Greenvale Energy has completed initial product assessments for its Alpha Project bitumen samples, successfully separating volatile fractions and producing a bitumen-like material. The company plans further processing to meet industry specifications and awaits independent certification.
- Initial assessment confirms bitumen-like product after volatile removal
- Vacuum distillation improves penetration but viscosity remains below spec
- Technix's Multistage Bitumen Process (TMPB) targeted to meet C-170 standard
- Alpha Project holds 28Mt resource equating to 27.7 million barrels synthetic oil
- Independent certification planned upon successful processing
Initial Assessment Validates Bitumen Potential
Greenvale Energy Limited (ASX:GRV) has reached a key milestone in its Alpha Project, with Technix completing the initial assessment of product samples derived from Monash University. The test program confirmed the successful separation of light-end volatile hydrocarbons, producing a product that behaves like bitumen. This is a critical step toward developing a synthetic bitumen product from the project's 28 million barrels of synthetic oil equivalent resource.
The initial samples exhibited a low flash point of 15°C, indicating elevated volatile content well below typical bitumen standards (>250°C). Through atmospheric and vacuum distillation, Technix removed approximately 35-40% volatile hydrocarbons, bringing the flash point into compliance with the C-170 bitumen specification. However, while penetration values after vacuum distillation fell within acceptable ranges, viscosity at 60°C and 135°C remained below specification, highlighting further processing needs.
Next Phase: Multistage Bitumen Process to Enhance Properties
To address viscosity shortcomings, Technix has recommended applying its Multistage Bitumen Process (TMPB), which uses additional reagents and additives under pressurised conditions to improve bitumen feedstock characteristics. Greenvale is currently awaiting a detailed quote and test plan to commence this phase, underscoring its commitment to advancing the product development.
Upon successful TMPB treatment and internal confirmation of meeting C-170 specifications, Greenvale plans to submit samples to Intertek Laboratories for independent certification. This step is vital for market acceptance and regulatory compliance, positioning the Alpha Project as a potential domestic source of bitumen amid tightening supply conditions.
Alpha Project’s Resource and Test Program Context
The Alpha Project hosts an inferred mineral resource of 28 million tonnes comprising Torbanite and Cannelite, equivalent to 27.7 million barrels of synthetic oil, reported under the JORC Code (2012). The project’s test program 7 (TP7) has focused on optimising conversion and solvent recovery, achieving ~99% torbanite conversion and ~98.9% solvent recovery, streamlining the toluene-based processing route.
Greenvale’s Managing Director Alex Cheeseman highlighted the progress, noting the successful splitting of the light-end fraction and the derivation of a bitumen-like product. The company remains encouraged by these developments and plans to keep the market updated as the final phase of processing advances.
Bottom Line?
Greenvale’s next challenge lies in successfully applying Technix’s TMPB to meet viscosity specs and secure independent certification, critical steps before commercialisation.
Questions in the middle?
- Will the TMPB process fully resolve viscosity shortfalls to meet C-170 standards?
- How soon can Greenvale advance to independent certification and what are the potential bottlenecks?
- What commercial timelines and market opportunities emerge once product specification is confirmed?
