Dundee Sustainable Technologies Inc. Announces a $1.5 million Project with KSM Inc.





MONTREAL, QUEBEC / TheNewswire / December 24, 2018 - Dundee Sustainable Technologies Inc. (the "Corporation" or "DST") (CSE: DST) is pleased to announce a $1.5 million technical services project with KSM Inc.

DST will provide to KSM the construction of specialized equipment, senior engineering support and bulk processing of mineralized material. This work will support an industrial demonstration using KSM Inc.'s proprietary process for the extraction of fertilizer products from the serpentinic tailings in Thetford Mines, Quebec. DST developed a standard price quote for these services based upon scope of services request provided by KSM. This transaction is a related party transaction by virtue of common management between DST and KSM.

KSM's technology was originally developed by DST, but the Corporation discontinued development in 2015 as it was no longer a core activity. Instead, DST focused all of its resources to the gold extraction and arsenic businesses. In 2017, DST sold and transferred the patent and intellectual "know-how" of the fertilizer technology to KSM. In exchange for the patent and this "know how", DST received a cash payment and a 5% equity stake in KSM.

KSM Inc. is a privately-owned company based in Thetford Mines whose objective is to commercialize an innovative process for the production of fertilizers. KSM's technology uses potash and sulfuric acid to produce potassium and magnesium sulphate (SOPM) and potassium sulphate (SOP), two high-end fertilizers. Hydrochloric acid is also produced as a by-product. The requisite magnesium may be found in the serpentinic tailings present in large quantities in the Thetford Mines area.

Mr. Brian Howlett, the CEO of DST commented, "The Corporation is pleased to provide technical services of this scope and scale to KSM as well as others in the mining business. These types of contracts are key to the utilization of our state-of-the-art pyro and hydro-metallurgical facility."
