Senior Rock Mechanics Engineer

Musselwhite Mine

Orla Mining is striving to be the emerging gold producer of choice with a geographically diversified asset
base, a prospective development and exploration portfolio, an experienced management team with a
successful track record, and a high-quality board and shareholder base.

Orla operates the Camino Rojo Oxide Gold Mine, a gold and silver open-pit heap leach mine, located in
Zacatecas State, Central Mexico. This low-cost operation is 100% owned by Orla, covers over 139,000
hectares, and includes a large sulphide mineral endowment located beneath the oxide resources. We are
also advancing permitting and development on our South Railroad Project, a feasibility-stage, open-pit
heap leach project located on the prolific Carlin trend in Nevada. This project is part our larger South Carlin
Complex which includes a prospective land package. We recently acquired the Musselwhite Mine located
in Northern Ontario on Lake Opapimiskan, a gold mine with more than 25 years of operating history. The
addition of Musselwhite has allowed Orla to more than double our gold production and provide a strategic
entry into a Tier 1 mining jurisdiction. The Musselwhite Mine is highly prospective with potential to expand
resources and mine life for years to come.

Orla is building a legacy of excellence, respect and sustainable value through responsible gold mining.
We are striving to create a net positive benefit for all and leaving a legacy beyond the life of our mines. We
do this through building and operating high quality mines supported and led by an experienced team. We
are custodians of the assets we run and the environments in which we operate, and we are committed to
fostering a culture of excellence, care, and respect.
