Enduro's Initial 2022 Drill Results at Burgundy Extend Mineralized Zone and Support Large Scale Potential
Enduro's Initial 2022 Drill Results at Burgundy
Extend Mineralized Zone and Support Large
Scale Potential
Kelowna, British Columbia--(Newsfile Corp. - November 18, 2022) -
Enduro Metals Corporation
(TSXV: ENDR) (OTCQB: ENDMF) (FSE: SOG) ("
Enduro Metals
" or the "
Company
") is pleased to
report the first Burgundy Ridge ("Burgundy") drill hole results from the 2022 drilling campaign on the
Company's 100% owned Newmont Lake Project, located in the heart of British Columbia's Golden
Triangle. These drill holes were designed to test down-dip of mineralization drilled in 2019 associated
with a coincident IP anomaly. These first results are a proof-of-concept that highlight the correlation
between the IP anomaly discovered and mineralization at depth, while supporting the continuity of
mineralization across the Burgundy system in drilling by 400m along strike, remaining open both to the
northeast and southwest.

zones have been confirmed to nearly 300m down-dip and remain open with increasing primary

The program consisted of 10,888 metres of drilling within 25 diamond drillholes. Of these, 20 drill holes
were competed at Burgundy, and 5 drill holes were completed along the McLymont Fault (see
September 21
st
, 2022 News Release). Further results from this drill program will be reported as they are
received from the laboratory.
Highlights:
Newly received assays include BR22-23 which intersected 66.80m of 0.50% CuEq starting from
243.60m, including 6.08m of 1.82% CuEq
at 253.69m downhole. This primary mineralization is up
to 150m below supergene enriched mineralization in BR19-02 of 91.26m of 0.61% CuEq at 37m
downhole, including 39.0m of 1.02% CuEq at 69m downhole.
BR22-023 is a proof-of-concept drill hole that proves the correlation between chargeability highs
and prospective mineralization over the Burgundy system.
These assay results expand on discovery hole BR21-01 that intersected 331m of 0.71% CuEq
from surface, including 18m of 3.00% CuEq at surface, and 146m of 1.00% CuEq at 138m
downhole (see October 18
th
, 2021 NR) approximately 400m to the southwest.

this mineralized trend particularly to the southwest.

Cole Evans, Chief Executive Officer of Enduro Metals commented

"The first results from our
2022 drilling campaign demonstrate the association between chargeability and mineralization at
Burgundy, confirms the predictable and continuous nature of mineralization over a minimum of 400m
strike length and at depth. The system also appears steeper than we initially expected. This is a very
positive development as it leaves lots of room for deposit expansion at depth where porphyries tend to
have their highest grades.
The evidence was key for further drilling conducted 300m to 500m southwest, which are among the
deepest drillholes ever tested at Burgundy Ridge at over 600m downhole (assays pending). From a
porphyry perspective, we are still very shallow in the system with mineralization remaining open along
strike to the northeast, southwest, and down-dip.
Supergene enrichment is a natural geochemical enrichment process that increases copper and gold
grades near-surface from the movement of meteoric fluids over geological time.
The enrichment
process is very important as it concentrates high-grade material near surface, making it easily
accessible early in a theoretical production scenario. This is a rare phenomenon in Canada because
multiple ice ages covered the country in ice over geological time. Other examples of enrichment up to
2.5km along trend at Burgundy's 72' Zone where STDH21-01 intersected 9.4m of 2.17% Cu, and 27
g/t Ag only 16m downhole, showing that this is not an isolated event at Burgundy.
Figure 3:
Example of secondary (supergene) chalcocite and bornite with primary relic chalcopyrite
mineralization still visible. Malachite is noted to infill voids or other oxidized surfaces. This sample
assayed 1.53% Cu, 0.45 g/t Au, 7.42 g/t Ag, and 0.25% Zn over 2.27m at 75.3m downhole.

Table 1:
Reported assay intervals for BR22-23,
BR22-05, BR22-06, and BR22-08. Metal prices used
in CuEq calculations are as follows: Gold $1670/oz, Silver $21.50/oz, Copper $4.10/lb, and Zinc
$1.38/lb. The CuEq formula used for calculations is: CuEq % = (Cu ppm + ((Au ppm * $53.85) /
$0.009038960) + ((Ag ppm * $0.69) / $0.009038960) + ((Zn ppm * $0.003042382) / $0.003042382)) /
10,000. True widths are unknown as the mineralized body remains open and requires further drill
testing. Recoveries are assumed to be 100% for the purposes of equivalent calculations.

Geological Discussion
Figure 4:
New interpretations from 2022 drilling have identified the first syn-mineral intrusions on the
northern margins of Burgundy Ridge. These intrusions are a potential source of the chargeable
features seen in the IP survey across Burgundy Ridge.

BR22-023 was considered successful as a proof-of-concept drill hole.
It was planned to intersect the IP
chargeability anomaly at depth to explore the significance of this anomaly in relation to metal abundance.
Mineralization is expressed in blebby to disseminated chalcopyrite, with chalcocite observed regularly
downhole.
Proving the relationship between chargeability highs and copper mineralization at Burgundy is
a significant advancement that will aid vectoring efforts for all future planning.
New geological/geophysical interpretations using preliminary 2022 drilling data have identified the
potential source of the chargeable features at Burgundy Ridge as subvertical, syn-mineral plagioclase-
phyric porphyritic intrusions with disseminated sulphides cpy>py. While this intrusive phase is syn-
mineral, it is thought to be late in the mineralizing lifecycle of the Burgundy system and not the source of
high copper, gold, silver, and zinc-bearing breccias seen throughout the system. Clasts of the pre-
mineral megacrystic porphyry are present in the plagioclase-phyric intrusions.
Winter Research & Processing Facility
The Company has begun preparations for a research and processing facility in conjunction with the
University of British Columbia Okanagan near the Company's head office in Kelowna British Columbia,
Canada. The 2,500 square foot facility will allow for detailed lithological, alteration, and hyperspectral
studies to be performed on all drill core from the 2022 drilling campaign throughout the winter. This has
been made possible for the first time in part due to the now road accessible in-field core processing
facilities the Company has adjacent to the Newmont Lake Project.
Enduro Metals would like to thank Seabridge Gold and Obsidian Camps and Logistical Services for
their hospitality and efforts in making these in-field facilities available to the Company.
QAQC / Analytical Procedures
Core samples from the Newmont Lake Project were sent to MSA LABS' preparation facility in Terrace,
B.C., where samples were prepared using method PRP-910. Samples were dried, crushed to 2mm,
split 250g and pulverized to 85% passing 75 microns. Prepped samples were sent to MSA LABS'
analytical facility in Langley, B.C, where 50g pulps were analyzed for gold using method FAS-221 (fire
assay-AAS finish). Gold assays greater than 100 g/t Au were automatically analyzed using FAS-425 (fire
assay with a gravimetric finish). Rock samples were analyzed for 48 elements using method IMS-230,
multi-element ICP-MS 4-acid digestion, ultra-trace level. Silver assay results greater than 100 g/t Ag and
copper, lead, and zinc greater than 10,000ppm were automatically analyzed by ore grade method ICF-6.
Enduro Metals Corp conducts its own QA/QC program where five standard reference material pulps, five
blank reference material samples, and two field duplicates are inserted for every 100 samples when
analyzing core samples.
