VANCOUVER, BC / ACCESSWIRE / May 11, 2023 / CoTec Holdings Corp. (TSXV:CTH)(OTCQB:CTHCF) ("CoTec" or the "Company") is pleased to announce it has invested US$1.5 million into Ceibo Inc. ("Ceibo"), a Delaware corporation, for a small equity interest. Ceibo, through its wholly-owned Chilean subsidiary has developed a revolutionary process to leach low-grade primary copper sulphides, such as chalcopyrite, and copper waste material using a proprietary high throughput inorganic leaching technology. Jetti Resources LLC, a copper mining extraction company has developed a competitive, though more advanced, technology which has recently been valued at USD2.5 billion.^[1]

CoTec participated in Ceibo's recently completed Series B financing round with funding secured from a group of leading international investors. Ceibo will use the proceeds from the financing to scale its technology through continued small- and large-scale column testing and the building of a demonstration plant.

If successful, Ceibo's technology will represent a leading, low-carbon, high recovery primary and waste copper sulphide heap leaching process. This could deliver considerable value through a significant reduction in the time required to bring additional copper into production, a competitive cost structure and a lower environmental and carbon footprint, protected by a high technical barrier to entry.

Julian Treger, CoTec CEO commented: "We are pleased to have been given the opportunity to invest in Ceibo. In line with CoTec's business model, we expect to contribute to the development of the technology by appointing a representative to a Technical Advisory Board that Ceibo intends to form. We also intend to identify opportunities for Ceibo to commercially deploy its technology with a view to participating in any such opportunities that Ceibo chooses to pursue as a co-investor or joint venture partner.

"Entering the copper industry has been one of CoTec's key strategic objectives and we view Ceibo's technology as an excellent entry point for us as copper will play an essential role in the transition towards a carbon-neutral energy system. We are looking forward to working with the Ceibo team as they continue to develop this exciting technology and in securing application opportunities that we could jointly pursue.

"Our board and senior executives have extensive experience and industry relationships that, along with the financial support of our co-investors, will allow CoTec to make a meaningful and immediate contribution to Ceibo's success."
