Ione, CA – April 10, 2025 – Purebase Corporation (OTCQB: PUBC), a leader in sustainable mineral-based solutions for agriculture and construction, is pleased to announce the international shipment and sale of Humate Advantage to Pakistan for agricultural applications. This marks a significant step toward the goal of selling Humate Advantage into the Asian and Central and South American continents, in addition to the United States.

Developed and tested, Humate Advantage is an organic soil amendment derived from naturally occurring leonhardite deposits, designed to enhance soil fertility, improve nutrient retention, and support healthier crop growth. With increasing global interest in sustainable farming practices, Purebase sees tremendous potential for Humate Advantage in regions where soil health is a pressing concern.

“Our international expansion underscores our commitment to providing sustainable solutions to the agricultural industry,” said Scott Dockter, CEO of Purebase Corporation. “Pakistan’s diverse agricultural landscape presents an ideal opportunity to demonstrate the benefits of Humate Advantage in improving soil conditions and crop yields. This gives us an opening into agricultural markets in other nearby countries, as well.”

The performance of Humate Advantage will be assessed across various soil types and crops in Pakistan, working closely with local agronomists and farmers to optimize application methods. These trials are part of a broader strategy to establish Humate Advantage as a commercially viable solution for farmers seeking to improve soil health and productivity while reducing dependency on synthetic fertilizers.

Purebase provides its blended supplementary cementitious material to UC Davis Pavement Research Center for concrete test track

Purebase provides its blended supplementary cementitious material to University of California Pavement Research Center for concrete test track

IONE, CA, AUGUST 29, 2024 (GLOBE NEWSWIRE) — Purebase Corporation (OTCQB: PUBC), a natural resource development company headquartered in Ione, California, is pleased to announce that the UC Davis Pavement Research Center (UCPRC) will be utilizing Purebase’s blended metakaolin supplementary cementitious material in its upcoming concrete pavement test track this summer or early fall 2024.

UCPRC launched the Sustainable Concrete Lab-to-Slab Initiative, focused on evaluating low-carbon cements and supplementary cementitious materials beyond the traditional coal fly ash and slag. This initiative is supported by organizations such as the ACI Foundation, the California Department of Transportation (Caltrans), and the Federal Highway Administration (FHWA)’s Sustainable Pavements Program Cooperative Center (SPPCC).

The Sustainable Concrete Lab-To-Slab Initiative aims to advance sustainable concrete technology by accelerating the implementation of more sustainable binders for structural, pavement, minor, and other concrete applications.

According to UCPRC website, the objective is to construct a series of three successive slabs, each utilizing a novel sustainable material for concrete, with a minimum requirement of approximately 2.5 cubic yards of concrete per test section. This initiative aims to generate invaluable insights at small-scale (no-traffic) test sections into the viability and efficacy of these materials for real-world applications in pilot projects and mainstream construction.

“Through prequalification testing, constructability assessment, QA/QC testing, mid-term monitoring, and environmental and cost life cycle assessment, we are dedicated to evaluating the performance of these materials and helping government and private project owners accelerate their implementation,” said the UCPRC.

“Although UC Davis has tested metrics of our SCM in the past in a lab setting, this is the next step in a project by the UCPRC where we can physically see the performance of the material in a real-life application. If testing of Purebase’s SCM is successful in the concrete pavement test slab, this will open the door for our SCM to be widely utilized and implemented in substantial construction projects across the state of California,” said Purebase CEO, Scott Dockter. “This would be a positive move for Purebase in our goal of decarbonizing California, and eventually, the nation.”

Purebase promotes Joe Thomas to advisory board chairman

Purebase promotes Joe Thomas to advisory board chairman

IONE, CA, MARCH 13, 2024 (GLOBE NEWSWIRE) — Purebase Corporation (OTCQB: PUBC), a natural resource development company headquartered in Ione, California, announces the appointment of Joseph Thomas as chairman of its advisory board, in addition to his services as a consultant to Purebase. Purebase’s executive leadership has carefully sought out leading science experts whose work is in alignment with our product development efforts focusing on supplementary cementitious materials (SCMs).

 

Mr. Thomas has over 30 years of experience with cementitious materials, focusing on SCMs, natural pozzolans, blended cements, lightweight cements, ultrafine cementitious grouts, lightweight aggregates, and the remediation of non-spec waste products, which have cementitious value.

 

Since 2013, Mr. Thomas has been the owner of Magmatics, Inc., a consulting firm focused on pozzolanic and cementitious materials product development, oil field cementing, concrete mix design, and concrete admixtures. Prior to this, he served as Vice President of Research & Development at Hess Pumice Products, a pumice mining and processing company where he helped develop their various natural pozzolan products and helped to establish their marketing/sales footprint in Asia and Europe, as well as across North America. Mr. Thomas graduated from the University of Idaho (Moscow) with a Bachelor of Science degree in 1982. He is currently the Executive Dir­ector of the Natural Pozzolan Association (NPA), the Chair of the American Concrete Institute’s (ACI) 240 Pozzolan Committee and serves as the Natural Pozzolan Task Group Chair at the American Society for Testing and Materials (ASTM). He is responsible for 9 patents related to pozzolans and remediated SCMs in the cementitious materials industry.

 

“The rapid development of high-performance, pozzolanic, supplementary cementitious materials are the preeminent focus of research in the cement & concrete industries today,” Joe Thomas stated. “Only with sustainable, low-carbon cement replacements can the concrete industry drastically lower its significant carbon footprint, and importantly, increase the durability of concrete at the same time; a win-win opportunity for the industry and for the built environment. Repurposing Purebase’s significant legacy mining-waste assets into high-value SCMs is a no-brainer.”

 

“Joe Thomas stands as a vitally important consultant and innovator in Purebase’s line of work as we continue moving forward with our product development in the SCM market,” states Purebase CEO, Scott Dockter. “Having the very unique background that Mr. Thomas holds in this industry, I believe his position as chairman of our advisory board will accelerate the progress of our company’s developments as we aim to be a solution provider to climate issues.”
