Fault
Kelowna, British Columbia--(Newsfile Corp. - April 4, 2023) -
Enduro Metals Corporation
(TSXV:
ENDR
) (OTCQB:
ENDMF
) (FSE:
SOG)
("
Enduro Metals
" or the "
Company
") reports the remaining
drill 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, Canada. An airborne magnetic survey has
also provided important supporting information at Burgundy Ridge ("Burgundy").
Drilling at the Burgundy porphyry target continues to encounter consistent copper and gold mineralization
from surface, with a second, high-grade mineralized zone identified at the limits of drilling.
These results
provide further evidence of an extensive alkalic porphyry system with geological similarities to Galore
Creek, the Teck/Newmont deposit 30km to the northwest of Enduro's project.
Drilling has also significantly increased the potential scale and prospectivity of the McLymont Gold
Project.
First pass drilling into the geochemical anomaly at McLymont West encountered mineralized
structures and enrichment in an area that has never been drilled before. The McLymont Gold Project,
related to the regional McLymont Fault which runs down the middle of our project, is emerging as a
stand-alone project.

Cole Evans, CEO of Enduro Metals, commented
,
"The 2022 exploration campaign was successful in achieving our two main objectives:
first to gather
the necessary data to produce a geological model that will allow us to better understand the size,
shape, and geometry of the mineralized system at Burgundy; and second to demonstrate that the
large geochemical anomaly at McLymont West was coincident with enrichment at depth.
"It is clear wherever we encounter mineralization in drilling at Burgundy; the grades, predictability, and
scale needed to make a project work in northwestern British Columbia, are there.
2022's deeper
drilling has identified the edges of a second mineralized zone with three successful intersections of
mineralization over a strike length of 210m.
"Despite our exploration still being relatively shallow for the porphyry environment, we will now focus
on completing the geological model to vector into the high-grade porphyry core, which is believed to
be the source of mineralization at Burgundy."
Burgundy Project
Enduro Metals drilled a total of 20 diamond drill holes at the Burgundy Cu-Au Alkalic porphyry target
during the 2022 exploration season.
Assay results are shown below in Table 1. The holes were designed
to test the scale and geometry of the mineralized footprint following the 2021 discovery hole (BR21-01 -
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 18th, 2021, NR
).
The program included 6 holes drilled at the Rock Islands and Telena Zone, nearly a kilometer northeast
of the discovery holes.
These drill holes encountered Cu-Au-Ag mineralization and are critical in our
program to vector into new zones of porphyry mineralization.

Full assay results of all holes drilled during the 2022 exploration season are set out in Table 1 below,
which also identifies results being reported for the first time in this news release.
The program has demonstrated that:
The Burgundy system is significant in size, with a current footprint of economic mineralization
measuring approximately 400m x 600m; mineralization is open, particularly to the southwest,
southeast, and at depth.
The controlling geology is complex, with numerous different styles of mineralization observed; the
key to unlocking its value will be in building a robust geological model to target future drilling.
The program has enabled Enduro Metals to gain a key understanding with respect to controls on the
porphyry mineralization at Burgundy. It has identified key structural and geological controls that are
contributing to the concentration of high-grade copper mineralization and will be important as the
Company seeks to vector into the larger porphyry system at depth.
The Company has previously discussed the importance of hole BR22-22 (see
January 16th, 2023, NR
)
which contained a high-grade interval of 1.24% CuEq over 24.20m at 445.80m, located approximately
170m underneath a high-grade interval recorded in the Burgundy discovery hole of 1.74% CuEq over
17.00m at 206.80m.
Of significance in the new assays, reported here for the first time, are holes BR22-17, 19, 20, and BR22-
21.
BR22-17, 19, and 21 were drilled from a single drill pad located on the top of the ridge,
approximately 200m northeast of BR21-01.
They have identified a series of unique, chalcopyrite-
dominant intrusions that appear to be sub-vertically orientated and occur relatively late in the system's
paragenesis, potentially as a later syn-mineral event (See Fig. 2). Intense alteration has nearly destroyed
the protolith; however, the alteration environment is accompanied by a disseminated chalcopyrite>pyrite
sulphide assemblage that has not been encountered before at Burgundy.

BR22-20 identified a discrete, high-grade zone towards the end of the hole.
This zone correlates with
similar zones encountered towards the end of holes BR22-22 and BR19-16, and points to a second
mineralized zone as shown in Figure 3 below.

The Company has also received the results of a drone magnetic survey completed at Burgundy (see Fig.
4)

Generally, increasing copper and gold grades appear to correlate with decreasing magnetic
susceptibility towards the west-southwest (see Anomaly A). Downhole magnetic susceptibility data also
supports these observations. Further drone coverage is necessary to understand the limits of Anomaly
A.
A large magnetically susceptible anomaly was also identified underlaying an approximate 200m x
500m outcropping of limestone at surface (Anomaly B). The source of Anomaly B is unknown currently.
Currently, the Company is focused on understanding the key structural and geological controls on
porphyry mineralization at Burgundy and building a comprehensive 3D geological model through
detailed re-logging of drill core at its core shack facility in Kelowna, BC.
This work will greatly support
drill planning as the Company looks to vector towards the center of the porphyry system at depth. An
important follow-up news release is expected by early May with the results of this exercise.
The exploration program for 2023 has yet to be finalised.
Key objectives for Burgundy include
identification of new porphyry centers, drilling step out holes to the southwest adjacent the newly
discovered copper-rich zone, and deeper holes to test the size and continuity of the system.
McLymont Gold Project
Enduro Metals drilled a total of 5 shallow diamond drill holes at McLymont West to test the large
geochemical anomaly identified during 2021.
Assay results are shown below in Table 2.
The holes were
drilled at the topographical high from two drill pads, located 120m apart, and more than 3 km from the
NW Zone in an area which has not been drilled in the past. The style and intensity of alteration in this new
target area are identical to that seen in the NW Zone.

First pass drilling in 2022 confirmed the presence of gold mineralization along strike of the McLymont
Fault, over an area with anomalous soil geochemistry discovered in 2021 (See
July 11th, 2022, NR
).
Results confirm the prospectivity of the large geochemical anomaly and point to a southern vector,
towards high-grade surface samples that have not yet been intersected by drilling.

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.

QAQC / Analytical Procedures
Core samples from the Newmont Lake Project were sent to MSALABS' 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 MSALABS'
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.
