Enduro Intersects Gold in All Drill Holes; Sees

First Porphyry Mineralization in Drill Core at

McLymont - Introduces New Geological Model

Kelowna, British Columbia--(Newsfile Corp. - May 13, 2021) -

Enduro Metals Corporation

(TSXV:

ENDR) (

OTCQB:

ENDMF) (

FSE:

SOG)

("

Enduro Metals

" or the "

Company

") is pleased to report

assay results from 4,516m drilled in 17 diamond drill holes completed along the McLymont Fault during

the 2020 exploration program at Newmont Lake. The McLymont Fault is 1 of 4 major systems within the

Company's 638 square kilometre Newmont Lake Project situated in the heart of BC's prolific Golden

Triangle.

Highlights:

All 17 drill holes completed along a 4.5km-long continuum intersected gold mineralization of

varying styles and significance, including 2 types of skarns, intrusion related veins, and hypogene

porphyry mineralization.

NW20-13, the final drill hole of the 2020 exploration program intersected intrusion-hosted

hypogene porphyry mineralization along the McLymont Fault for the first time. This information is

critical to the Company's theory of an undiscovered porphyry camp at Newmont Lake (see Figures

5 & 6).

NW20-10 intersected a 25m wide vein swarm approximately 55m west of the 24m wide vein

swarm discovery in NW20-09 (see October 21

st

, 2020), now referred to as the Troy Veins.

Individual samples in the new vein intersections are as high as 20.30 g/t gold, 11.21 g/t silver, and

1.84% copper over 0.65m at 180.66m downhole.

Metallic screen analysis targeting selective gold mineralization saw up to 70% increases in

individual gold assays, including NW20-03 previously reported as 20.75 g/t Au over 1.00m is now

34.50 g/t Au over 1.00m at 55m downhole.

The Company is fully funded for a follow-up drill program in 2021 set to begin in June/July. More

information on the 2021 exploration program and further interpretations will be available shortly.

Zone, NE Extension, Troy, Lower Gold Zone, and Feeder have all been intersected in drilling. The

porphyry target, lower skarn target, and Goldfish have not been drill-tested.

Highlight drill results from 2020 exploration program include:

28.34m of 10.48 g/t Au, 2.31 g/t Ag, and 0.36% Cu @ 144.12m in Troy Veins.

Including 8.85m of 32.52 g/t Au, 6.54 g/t Ag, and 1.07% Cu @ 160m.

4.85m of 10.35 g/t Au, 15.93 g/t Ag, and 0.73% Cu @ 68m in NW Skarn.

103.30m of 0.90 g/t AuEq @ 15.54m in NW Skarn and Lower Gold Zone.

Including 1.00m of 35.12 g/t AuEq.

138.62m of 0.82 g/t AuEq @ 115.60m in NE Ext. Skarn and Lower Gold Zone.

Including 33.57m of 2.47 g/t AuEq @119.83m in NE Ext. Skarn.

22.23m of 2.20 g/t AuEq @ 18.83m in Ken Zone Skarn.

Including 10.84m of 4.06 g/t AuEq @ 21.64m.

156.12m of 1.89 g/t AuEq @ 6.86m from fully sampled R-07-09 in NW Skarn and Lower Gold

Zone

Including 86.29m of 3.27 g/t AuEq @ 6.86m.

144.00m of 3.30 g/t AuEq (uncut) @ 9.51m from fully sampled R-08-07 in NW Skarn and Lower

Gold Zone.

Including 55.70m of 7.72 g/t AuEq (uncut) @ 20m.

Including 0.49m of 759.40 g/t AuEq @ 25.25m.

Cole Evans, President/CEO of Enduro Metals commented,

"Despite initial setbacks, 2020 was a

transformative year for Enduro Metals, putting the Company in a great position heading into the 2021

exploration season. What is most important is we feel we have a strong understanding of the

geological story at Newmont Lake, allowing us to build off our success from 2020 and narrow our focus

to copper-gold porphyry systems. This is what we feel is the ultimate prize at Newmont Lake, and we

are now well-positioned scientifically to make that push.

Enduro's 2021 exploration program will start next month. More information will be released in the

coming weeks with details on 2021 plans and other geological interpretations/developments. We know

where we need to go, what we need to do, and we have the money to do it. I am very much looking

forward to getting in the field and making it happen."

Table 1:

Drilling results from all 17 drill holes completed in the McLymont Fault area listed in

numerical order.

Metal prices used in AuEq calculations are as follows: Gold $1650/oz, Silver $19.50/oz, Copper

$3.25/lb. The AuEq formula used for calculations is: AuEq g/t = (Au ppm * 100%) + (((Ag ppm * 0.63) *

100%) / 53.21) + (((Cu ppm * 0.007165029) * 100%) / 53.21) True widths are unknown as the

mineralized body remains open and requires further drilling. Recoveries are assumed to be 100% for

the purposes of equivalent calculations.
