplicate analyses to ensure proper sample
preparation and equipment calibration. We have all results reported in grams per tonne (g/t).
