Blencowe Resources has used a hypersonic rocket test in New Mexico to argue that its Orom-Cross graphite can reach higher-value aerospace and defence markets, but the technical claims remain company-reported and are not independently verified in the evidence pack. The London-listed miner said graphite from Orom-Cross was used across several components in a Pluto Aerospace solid-fuel rocket programme in Las Cruces on 18 August, alongside American Energy Technologies Co, Purdue University and US government agencies. The shares were unchanged at 8.15p on 1 September, giving the company a market value of £40.13m on the delayed quote used in the evidence pack.
The test matters because graphite is not being discussed here as a bulk industrial input. Blencowe is trying to show that Orom-Cross can supply specialist products for aerospace and defence applications where performance requirements are tighter and customer qualification is harder. According to the company’s announcement, the rocket reached Mach 5.5 and acceleration approaching 150G, which Blencowe said was a substantial increase from the April test programme. That is encouraging from a project-marketing standpoint, but investors should note the claims come from Blencowe’s own release and the pack does not provide third-party confirmation.
The company also said its graphite was used in an ablative rocket nozzle insert, anti-friction and ice-phobic coatings on four aluminium fins, and the lithium-ion battery powering the altimeter. Those are specific, practical uses, which is more meaningful than a generic claim that graphite can be used in “advanced applications.” In other words, the company is trying to demonstrate processability and product fit, not simply resource size. For a pre-production graphite asset, that distinction matters because downstream users care about consistency, purity, and manufacturability as much as geology.
Blencowe said its technical partner American Energy Technologies Co manufactured nozzle mouldings that replaced a proportion of the synthetic graphite normally used in these applications. That is important because synthetic graphite is often associated with high-performance use cases, so replacing part of it with material derived from Orom-Cross suggests a degree of substitution potential. The company also said the resultant nozzles underwent rigorous testing before installation on the rocket. Again, that supports the narrative of technical qualification, but the evidence pack does not include details of the test protocol, the pass criteria, or whether any independent lab reviewed the results.
The battery-related disclosure adds another layer. Blencowe said the altimeter battery used 3.8 Ah pouch cells by Navitas Systems, up to 15 wt.% recycled “healed” graphite, and zero synthetic graphite. That points to a different part of the product mix, where recycled graphite and processed material may have been incorporated in a battery system supporting flight instrumentation. For investors, the practical takeaway is that Orom-Cross is being tested across multiple end uses rather than a single niche. The caution is that the battery claim, like the rocket-performance claims, is still a company statement until independently validated.
For graphite developers, the main commercial question is not whether a rock contains graphite. It is whether the material can be converted into products that match end-user specifications at scale and at acceptable cost. Blencowe is clearly positioning Orom-Cross toward that higher-margin end of the market. Cameron Pearce, the company’s executive chairman, said the results continue to highlight Orom-Cross as an important source of high-quality graphite products for military and aerospace applications. He also said there are relatively few graphite projects worldwide capable of supplying the quality required for these specialist applications.
Those comments should be read as strategic positioning rather than independent market analysis. Still, the logic is straightforward. If a project can qualify for demanding applications, it may open doors to offtake relationships that are more valuable than standard industrial sales. That said, qualification is only one step. A company still has to prove repeatability, secure funding, build production, and satisfy customers on delivery, pricing and consistency. None of those steps is solved by a successful test flight.
Pearce also linked the testing work to the funding and build-out of P1 production, saying Blencowe is completing funding for P1 Production and moving to the first stage of operations while continuously testing new products and adding new offtakers. That sentence is the real commercial anchor in the story. Testing can support a development thesis, but cash is what moves a project from promise to plant. Investors should therefore treat the aerospace data as one more input into the financing and offtake story, not as evidence that the project is de-risked in a broader sense.
This is especially relevant because the company is still advancing toward first production. The evidence pack does not provide a production timeline, capex total, or funding gap, so those key questions remain outside the scope of this article. What is clear is that management is trying to differentiate Orom-Cross from other graphite projects by targeting lucrative applications and strategic relationships. That is a rational approach in a market where commodity projects can struggle to stand out, but the strategy only works if technical qualification converts into binding commercial agreements.
The announcement was dated 1 September 2026, and the rocket test took place on 18 August 2026 in Las Cruces, New Mexico. Attendees included AETC, Pluto Aerospace, Purdue University, US government agencies, and Blencowe COO Iain Wearing. The company said the initial testing programme is being undertaken with Pluto Aerospace for hypersonic sub-orbital rockets, with orbital testing planned for the final quarter of 2026. That gives investors a near-term milestone to watch. If future tests continue to use Orom-Cross material in working hardware, it would reinforce the case that this is more than a one-off promotional exercise.
Even so, the evidence pack is explicit that all performance and technical claims trace to Blencowe’s own RNS, with no independent third-party validation. That limitation should stay front and centre. In mining, especially in emerging specialty products, the line between a credible technical pathway and an investable commercial pathway can be wide. Successful test use is helpful, but it does not replace a feasibility study, customer qualification programme, or signed offtake contract.
The near-term questions are practical. Can Blencowe convert these aerospace and defence tests into repeat orders or formal customer relationships? Can the company keep funding P1 production while continuing to prove product quality? And can Orom-Cross maintain credibility if later tests are less dramatic than a Mach 5.5 rocket flight? Those are the issues that will determine whether this becomes a niche technical success or a material business opportunity.
For now, the stock market is not assigning a dramatic valuation response. Blencowe’s shares were flat at 8.15p on the quoted date, and the market cap in the evidence pack was £40.13m. That suggests investors are waiting for more than headlines. The next meaningful evidence point is likely to be the planned orbital testing in the final quarter of 2026, where repetition and consistency will matter more than speed alone.
