Aya Gold & Silver Advances Underground Development at Zgounder Silver Mine - Filing of 43-101 Expansion Feasibility Study Technical Report

MONTREAL, April 5, 2022 /CNW/ - Aya Gold & Silver Inc. (TSX: AYA) ("Aya" or the "Corporation") is pleased to provide an update on underground development work at the Zgounder Silver Mine in the Kingdom of Morocco.

Highlights

• Selection and mobilization of TRAV SOUSS MASSA ("TSM") to conduct the lateral underground mine development
• First blast carried out at end of January 2022
• 314 meters ("m") of lateral development effected to date
• Selection of CMAC-Thyssen ("CMAC") to carry out the vertical underground mine development including Alimak raises
• Mobilization scheduled for June 2022

"We are quickly de-risking our expansion and advancing the underground mine buildout with the timely award of the lateral and vertical development tenders and the mobilization of the two established contractors." said Benoit La Salle, President & CEO. "We are particularly thrilled to be working with a local contractor, which speaks to the depth of the mining services industry in Morocco. We look forward to updating stakeholders as we advance."

Contractor Selection

Aya launched a tender in November 2021 for the development of the Zgounder underground mine over a two-year period.

Moroccan-based TSM was selected to carry out the lateral development (main levels and connecting ramps), and CMAC was selected for the vertical development (four Alimak raises for ventilation, ore pass and waste pass).

TSM

TSM is a merger of three companies: TRAGI, TRAV SOUSS MASSA and CMDT. TSM was selected on the basis of its competitive offer, local presence, and experience in mining development. Additionally, TSM has an excellent track record over its nine-year history in Morocco.

Under the scope of its contract, TSM is responsible for the following project work streams including:

• First phase of lateral development for construction of the underground infrastructures
• Includes 4,262m of level development of various sections (4m x 4.5m and 4.5m x 5m) as well as 720m of ramp connections between underground levels
• Completion of the work over an 18-month period.

CMAC-Thyssen

CMAC is a Canadian contractor and manufacturer that has a presence in 15 countries and has been active in Morocco for over 10 years. CMAC was selected for being one of the best contractors in Morocco with Alimak raise excavation experience and for its ability to train local employees. An Alimak raise is a mechanized raise method used to develop escapeways, ventilation raises, ore and waste passes, and slot raises in underground mines.

CMAC will receive its equipment at Zgounder in June 2022 and will begin development of the 4 Alimak raises for expected completion within twelve months of the start date. The Alimak program will include:

• A ventilation exhaust raise of 9m² section and 187m length
• A ventilation intake raise of 9m² section and 130m length
• An ore pass of 4 m² section and 165m length
• A waste pass of 4 m² section and 180m length

TSM Development Update

In January, TSM launched the development and construction of the main underground infrastructures with the first blast of the new mine portal located at the 2,000m level (see Figure 1).

As of March 31, 2022, TSM had completed a total of 314m of lateral development between the 2,000m level and 1,975m levels as well as the ramps connecting the 1,975m and 2,000m levels and the 1,950m and 1,975m levels (see Figure 2). The next step is to connect the new and existing infrastructure at the 2,000m level in addition to preparing the area where CMAC will install the Alimak and develop the ventilation raise.
