Lode Gold Pivots Strategy to Focus on
Underground Opportunity & Presents Results
of the Evaluation of a Potential High-Grade
Underground Mine at Fremont, Mariposa, on
the Prolific Mother Lode Belt
Toronto, Ontario--(Newsfile Corp. - June 27, 2024) - Lode Gold Minerals Inc. (TSXV: LOD) (OTCQB:
SBMIF) ("Lode Gold" or the "Company" is pleased to present the results of the evaluation directed by
Carlos Saban, Lode Gold’s technical advisor, an exploration and mine geologist, regarding the potential
of a high-grade underground mine at Fremont, Mariposa. Mariposa, California is the original gold rush
county, where gold mining started back in 1848. Currently in California, there are over 700 permitted and
operating mines; 14 are gold mines. Mining operations was suspended in 1942 due to gold mining
prohibition during World War II. Previous owners of this project had solely focused on open pit
possibilities. Lode Gold, for the first time, since high grade (8 g/t Au) underground mining operation was
suspended in the 1940’s, has commissioned a study to evaluate the opportunity for an high grade
underground potential.
HIGHLIGHTS
Fremont is an orogenic gold deposit hosted in the ophiolitic suture of the 190 km Mother Lode
Belt. Mineralization is evidenced
on
a 4 km strike on the property
Mineralization is hosted both in the melange of the suture and in the slates of the Mariposa
Formation in the hanging wall
42,700 m of historical drilling comprises of diamond and reverse circulation holes
Current resource represents only 16% of the upper 500 m of the structure (Pine Tree - Josephine &
Queen Specimen; 2 of the 6 projects in the property)
The high-grade areas are controlled by transverse extensional faults
Average grade of historical channel sampling is 4.7 g/t
Au (vein average true width: 1.92 m)
Mineralization is hosted in a body that has veins with 5 g/t Au, 2 g/t Au of stockwork between veins,
and stockwork of 1 g/t of Au outside the veins
40% of mineralization is in veins, 30% in the stockwork between the veins, and 30% is outside the
veins
Only small portions of the veins were mined; stockworks outside the veins were not mined.
Historical production equals 16% of current M+I resource
Deepest drillhole hit mineralization 1,000 m below the surface and 1,300 m on the strike of the
structure
Upcoming drill plan - 4,500 m of step-out and infill drilling (upper 500 m of structure, short drill
holes) to expand current resources and to confirm high grade underground potential
Carlos has undertaken a detailed study of the historical information of the 2023 PEA to investigate the
potential of a high-grade underground mine at Fremont. The assays have been analyzed to study the
veins separately from the mineralized body as a whole.
Statistical Analysis
A statistical analysis of the grades from channel samples of the old underground workings reveals that
the width of the veins is constant with a mean of 1.92 m and at a 25
th
Percentile, 1.52 m. The grades
also show an even distribution with a mean of 4.7 g/t Au, a median of 2.9 g/t Au and at a 90
th
Percentile,
10.5 g/t Au (Table 1).

All assays from drillhole, surface and underground channels were processed with the Data Envelopment
Analysis Algorithm of Leap Frog® to study the grade distribution inside the body and the relationships of
gold mineralization in the different domains.

A review of the volumes of the statistical envelopes indicates that roughly 40% of gold mineralization is in
the veins (5 g/t Au), 30% of the gold is in the stockwork between the veins (2 g/t Au); and, 30% is in the
stockwork outside the veins (1 g/t Au).
Structural Controls
Using surface and underground maps and drillhole logs, a comprehensive lithological and structural
model was built to better understand the controls of gold mineralization at Fremont.
The mineralized bodies at Fremont are located along a 4-km long by 250-m wide shear zone of an
ophiolitic suture. In the central part of the project area, mineralization is controlled by the Pine Tree Vein
(hanging wall) and the Josphine Vein (footwall) with multiple smaller internal veins. The high-grade
mineralized areas inside of the bodies follow a pattern in which they are limited by transverse normal
faulting (Figure 2); this allows for the ranking and prioritization of key mineralized blocks for further drilling
to confirm Fremont's higher-grade potential.

Carlos used the 2023 PEA block model to study the entire mineralized body; he multiplied the grade of
each (5m x 5m x 5m) individual block by its length and then added the total of each row across the ore
body. This exercise produced a gram times meter (GM) "heat map" that provides a value for the intensity
of mineralization inside the block model. This "heat map" can be used as a vectoring tool to study
mineralized intensity and trends. Based on over 10,000 statistical samples, a mean of 58m with 96 GM
of Au was obtained for the entire mineralized block model (Table 2).

Figure 3 is a longitudinal section of the entire 4-km long property that shows the mineralization intensity
in gram-meters for the main deposits (French, Pine Tree-Josephine, Crown Point, and Queen
Specimen). The yellow arrows indicate the plunge direction of mineralization towards the North. The
figure also shows the traces of three deep drill holes undertaken by previous companies (drill hole length
of 720m, 780m and 1200m). Despite intersecting the main structure that hosts mineralization, these
deep step-out holes were directed outside of the mineralization plunges which explains the lower-than-
average grades that were obtained.

Conclusions
Fremont is an orogenic gold deposit situated within the ophiolitic suture of the Mother Lode Gold Belt in
California. Gold mineralization is found both in the melange of the suture and in the slates of the
Mariposa Formation in the hanging wall.
The investigation presented in this release reveals that the high-grade areas are primarily controlled by
transverse extensional faults. Furthermore, mineralization is found in veins, stockwork between veins,
and outside the veins. This distribution delineates the potential areas for mining and resource
estimation.
A statistical analysis of channel samples from old underground workings indicates consistent vein widths
and a wide distribution of gold grades, with a mean of 4.7 g/t Au. This statistical data aids in
understanding the variability and potential richness of the deposit.
The structural model built based on surface and underground mapping suggests that mineralized bodies
at Fremont are along a shear zone of the ophiolitic suture and that the high-grade mineralized areas are
limited by transverse normal faulting, which offers insights for further drilling and exploration efforts.
Using the PEA block model, the study generated a "heat map" indicating the intensity of mineralization
across the entire mineralized body. This provides a visual tool for understanding mineralized intensity
and trends, understanding the orientation of mineralized zones, and aiding in resource estimation and
future exploration strategies.
A drilling campaign of 4,500 m with lengths between 200 and 550m has been designed to expand
current resource in the Pine Tree - Josephine area and Chicken Gulch. It will focus on the shallow area
with the intention of connecting both areas, prove geological concepts and study the behavior of gold
mineralization in the different structural blocks of the north and central part of the structure.
