Adventus Mining Announces Award of Mining Contract for El Domo Copper-Gold Project and US$5M Equity Investment Commitment

TORONTO, Nov. 17, 2022 - Adventus Mining Corp. ("Adventus Mining") (TSXV: ADZN) (OTCQX: ADVZF) is pleased to announce that negotiations have concluded for the award of the open pit mining contract to a joint-venture between STRACON S.A., a well-established Peruvian mining contractor with operations throughout the Americas, and RIPCONCIV, a large and respected Ecuadorian infrastructure construction contractor ("STRACON-RIPCONCIV JV") for the development of the El Domo - Curipamba copper-gold project located in central Ecuador (the "Project"). The STRACON-RIPCONCIV JV partners have also confirmed an equity commitment to Adventus Mining for a total of US$5 million.

The mining contract has been structured in an alliance-partnership model to ensure focus on the best solutions for the Project and the optimal allocation of risks to the parties best equipped to manage and mitigate. The contract term is for a duration of 48-months which is projected to include the construction period as well as the first two years of operations. Adventus Mining and the STRACON-RIPCONCIV JV have the option to extend the contract further upon mutual agreement between the parties.

This contract is the largest anticipated to be awarded for the Project and includes scope generally consisting of open pit pre-strip and mining, and construction of the tailings facility, waste rock facilities, and associated mine infrastructure.

The previously announced Letter of Intent ("LOI") for this contract (see September 12, 2022 Adventus Mining news release) has allowed for preliminary training and planning work to commence in the El Domo Project communities since September 2022. STRACON-RIPCONCIV JV has already initiated aptitude assessments to select up to 70 people from the local communities surrounding the project for a mining equipment operator training program. The ongoing program has classroom, mining simulator, and hands-on equipment operation components and is in the process of ramping up. Adventus Mining and the STRACON-RIPCONCIV JV intend to hire the successful trainees to operate the equipment required to both construct the mine and execute mining activities during operations, resulting in skilled and high-paying employment opportunities for the local communities and broader multiplier benefits regionally in Ecuador.

STRACON S.A. and RIPCONCIV have both signed definitive binding agreements to make an investment in Adventus Mining under identical terms. An aggregate sum of US$5 million will be invested, comprised of US$2.5 million from each of the joint-venture partners.

The investment has been structured such that US$2.5M will be via a private placement calculated at the volume-weighted average price ("VWAP") on the TSX Venture Exchange for the ten consecutive trading days preceding the formal El Domo Project construction decision approval by Adventus Mining's Board of Directors, provided that the Project ESIA and all other permits required for construction have been received from the Government of Ecuador. The other US$2.5M will be issued in tranches once specific invoice thresholds have been achieved based on the 10-day VWAPs prior to issuance.

The technical information of this news release has been reviewed and verified as accurate by Mr. Dustin Small, P.Eng., Vice President Projects for Adventus Mining, a non-Independent Qualified Person, as defined by NI 43-101.
