The Cabot Project – A Promising Copper-Gold-Cobalt Prospective Asset in a Proven and Expanding Mining District

The Cabot Project is a copper-gold-cobalt exploration property with two distinct mineralized zones: a copper-cobalt rich system known as the “Cabot Copper Zone” and a separate quartz vein hosted gold system known as the “Marble Cove gold Prospect” that covers over 48 square kilometres (4,800 hectares). The Project is strategically located in a top-tier mining jurisdiction with road access, power infrastructure, and proximity to producing mines.

Cabot Copper Zone Highlights:

• Surface sampling has returned up to 6.9% Cu (out of 21 samples), with multiple kilometre-scale mineralized trend identified in the Main Cabot VMS Zone. 1  

• Copper occurs as chalcopyrite and bornite within altered volcanic and sedimentary units, indicating a strong hydrothermal system.  

• Geophysics and soil surveys have defined 5 drill-ready targets; 4-of which have not been tested by drilling or trenching  

• The Project is located in a developing VMS District with a history of historic mine development just 15km from Firefly Metals Ltd.’s (“ Firefly ”) (ASX:FFM) Ming Copper-Gold Mine, with a significant mineral project with an estimated M I Resource of 21.5Mt of 1.8% CuEq with an inferred resource or 28.4Mt of 2% CuEq. 2  

Marble Cove Gold Prospect Highlights:

• A separate area of the Project hosts gold mineralization, with historic sampling returning up to 70.38 g/t Au. 3  

• Gold is associated with narrow, structurally controlled veins.  

• Situated in a favorable geological setting, approximately 4 km west and along strike of the mineralized trends of Maritime Resources Corp.’s (“ Maritime Resources ”) (TSX: MAE) Point Rousse Gold Project. Point Rousse has produced over 200,000 oz of gold and hosts three major mineralized trends, each extending 3 to 8 km before terminating at the coast. Marble Cove lies directly west, across the bay from these known gold-bearing structures.  

Qualified Person

Garth Graves, P.Geo., is an independent Qualified Person as defined by NI 43‑101 and has reviewed and approved the scientific and technical information contained in this news release. Mr. Graves has not independently verified the data disclosed herein.

Information regarding adjacent properties in which the Company holds no interests, including mineralisation and exploration results (e.g., Firefly’s Ming Mine and Maritime Resources’ Point Rousse Project), is provided for geological context only. The Qualified Person has not verified the information on adjacent or geologically similar properties, and such information is not necessarily indicative of mineralisation on the Cabot Project.

The sampling results referenced for the Cabot Copper Zone and the Marble Cove Gold Prospect are historical in nature and comprise selective grab samples collected by Ken Lewis (2000) and Dan Jacob (2024), respectively, and assayed by Eastern Analytical, an accredited laboratory in Newfoundland and Labrador. These samples were not collected under the supervision of the Company or the Qualified Person. The Company considers these results to be relevant as an indication of mineralisation potential; however, a Qualified Person has not completed sufficient work to classify these results as current mineral resources or mineral reserves. Accordingly, Centenario is not treating these results as current mineral resources or mineral reserves. Further exploration, including drilling and systematic sampling supported by appropriate quality assurance and quality control procedures, is required to verify these results.
