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.

  • 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."

Drill Results:

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.

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.

About Enduro Metals

Enduro Metals is an exploration company focused on it's flagship Newmont Lake Project; a total 638km² property located between Eskay Creek, Snip, and Galore Creek within the heart of northwestern British Columbia's Golden Triangle. Enduro entered into an option agreement to acquire 436km² from Romios Gold Resources who has carefully amalgamated the area since 2005 from numerous smaller operators. Remaining terms on the option agreement are a $1,000,000 CAD cash payment, and issuance of 4 million Common Shares to Romios Gold Resources. Romios will retain a 2% Net Smelter Returns Royalty (an "NSR") on the Newmont Lake Project, or on any after-acquired claims within a 5 km radius of the original boundary of the project, which may be reduced at any time to a 1% NSR on the payment of $2 million per 0.5% NSR. The remaining 202km² is owned 100% by Enduro and was acquired via staking or cash purchase. Building on prior results, the Company's geological team have outlined 4 deposit environments of interest across the Newmont Lake Project including high-grade epithermal/skarn gold along the McLymont Fault, copper-gold alkalic porphyry mineralization at Burgundy, high-grade epithermal/skarn silver/zinc at Cuba, and a large 9km x 4km geochemical anomaly hosting various gold, silver, copper, zinc, nickel, cobalt, and lead mineralization along the newly discovered Chachi Corridor.
