Exploration Update and Commencement of Trading on the CSE

Toronto, November 19, 2021 - Mongoose Mining Ltd. (CSE: MNG) (the "Company" or "Mongoose Mining"), is pleased to provide an update on recent exploration activities and announce that trading of the Company's common shares will commence at market open on Monday November 22^nd, 2021.

Project & Geological Update

Geological work on the Company's IOCG (Iron Oxide Copper Gold) project located near Londonderry, Nova Scotia (the "Project") is progressing well. The Company plans to aggressively explore this highly prospective region of Nova Scotia, Canada, and has retained Mercator Geological Services ("Mercator") to assist in the evaluation of numerous priority target areas previously identified.

• Mercator's compilation spanned over a four-month period incorporated over 200 reports and included digitising all the technical information into a data base. The data was carefully analyzed utilizing artificial intelligence logarithms developed for Mongoose using specific IOCG criteria.

• Twenty-eight (28) individual targets were generated of which nine (9) meet the highest category for discovery potential. It is the first time any company has utilized this highly advanced exploration technology in this area. All the data was digitized into 80 unique layers including geochemistry, geophysics, geology mapping and structural interpretations. Subsequently, an algorithm based on IOCG deposit models identified and ranked drill targets. Although significant exploration work has been completed, very little drilling has ever taken place within the Company's claims. Numerous areas throughout the Project were identified for drilling but due to lack of funding was never completed.

• The Company has initiated work programs on nine (9) high priority targets to identify locations for near-term drilling.

• In combination with a grant from the government of Nova Scotia, a 1,000 metre (6 hole) drill program on our exciting Cobalt Iron Gold target in the Bass River claim area was recently completed. A thick sequence of Magnetite and Pyrite breccia was intercepted in several holes. Cobalt mineralization has been associated with the Pyrite in previous historic assays from this area. Core samples have been shipped to Eastern Analytical laboratory in Newfoundland and the Company is awaiting results which are anticipated in January.

CSE Listing Update

President's Comments

"I'm very excited with the recent development of our priority targets, and look forward to drilling them shortly. Throughout the compilation process a primary focus for the geological team was to prioritize independently generated targets that coincided with historically significant results. One of which had historic gold assays as high as 5 grams per tonne and 1.77% copper. This area is very interesting, as no pervious drilling targeted this mineralization.

This coming year should be very exciting for the Company as these initiatives develop. We look forward to keeping the market updated on the Company's progress."
