Exploring a Responsible Future for Ekati

MicroMining Technologies Inc. is evaluating opportunities to apply advanced oxidation and integrated water-treatment technology to selected environmental challenges at the Ekati Diamond Mine, alongside a separate, conditional review of site assets and infrastructure.

Historical context

A nationally significant mining site

Located about 300 kilometres northeast of Yellowknife in the Lac de Gras region, Ekati began diamond production in October 1998. Burgundy historically reported 122 mining leases totaling approximately 113,485 hectares, with developed pits, underground workings, processing infrastructure, worker accommodation and water-management systems. Ekati is an important part of the history of Canada's northern diamond industry.

Current legal and operating status

Under court receivership

The operating companies entered insolvency proceedings in May 2026. On July 14, 2026, PwC was appointed court receiver. The receiver has reported that mining operations ceased and that current priorities include care and maintenance, environmental protection and planning for reclamation and closure. MMT's project interest is preliminary and does not change these obligations or imply control of the site.

Opportunity under evaluation. No MMT acquisition, approved project, pilot award or site-management contract has been announced. Any pilot, access, commercial arrangement, acquisition or restart is contingent upon engagement with the receiver, stakeholders, regulators, financing and approvals.

Approach

Two complementary avenues

Avenue 01

Environmental technology assessment

Review representative site water chemistry, existing treatment assets and discharge criteria; undertake independent laboratory treatability testing; and evaluate whether a properly engineered AOP module delivers measurable incremental benefits.

Avenue 02

Conditional asset diligence

Subject to receiver engagement, regulatory requirements and access to information, evaluate selected infrastructure or mining interests without assuming that assets are available for purchase or liabilities can be transferred or excluded.

Rationale

Why MMT is evaluating Ekati

Ekati combines substantial historical mining infrastructure with a complex Arctic environmental setting. Its existing water-management systems and ongoing closure planning make it an appropriate candidate for a disciplined, site-specific assessment of technologies that may complement conventional treatment and monitoring.
