Aya Gold & Silver Extnds High-Grade Silver Mineralization at Depth at Zgounder

MONTREAL, Dec. 21, 2022 - Aya Gold & Silver Inc. (TSX: AYA) (OTCQX: AYASF) ("Aya" or the "Corporation") is pleased to announce additional drill exploration results, confirming the extension of high-grade silver mineralization at depth at the Zgounder Silver Mine in the Kingdom of Morocco.

Key Highlights (all intersections are in core lengths)

• At the central zone just below 2,000 meter ("m") level extending the high-grade zone discovered recently,
• hole TD28-22-2000-308 intercepted 3,956 grams per tonne ("g/t") silver ("Ag") over 21.60m including
• 5,792 g/t Ag over 14.40m
• hole TD28-22-2000-305 intercepted 5,691 g/t Ag over 9.60m including
• 8,840 g/t Ag over 6.00m
• hole TD28-22-2000-307 intercepted 1,972 g/t Ag over 15.60m including
• 2,538 g/t Ag over 12.00m
• Surface drilling including ZG-DCD-22-06 at the bottom contact with the granite intersected 1,220 g/t Ag over 6.50m and 5,132 g/t over 2.50m. ZG-22-64, intersected 2,074 g/t over 3.50m, confirming high-grade mineralization at, or near, the contact with the granite.
• From diamond definition drilling, DZG-SF-22-129 intercepted 708 g/t Ag over 11.00m, DZG-SF-122 intercepted 646 g/t over 11.00m and DZG-SF-135 intercepted 423 g/t over 13.50m upward from level 2,030m.

"Today's surface drilling results are part of our drill exploration program aimed at extending the high-grade mineralization at depth towards the granite contact at Zgounder," said Benoit La Salle, President & CEO. "We are very pleased with the overall continuity of the deposit, which continues to expand the known mineralization and deliver high-grade ounces."

Included in this release are results for 105 holes, which include 19 surface diamond drill hole ("DDH"), 13 underground DDH, 56 T28 and 17 YAK (T28 & YAK: percussion drilling using an air-compressed hammer) holes. For a full summary of today's results, refer to Appendix 1.

For core drilling, all individual samples represent approximately one metre in length of core, which is halved. Half of the core is kept on site for reference, and its counterpart is sent for preparation and assaying to African Laboratory for Mining and Environment ("Afrilab") in Marrakech, Morocco. All samples are analyzed for silver, copper, iron, lead, and zinc using Aqua regia and finished by atomic absorption spectroscopy ("AAS"). Samples grading above 200 g/t Ag are reanalyzed using fire assaying.

For definition drilling using T28 drilling equipment, all individual samples represent 1.2m in length. Samples are assayed at either the Zgounder Mine Laboratory ("ZMSM") or at Afrilab. At Afrilab, all samples are analyzed for silver, copper, iron, lead, and zinc using Aqua regia and finished by AAS. Samples grading above 200 g/t Ag are reanalyzed using fire assaying. At ZMSM, all samples are analyzed for silver only using Aqua regia and finished by AAS. Rigorous quality controls (QaQc) are applied at both locations.

Wherever possible, words such as "confirm", "extend", "continuity", "potential", "continue", "expand", "seems", and similar expressions or statements that certain actions, events or results "may", "could", "would", "might", "will", or are "likely" to be taken, occur or be achieved, have been used to identify such forward-looking information. Specific forward-looking statements in this press release include, but are not limited to, statements and information with respect to the exploration and development potential of Zgounder, the conversion of Inferred Mineral Resources into Measured and Indicated Mineral Resources and future opportunities for enhancing development at Zgounder. Although the forward-looking information contained in this press release reflect management's current beliefs based upon information currently available to management and based upon what management believes to be reasonable assumptions, Aya cannot be certain that actual results will be consistent with such forward-looking information. Such forward-looking statements are based upon assumptions, opinions and analysis made by management in light of its experience, current conditions, and its expectations of future developments that management believe to be reasonable and relevant but that may prove to be incorrect. These assumptions include, among other things, the ability to obtain any requisite governmental approvals, the presence of artisanal miners, obtaining regulatory permits for on site work, importing goods and machinery and employment permits, the accuracy of Mineral Reserve and Mineral Resource Estimates (including, but not limited to, ore tonnage and ore grade estimates), the price of silver, the price of gold, exchange rates, fuel and energy costs, future economic conditions, anticipated future estimates of free cash flow, and courses of action. Aya cautions you not to place undue reliance upon any such forward-looking statements.

The risks and uncertainties that may affect forward-looking statements include, among others: the inherent risks involved in exploration and development of mineral properties, including government approvals and permitting, changes in economic conditions, changes in the worldwide price of silver gold and other key inputs, changes in mine plans (including, but not limited to, throughput and recoveries being affected by metallurgical characteristics) and other factors, such as project execution delays, many of which are beyond the control of Aya, as well as other risks and uncertainties which are more fully described in Aya's 2021 Annual Information Form dated June 16, 2022, and in other filings of Aya with securities and regulatory authorities which are available on SEDAR at www.sedar.com.
