Pulsar Helium expands Minnesota acreage by 1,000% in all-share Quantum Hydrogen deal, preserving cash for flagship Topaz helium project.
This article covers information on Pulsar Helium Inc..
LON:PLSRPulsar Helium has signed a non-binding term sheet to acquire up to 100% of Quantum Hydrogen Inc., adding 59,100 gross acres of non-hydrocarbon gas mineral rights in Minnesota. The land sits in St Louis and Itasca Counties, to the west of Pulsar’s flagship Topaz project. If completed, the deal would boost Pulsar’s Minnesota footprint by circa 1,000% and extend its hunt for primary helium in a familiar geological setting.
This is an all-share transaction with no cash outlay, which fits neatly with Pulsar’s stated priority: preserve cash to advance Topaz into production while building a longer-term exploration pipeline nearby.
The company plans to acquire 80% of Quantum initially, with an option to take the remaining 20% within 18 months. Quantum holds exclusive mineral rights for non-hydrocarbon gases over 59,100 gross acres. That is a big step-up in potential running room, adjacent to an area where Pulsar already has momentum.
Why it matters: the new ground is considered prospective for helium and hydrogen and shares key geological traits with Topaz. Pulsar believes it can apply what it has learned at Topaz – on helium generation, migration pathways and structural traps – to a conventional sedimentary reservoir setting here. In short, it is a scale-up of the same playbook, in the same region.
Topaz is a helium discovery associated with fractured Archaean basement rocks. The newly targeted acreage sits in a non-hydrocarbon-bearing sedimentary basin over that same type of basement. The model is straightforward: helium generated in basement granites migrates upwards and accumulates in overlying sedimentary reservoirs, which are then sealed by mudstone and siltstone layers.
That is useful for Pulsar because it reduces the learning curve. The company’s recent technical work at Topaz has focused on mapping where helium is generated and how it moves. Applying that understanding across a much larger licence position could make future exploration more efficient and lower risk compared with stepping out into a brand new basin.

Pulsar is adamant that Topaz remains front and centre. The company recently reported strong testing at the Jetstream #1 appraisal well and intends to start a multi-well drilling campaign in late September 2025. By structuring the Quantum acquisition entirely in shares, management keeps cash free for Topaz workstreams that are intended to unlock near-term production.
Importantly, Quantum is early stage. It has no revenue and no reserves or defined resources. Management does not expect any material impact on Pulsar’s financials or resource base in the near term. Think of this as a low-cost, option-style land grab next door to the main event.
These datapoints underpin the geological rationale for expanding westwards. If Topaz can demonstrate commercial deliverability, similar rocks nearby become compelling targets.
This looks like a sensible bolt-on. Pulsar is doubling down on what is working – Minnesota helium in a proven geological setting – without distracting cash away from Topaz. The price tag is modest, paid in shares, and the structure keeps risk in check with an 80% initial stake and an option on the rest.
The flip side is that none of this is de-risked yet. The term sheet is non-binding, the assets are early stage, and there is no near-term uplift to resources or revenue. For sentiment, the bigger driver remains Topaz, where 14.5% helium and a 1.3 mmcf/d peak flow suggest real potential. If Topaz delivers, this enlarged acreage could become a meaningful second act. If not, this is cheap exposure rather than a costly mistake.
Net-net, I view the announcement as incrementally positive: it reinforces the Minnesota thesis, preserves cash for the main project, and expands the opportunity set at a low entry cost. Execution at Topaz will dictate how valuable this land grab ultimately becomes.
Impax Q3 AUM rises to £23.3bn despite £1.7bn net outflows, driven by market gains and strong investment performance.
