Greenvale Achieves 40x Scale-Up in Alpha Project, Bulk Sample Production Underway

Milestone Achievements and Scaling Success

Greenvale Energy Limited (ASX, GRV) has announced significant progress in its Alpha Torbanite Project in Queensland, successfully completing the first two milestones of its Test Program 7 (TP7). This phase has notably achieved a 40-times volumetric scale-up from previous test work, a critical technical hurdle in mineral processing that validates the repeatability and robustness of their process at a much larger scale.

CEO Alex Cheeseman highlighted the importance of this achievement, noting that the specialist equipment designed and commissioned in collaboration with Monash University has confirmed the ability to produce an asphaltene-based product consistently. This success sets a strong foundation for the next stage of the program.

Bulk Sample Production and Certification Goals

With the initial milestones met, Greenvale has commenced bulk sample production as of December 2025, scheduled to run through to late February 2026. This bulk sample is sourced from carefully selected drill core intervals representing the resource’s lithology and seam characteristics. The program aims to produce a commercial bitumen product that meets the independent C-170 asphalt specification, a recognized industry standard for bituminous materials.

The involvement of Technix, a bitumen processing specialist, will be crucial in the final processing and certification stages. Achieving C-170 certification would mark a major commercial milestone, potentially unlocking significant value for shareholders and positioning the Alpha Project as a viable supplier of bitumen products.

Technical Insights and Project Context

Test Program 7 builds on learnings from previous phases, particularly TP6, which identified optimal process controls such as temperature ramping to 400°C, pressure conditions, and catalyst use (notably zinc) to maximize product yield. The process involves rapid heating under high pressure in an oxygen-free environment, a combination that required bespoke equipment to replicate at scale.

The Alpha Torbanite Project itself boasts an inferred mineral resource estimate of 27.7 million tonnes, with the deposit comprising cannel coal and torbanite lenses within the Permian Colinlea Sandstone. The project’s geological setting and resource scale underpin its potential as a sustainable source of bituminous material.

Outlook and Strategic Implications

Greenvale’s progress with TP7 and the bulk sample production phase signals a transition from laboratory-scale testing to a more commercially relevant scale. While delays in equipment procurement were encountered, the company has extended the program timeline without additional cost, reflecting a pragmatic approach to ensuring thorough validation.

Success in this phase could pave the way for further development, including potential market entry for the bitumen product and exploration of additional product specifications. The company’s focus on sustainable, low-carbon energy resources aligns with broader industry trends, potentially enhancing its appeal to investors and partners.
