Tinka Discovers High Grade Tin Mineralization at South Ayawilca

Trevali Mining Corporation ("Trevali" or the "Company") (TSX: TV) (BVL: TV) (OTCQX: TREVF) ( Frankfurt : 4TI) provides an update on circumstances at the Perkoa Mine in Burkina Faso following the serious flooding incident on April 16 where the Company and government authorities have been working on the search efforts 24 hours per day.

The Company's overarching priority has been, and continues to be, finding the eight miners still missing at the mine. We are working 24 hours a day to dewater the mine and reach our missing colleagues and continue to work hand in hand with the Burkina Faso government, authorities and emergency services at all levels.

Despite the comprehensive efforts of the search teams, including the continued addition of extra pumping equipment during the search and de-watering process, we have yet to find the missing miners. There is a refuge chamber at a depth of approximately 570 metres which is primarily designed to provide protection from industrial hazards that workers might encounter underground, such as smoke from fire, gas emissions, fall-of-ground, and ventilation failure. We cannot be certain whether all or some of the miners managed to reach the refuge as we have had no communication with the missing since April 16 .

The miners were last located at various locations below Level 520 and based on planned work patterns that day and our last contact with them, it is unlikely that they would have been together when the flooding occurred, or that all of them would have been able to make it to the refuge.

In order to safely regain access to the mine, we have to rebuild the five-kilometre-long underground access ramp and to date we have restored more than 3,800 metres using more than 25,000 tonnes of waste rock. During this work, the massive scale of the flood has become clearer. We currently estimate that more than 165 million litres of floodwater swept through the underground portion of the mine. These floodwaters caused extensive damage to ramps and access roads, as well as underground infrastructure. Approximately 38 million litres of water has been pumped out of the mine as of May 11 .

All of us at Trevali are hugely grateful for the continued assistance provided by Burkinabe authorities, including enabling the imports of equipment for the search effort, and expediting air carriers able to transport heavy machinery into the country, which has greatly accelerated the dewatering and search efforts. The Company has also benefitted from the relocation of the crisis management committee to the Sanguié region near the Perkoa mine site and from the support provided by government officials in daily planning meetings. Trevali will continue to welcome support from those able to assist in the search effort. Trevali and Byrnecut, the mining contractor at Perkoa, also remain in daily communication with the families of the missing workers and we continue to offer our heartfelt support.

"The environment underground in any mine is dynamic, and our teams are working round the clock, adjusting methods and adapting to the circumstances we confront as we gain deeper access in the mine," said Ricus Grimbeek, President and CEO. "We will continue to make every effort, using all available equipment and personnel, and will continue to look for any and all opportunities to safely speed up the search operation. We acknowledge the frustration of the families and the community, and we are listening to their concerns. We are committed to locating our missing colleagues as soon as possible."

Summary of Dewatering and Mine Access Rehabilitation Efforts To-Date

The response to the flood event began on the morning of April 16 with the initiation of evacuation orders and mine rescue efforts, followed by immediate action to focus search efforts on dewatering and mine access rehabilitation to quickly gain access to lower levels of the mine.

A three-phase plan was initiated to dewater the mine. Phase One involved repurposing existing service water piping systems to support initial dewatering, sump pumping in the open pit, and establishing surface pump stations to receive water from the underground. This was quickly followed by Phase Two, which involved the rehabilitation of mine access and reconstructing the road surface to re-establish the mine's existing underground dewatering system that had been damaged by the flooding. Phase Three involved the installation of significant additional pumping and dewatering infrastructure, strainer boxes, and more than 5,000 metres of new poly pipe while simultaneously gaining access to the lower levels of the mine. In total, the multiple dewatering systems are comprised of more than 24 electric submersible and diesel pumps. A series of pumps is required in order to provide the pressure required to move the water from the lower level some 550 meters vertical to the surface.

As part of its efforts Trevali continues to source and transport additional machinery and equipment to the Perkoa Mine site, including installing pumps that arrived from Ghana by truck and from South Africa by air, expedited with the assistance of the Burkina Faso government and Air France. Other mining companies in Burkina Faso have provided support in the form of pumps and operational assistance. The National Fire Brigade has also been continually on site and has provided additional emergency response support and expertise.

Both the Company and the government are undertaking ongoing investigations into the circumstances that resulted in this flood event, and Trevali has welcomed visits from all government authorities who have requested site access. The Company fully supports an open and independent investigation and will provide any assistance that may be required.

The Company will provide further details on the progress of search activities as circumstances warrant.

Trevali Mining Corporation ("Trevali" or the "Company") (TSX: TV) (BVL: TV) (OTCQX: TREVF) ( Frankfurt : 4TI) provides an update on search efforts at the Perkoa Mine in Burkina Faso following an April 16 flooding event.

To date, approximately 32 million litres of water have been removed from the Mine and access has been restored to Level 550. There has been no communication with the eight missing workers since April 16 and none have been located yet. The Company continues to strengthen search capabilities with additional equipment and resources, and search crews will continue to work at maximum capacity, 24-hours-per-day to locate the missing individuals.

Throughout the search process, senior representatives of Trevali and Byrnecut, the mining contractor at Perkoa, have been in daily communication with the families of the missing workers and continue to offer support.

"We are working in solidarity with all levels of government and as fast as we possibly can using all available resources in the country, as well as importing additional machinery and equipment to assist with locating our missing colleagues," said Ricus Grimbeek, President and CEO. "Our thoughts are with our colleagues' families, and we continue to work closely with the families and the government to ensure their needs are met during this difficult time."

Added Mr. Grimbeek, "Trevali is appreciative of the support of the government and various agencies in Burkina Faso . We welcome the decision by the government to move its crisis management committee nearer to the mine site to better include family members of the missing workers and facilitate closer collaboration as we rapidly work to locate the missing individuals. We will remain closely engaged with government authorities to help the community respond to the impacts of the recent flooding."

The search effort requires the careful rebuilding of the road on more than 5,000 metres of underground decline ramp in order to facilitate the search efforts and safely install and operate pumping and piping infrastructure to remove floodwater. As of May 8 :

• Approximately 25,000 tonnes of waste rock has been used in rehabilitation of the mine access ramp

Trevali Mining Corporation ("Trevali" or the "Company") (TSX: TV) (BVL: TV) (OTCQX: TREVF) ( Frankfurt : 4TI) provides an update on search and rescue efforts for eight missing workers as well as progress made on mine rehabilitation and dewatering at the Perkoa Mine in Burkina Faso following intense rainfall that occurred in the early morning of April 16, 2022 and resulted in flooding of the mine.

Eight workers remain unaccounted for following the evacuation of the underground area of the mine and the Company is working closely with Burkinabe authorities as search and rescue efforts continue. Mining and milling operations at Perkoa will remain suspended for the foreseeable future as the Company investigates the cause of the flood event.

The Company initially reported the incident on April 16, 2022 , the date of the flooding. A second release was issued April 21, 2022 to provide an update on the Company's activities in response to the flooding of the mine and convey the initial assessment of events surrounding the flood event at the Perkoa Mine. The Company today provides a further update on its activities in response to the flooding of the mine, particularly the logistical operation behind the search and rescue efforts for the missing workers, which includes mine decline rehabilitation and dewatering activities.

"Our primary focus is the search for our colleagues and to do this we are getting pumping and other dewatering equipment where it is most needed," said Ricus Grimbeek, President and CEO. "The flood eroded the decline ramp that is the primary access to all levels of the mine and repairing this access ramp for safe use was a critical initial step in our efforts. With the completion of the decline rehabilitation to Level 520, pumping capacity has now increased, including the installation of a new 5,000-metre pipeline to surface with multiple teams of welders dedicated to completing the assembly and installation. Trevali's senior leadership and Byrnecut, Trevali's mining contractor at the Perkoa Mine, continue to meet with the families of the missing workers and to ensure they have everything they need in these difficult times. We are grateful for the valuable support from the Burkina Faso government and the broader Burkina Faso mining community who are providing all assistance possible in our search and rescue efforts."

The Company has had regular communications with, and received assistance from, the Burkinabe Ministry of Mines and Quarries, the National Emergency Rescue, Military Civil Construction, the Governor of Central-West Region, and the High Commissioner of Réo. A delegation from the government was provided a briefing at the Perkoa Mine site on April 23 . Representatives included the Minister of Mines and Quarries, the Minister of Environment, the Minister of Labour, the Minister of Religious and Cultural Activities, the Governor of Central-West Region and the President of the Chamber of Mines.

Additional updates:

• The water level in the mine has settled at approximately Level 520 (520 metres from surface). Communications and electrical power have now been re-established to Level 520.
  
  
• While most workers underground or preparing to enter the mine were able to safely evacuate, the eight missing workers were working below Level 520 at the time of the flooding and there has been no communication with these workers since soon after the evacuation order was given. There are two refuge chambers located below Level 520 that are designed to provide a refuge for workers trapped in a hazardous environment. We do not know if some or all of the eight missing workers were able to access these refuge chambers.
  
  
• The decline ramp roadway is the essential access for vehicles moving people and equipment between levels in the mine. The torrent of water entering the mine resulted in significant road surface erosion. Rehabilitation of the decline ramp is essential to allow the transport of larger pumps to Level 520 to increase dewatering capacity. The Company has completed approximately 3,643 metres of an estimated 5,000 metres of decline ramp rehabilitation the Company believes is required to gain access to lower mine levels, reaching the water level at Level 520 as of April 23 .
  
  
• The Company has a three-stage dewatering plan, of which the first two stages – the repurposing of existing piping to commence initial dewatering efforts, followed by the installation of additional underground pumping infrastructure to facilitate an increase in pumping capacity – are now complete and actively pumping. The third stage, which is currently in progress, involves the installation of 5,000 metres of new piping and higher-capacity pumps to increase pumping capacity. Multiple welding crews are mobilized for this assembly effort.
  
  
• The objective of the plan is to dewater the mine to continue the search and rescue efforts for the missing colleagues while working toward completely dewatering to the lowest level of the mine. The Company has also re-established sump pumping in the open pit and doubled pumping volume capacity as a precautionary measure while we continue to investigate the cause of the event.

The Company will provide further details on progress of search and rescue activities and site investigation as more information becomes available.
