As COO, Tim will have overall responsibility for the development, ramp-up and operation of the Valentine Gold Project in central Newfoundland. Tim brings a strong track record in project development and construction, with both La Arena and Shahuindo being established as successful, large scale gold mines under his management. Importantly, he also brings direct, hands-on experience in open pit mining operations as both a geotechnical engineer and mining contractor, key skillsets for success at the Valentine Gold Project. As we move forward with our Environmental Assessment and Feasibility-level engineering studies at the Valentine Gold Project, we expect to announce additional appointments to our mine development team with a view to a potential construction decision by late 2021.”

A mineral resource that is classified as “inferred” or “indicated” has a great amount of uncertainty as to its existence and economic and legal feasibility. It cannot be assumed that any or part of an “indicated mineral resource” or “inferred mineral resource” will ever be upgraded to a higher category of mineral resource. Investors are cautioned not to assume that all or any part of mineral deposits in these categories will ever be converted into proven and probable mineral reserves.

By its nature, this information is subject to inherent risks and uncertainties that may be general or specific and which give rise to the possibility that expectations, forecasts, predictions, projections or conclusions will not prove to be accurate, that assumptions may not be correct and that objectives, strategic goals and priorities will not be achieved. Factors that could cause future results or events to differ materially from current expectations expressed or implied by the forward-looking statements include receipt of all necessary regulatory approvals, completion of all conditions to closing of the Offering, availability of financing to fund Marathon’s exploration and development activities, the ability of the current exploration program to identify and expand mineral resources, operational risks in exploration and development for gold, Marathon’s ability to realize the pre-feasibility study, delays or changes in plans with respect to exploration or development projects or capital expenditures, uncertainty as to calculation of mineral resources, changes in commodity and power prices, changes in interest and currency exchange rates, the ability to attract and retain qualified personnel, inaccurate geological and metallurgical assumptions (including with respect to the size, grade and recoverability of mineral resources), changes in development or mining plans due to changes in logistical, technical or other factors, title defects, government approvals and permits, cost escalation, changes in general economic conditions or conditions in the financial markets, environmental regulation, operating hazards and risks, delays, taxation rules, competition, public health crises such as the COVID-19 pandemic and other uninsurable risks, liquidity risk, share price volatility, dilution and future sales of common shares, aboriginal claims and consultation, cybersecurity threats, climate change, delays and other risks described in Marathon’s documents filed with Canadian securities regulatory authorities.
