Vancouver, British Columbia – (May 26, 2021) – Battery Mineral Resources Corp.

(TSXV: BMR) (" Battery" or the " Company") is pleased to announce that it has

completed its acquisition of ESI Energy Services Inc. (" ESI") concurrent with the

completion of ESI’s previously announced going private transaction. The result is that

Battery, which owned 89.2% of the ESI common shar es before the share

consolidation, now owns 100% of the ESI common shares. ESI has applied to the

Canadian Securities Exchange to delist its common shares and has applied to

applicable Canadian provincial securities regulatory authorities to cease its reporting

issuer status.

ESI is a pipeline and renewables equipment rental and sales company with principal

operations in Leduc, Alberta and Phoenix, Arizona. ESI, together with its operating

subsidiaries, ESI Pipeline Services, Inc. and ESI Energy Services (Australia) Pty Ltd.,

are in oil and gas with an increasing presence in the renewable energy marketplace

where their products and service are used to construct wind and solar power

generation farms.

Commenting on the ESI Acquisition, Martin Kostuik , Chief Executive Officer of the

Company, said: “We are excited to have completed the agreement to add ESI to our

portfolio. This transaction represents a unique opportunity to add immediate cash

and positive cashflow to Battery. Consideration of offers to sell the business are on

the table. While considering options to monetize, t he focus for this new segment of

Battery will be to initiate strategies intended to increase the value of this business to

Battery shareholders. These strategies may include, among others, the sale of non-

core assets, improvement of margins by reducing costs such as corporate overhead

and investigating opportunities to increase revenue through expanding the product

and services offerings. We look forward to continuing to advance our corporate

strategy by realizing the value of our current projects for our shareholders while

bolstering our platform with additional accretive investments in this exciting and

growing space.”

cancelled them. The cash payment to each minority shareholder of $0.75 per

share is based on the number of ESI common shares held by minority

shareholders before the share consolidation.

before the share consolidation, now owns 100% of the ESI common shares.

• The transaction was approved by ESI shareholders at a special meeting earlier

yesterday. Votes were cast at the meeting by the holders of 93.76% of the ESI
