On July 7, 2022, Yamana Gold issued a press release with news about its mining operations and development projects, including the Wasamac Underground Mining Project.

Advanced exploration: Applications for authorization to be filed soon

Last December, we announced the start of detailed engineering work ahead of submitting authorizations for bulk sampling at the Wasamac deposit, as per the recommendation in the updated feasibility study. Since then, our team has been busy planning this important step in the development of our project. Preliminary plans were presented to the Task Force last May and at the June neighbourhood meeting, where consultations were held regarding measures to be put in place to mitigate the impacts of this work. Applications for the various permits required will be submitted to the authorities shortly, detailing the construction of two access ramps to the deposit from the north of the 117 allowing for the recovery of a bulk sample and further exploration from underground exploration platforms. This new advanced exploration phase will allow us to recover a larger sample than we would with surface drilling to validate our predictions, including grade, recovery, backfill strategy and processing performance. It will also further our geotechnical knowledge and fine-tune the modelling for mine planning.

Project optimization continues to aim for a more efficient project

Over the last few months we have focused on updating the project’s strategic plan. The highlights are as follows:

• The acquisition of land adjacent to the site of the main surface infrastructure allows us to optimize its layout. The revised plan avoids environmentally sensitive areas and improves the layout of the processing plant and ore storage area, while continuing to minimize impacts on nearby residents.
• Additional geotechnical drilling has improved the design of the underground mine. The mining sequence also been optimized, allowing for a scenario of increased production in the first two years, to 200,000 ounces in 2027 and 250,000 ounces in 2028.
• The positive results of the exploration and infill drilling also allow us to formulate a new working hypothesis that suggests a potential increase of 7,000 tpd to 9,000 tpd in the third year of operation of the Wasamac mine. This would extend the gold production profile to 250,000 ounces per year until at least 2030, previously estimated at 169,000 ounces in the feasibility study. Further validation is under analysis to confirm this scenario, which would also require adjustments to the permit application process underway.

Further optimization work will be done in the coming months to fine-tune the treatment plan, the optimized configuration of the tailings filter plant and paste backfill plant and to further increase the levels of electrification, automation, and renewable energy used in our project.

Read the complete press release here.

We have a new and original way to communicate all of the information about the project’s many facets to the community.

The portal will keep visitors informed about our project while the social and environmental impacts are being assessed. You can also view different areas of the terrain where the Wasamac project is located.

In short, this portal features 3 digital tools:

1. The virtual tour. From the comfort of your own home, tour the community relations office in Évain. During this 360° virtual visit, you will find information panels and other interesting content about the Wasamac underground mining project.
2. An interactive map. Enables the user to call up themed maps, such as:

• The description of the Wasamac underground mining project.
• Information concerning the environmental and social impact assessment being done for the project, including certain components of the terrain.

Further layers of information will be added over the coming months, such as the findings of targeted analyses done for the environmental assessment.

1. A 3D model. A digital replica that shows the future infrastructures associated with the Wasamac underground mining project.

The portal will be enhanced over time as the environmental and social impact assessment progresses.

To access the portal, click here.

Should you experience any technical difficulties or need help using the portal, email us at wasamac@yamana.com or visit the community relations office at 14 rue d’Évain (Tuesdays through Thursdays, 9:00 AM to 5:00 PM). It will be our pleasure to assist you.

Enjoy your virtual experience!

P.S.:

Since this portal has just been launched, we would appreciate your feedback and any suggested improvements, both in terms of its content and its usability.

The Yamana Gold team is very pleased to announce that the company was recognized with a Distinction Award from the Quebec Mining Association (QMA) in the “Community Relations” category, at its annual convention held on June 9, 2022.

This award recognizes the work done around our drilling program and the innovative approach to community relations: adapting to the environment, rather than expecting the environment to adapt to our operations. Silence on fore! Is a good example of this approach.

Above all, we want to mention the valuable contributions and ongoing support of our partners, the neighbouring community, our Task Force and, of course, our service providers as we develop the project. With your involvement, feedback, ideas and questions, you’ve helped us push our limits and adapt our practices to achieve the objective of harmonious coexistence.

We will continue to focus on matching and defining industry best practices in community relations.

Invitation to the Fourth Neighbourhood Meeting

The 4th neighbourhood meeting regarding Yamana Gold’s Wasamac underground mining project will be held on June 14, 2022, at the Évain community centre at 100 rue Leblanc.

We will be setting up kiosks so that attendees can make the rounds and meet with different key people on the Yamana Gold team, as well as resource persons who can answer any questions you might have.

Join us to discuss such topics as:

• The mining project, for which the environmental impact assessment and exploration program are in progress;
• The advanced exploration program, for which applications for bulk sampling authorizations will soon be submitted and for which preparatory work will begin in the fall;

Come chat also with the Task Force members and share your views or suggest ideas for neighbourhood projects Yamana is interested in supporting.

Three time slots have been scheduled for persons who plan to attend:

• 4:00 PM
• 5:30 PM
• 7:00 PM

Contact us to reserve and confirm your time slot either by email at wasamac@yamana.com or by telephone at 1 833 510-0330 (toll free).

Open public meeting

All are welcome! See you then!

Yamana Gold is proud of its nomination for Silence on fore! in the Community Relations category

This announcement is recognition for the work we have done and our different approach to community relations: adapting to the environment, rather than asking the environment to adapt to our operations.

Silence on fore! is an excellent example. Since the acquisition of the property in 2021, the Yamana Gold team has been attentive to the neighbourhood’s needs, taking preventive measures to avoid potential impacts and fostering a harmonious co-existence with residents.

We also, and above all, owe this nomination to community participation. Thanks to the input of local residents, we were able to completely review our drilling practices in inhabited areas and enact new standards for noise reduction in urban environments. This is a real revolution in the world of drilling, enabling us to limit perceptible noise by at least 50%. For all this, we thank you all!

The winners will be announced on June 9 at the annual convention of the Quebec Mining Association.
