Kelowna, British Columbia--(Newsfile Corp. - May 27, 2021) - Enduro Metals Corporation (TSXV: ENDR) (OTCQB: ENDMF) (FSE: SOG-FF) ("Enduro Metals" or the "Company") is pleased to report a new polymetallic vein system has been identified on the northern end of the Cuba Trend. The vein system, which is now known as Havana is the largest geochemical anomaly along the trend. The area is located approximately 1,500m directly west of the Chachi Central Zone (see news release dated February 18^th, 2021). Chachi and Havana (part of the Cuba Trend) are 2 of 4 major systems within the Company's 638 square kilometre Newmont Lake Project situated in the heart of BC's prolific Golden Triangle.

Figure 1: Cross-section of Line 7450M; the first and only induced polarization ("IP") geophysical work ever completed over the Havana Target. A subvertical chargeable conductor is prominent within the limestone host rock as is seen on surface. A multi-element soil anomaly is coincident with the geophysics, as well as rock sampling along strike where the vein is exposed on surface.

Highlights:

• A multi-element vein system has been identified as the possible source of the 1,800m long Havana geochemical anomaly.

• A sample of the quartz-barite vein on surface assayed 1,277 g/t silver, 4.51% copper, 1.11% zinc, and 0.21% lead. Another sample 60m along strike assayed 854 g/t silver, 5.34% copper, 4.34% zinc, and 1.53% lead.

• An induced polarization ("IP") geophysical survey line over the target identified an anomaly coincident with the surface geochemical anomaly.

• The company is currently investigating a possible link between Havana and Chachi - located 1,500m west of Havana.

Cole Evans, CEO of Enduro Metals commented, "The Havana area is the strongest silver anomaly across the Newmont Lake project by a considerable margin and we have now identified what could be the source for that anomaly. By applying a systematic, data-driven approach to exploration, we have developed a strong case for a large-scale, relatively easy access silver and copper system over a multi-kilometre area. With this new knowledge in hand, we are now investigating the possible links between Chachi and Havana, as well as viewing plans to increase the scope of the 2021 exploration drilling program by 2.5 - 3x larger compared to 2020. More details on this will be available shortly."

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 with the recent discovery of porphyry mineralization underneath the deposit along the McLymont Fault, copper-gold alkalic porphyry mineralization at Burgundy and 72 Zones, 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.
