Calgary, Alberta — September 8, 2026 — Leads & Copy — Rain City Resources Inc. (CSE: RAIN) has entered into an agreement with ZERO13, a GMEX Group company, to establish a strategic collaboration framework for the development of blockchain-enabled traceability, ESG verification, and institutional-grade digital infrastructure for critical mineral production. The agreement aims to create a framework capable of supporting certification from source to final product, encompassing product purity, water consumption, energy intensity, carbon performance, reagent usage, laboratory verification, batch identification, and chain-of-custody information. This initiative is seen as increasingly vital as lithium and battery supply chains grow more strategic, regulated, and complex.
Rain City Resources believes that transparent, verifiable, and auditable production data will become crucial for battery manufacturers, automotive OEMs, offtakers, regulators, institutional investors, and governments seeking secure, sustainable, and traceable critical mineral supply chains. The Company intends to position itself at the forefront of these technological advancements.
The Company’s strategy involves moving beyond a purely extractive approach to contribute to a regional ecosystem where science, technology, sustainability, capital, and institutional trust can operate collaboratively and transparently. This emerging platform is designed to foster a more integrated and cooperative model among stakeholders in the lithium value chain, including governments, public entities, universities, research centers, technology providers, local communities, investors, offtakers, and industrial partners.
Benjamin Hill, Chief Executive Officer of Rain City Resources, stated that the agreement signifies a crucial step in the Company’s evolution. He emphasized the belief that by providing ESG and chain of custody transparency in lithium extraction, Rain City will lead responsible Direct Lithium Extraction (DLE) practices. Through collaboration with ZERO13 and GMEX Group, Rain City aims to build the necessary digital infrastructure to ensure trust from the outset of the production process.
Sebastián Quiñones, Head of Rain City Resources Latin America, highlighted the strategic importance of the alliance, connecting Rain City’s lithium extraction platform with trusted digital verification, a key frontier in global market infrastructure. He views the Lithium Triangle not merely as a source of raw materials but as a potential platform for scientific validation, responsible production, digital traceability, institutional cooperation, and novel sustainable finance mechanisms. Rain City has been actively building connections between leading universities, research centers, public entities, technology providers, and capital markets to strengthen the lithium ecosystem through a more collaborative, transparent, and disruptive model.
In other developments, Rain City Resources announced the mutual extension by 90 days of the exclusivity period with Ion Source LLC, stemming from a Term Sheet executed on April 16, 2026. Benjamin Hill noted the close collaboration between Rain City and Ion Source since April to develop their AC²ME DLE technology and other commercial applications. He expressed satisfaction with the ongoing strong, collaborative relationship.
