NEWS RELEASE

CREST RESOURCES MAKES INVESTMENT IN NEW CLASS OF MINERAL RECOVERY REAGENTS

Vancouver, B.C. – April 1, 2020 ‐ Crest Resources Inc. (CSE: CRES) (the “Company”) is pleased to announce

an agreement (the “Agreement”) to invest up to $1,000,000 in EcoMine Technologies Corporation

(“EcoMine”), a private British Columbia company that produces targeted bio-chemical reagents for

recovery of metals in the mineral industry . The Company, together with such pa rties agreeable to

EcoMine, will purchase an aggregate 4,000,000 common shares of EcoMine at a price of $0.25 per share

(each, a “Share”) for total investment of $1,000,000 in four tranches over 18 months.

EcoMine was founded to create new mineral recovery solutions in what is generally considered a mature

industry that has neglected R&D and is ripe for technological advance. EcoMine is developing a portfolio

of protein based, engineered mineral recovery reagents which can increase metal recoveries from existing

mining operations, and in new mining operations. The use of Ecomine’s patent pending technology can

increase revenue, reduce capital and operating costs and, reduce environmental impacts. Further, this

technology addresses fine contaminates in wastewater streams in mining and other industrial

applications. The mineral processing reagent business is an annual $95 billion dollar business , with an

annual $60 billion dollars of reagent production that is targeted by the EcoMine platform.

Subsequent to the first closing, the Company has agreed to work together with EcoMine to achieve a

public stock exchange listing for EcoMine by way of IPO, RTO, statutory amalgamation, M&A transaction

or similar transaction within 30 months from the date of the First Closing.

Crest sees exceptional potential to leverage value in m ineral projects that respond poorly to traditional

recovery technology but are well suited to the EcoMine reagents. Crest and EcoMine are actively working

to secure access to, test and develop recovery flow sheets that will unlock value in these neglected mineral

deposits. Not only is this a step change in the development of stranded mining assets on a global scale, it

represents an exceptional investment opportunity for Crest going forward.

President and CEO Michael Collins comments, “Crest is excited to bring EcoMine to the market and help

develop its operations and deployment in the mining industry. EcoMine is Crest’s initial investment in

mining technology. EcoMine provides solutions for today’s world through increased mining efficiency and

cleaner water and has the potential to be very profitable doing so. Crest continues to work on a pipeline

of opportunities that will be additionally rewarding for its shareholders.”

ABOUT THE TRANSACTION

The Shares will be acquired by way of private placement in four tranches of 1,000,000 Shares each as

follows: The First Tranche shall close in the second quarter 2020 (the “First Closing”), with each

subsequent investment to close on or before the six, twelve and eighteen month anniversary of the First

Closing. The closing dates of the subsequent investments may be revised as agreed by the parties,

depending on the cash needs of EcoMine. A non-refundable deposit of $25,000 was paid by the Company

upon signing the Agreement and the Company agreed to advance $250,000 towards the First Tranche as

an interest free unsecured loan until completion of the First Closing. Crest has the right to represent

EcoMine in market development as both companies work to build a strong market for EcoMine’s products.

{01549466;1}

A further condition prior to the First Closing is that the Company shall nominate a person that shall be

appointed to the board of directors of EcoMine.

ABOUT ECOMINE TECHONOLOGIES CORPORATION

EcoMine, a B ritish Columbia based company, is a world leader in the development of breakthrough

proprietary bio-chemical reagents for the global resources sector. EcoMine’s technology platform opens

up entirely novel, environmentally benign mineral processing chemistries - potentially the largest single

improvement in mining reagent chemistry in nearly eight decades.

The Company is now on the cusp of multiple market-ready solutions that are customizable across a broad

range of processing applications to improve the recovery profiles of existing operations and to unlock

value from different types of resource assets where viable off-the-shelf chemistries don’t already exist.

The first phase of EcoMine’s technology is a suite of high affinity, high selectivity biochemical reagents for

precision separations, applicable to hard -to-process deposit types across the gl obe. After two years of

product development and testing, EcoMine applied for its first patent on this technology portfolio in 2019

against proven applications in copper and gold processing. In a second phase of development, the

company is now developing a separate proprietary biochemical portfolio for metal ion recovery

applications. As both platforms advance, EcoMine will develop increasingly sophisticated discovery tools,

based on in-silico AI and high-throughput empirical validation. In the longer term, this body of science has

the potential to address multiple industrial separation challenges beyond the mining sector , including

advanced materials fabrication, production of “smart” construction materials, and environmental sensing.

EcoMine was founded by Robert Greene and John Davies. Robert Greene is a specialist in applications of

biotechnology to mineral processing and hydrometallurgy and the inventor of EcoMine’s technology

platform. Joh n Davies built his career in the commercialization of early stage science, creating and

supporting businesses that came to be worth over $2 billion in aggregate.

EcoMine has partnered with Crest Resources for the next stage of its evolution, to accelerate the adoption

of the platform. The Crest team has a wealth of experience across the resources sector and is uniquely

positioned to help EcoMine identify acute challenges in the industry where EcoMine’s technology can

generate high impact returns.
