Ascent Resources secures option on lithium and potash brines in Utah’s Paradox Basin

Ascent Resources has signed an option agreement that could turn its existing US oil and gas acreage into a new revenue stream from critical minerals. Together with partner American Helium (AH), the company has granted Neometals (NMT) and Omaha Value (OMA) a 60-day exclusive window to negotiate a definitive licence over Ascent/AH’s wells and leases in the Paradox Basin, Utah. The goal: explore and potentially extract lithium and potash from mineral-rich brines already encountered historically during oil, gas and helium drilling.

It is early days – an option, not a binding development deal – but the structure looks capital-light and designed to monetise sunk infrastructure. That’s worth a closer look.

What exactly has been agreed and who’s involved

The Option Agreement gives NMT/OMA exclusivity for 60 days (extendable by mutual consent) to negotiate access and use rights over Ascent and AH’s portfolio in Utah. If it progresses, NMT/OMA would be responsible for exploring the brines for lithium and potash and potentially developing extraction. Ascent describes this as a new monetisation pathway with no upfront drilling or development cost to the company.

Commercially, the fees are payable by NMT/OMA and shared between Ascent and AH according to their current interests in the portfolio – Ascent 49% and American Helium 51%. The structure includes fixed fees and a royalty on any future brine production revenue.

Why this matters: critical minerals, low capex, faster routes

No upfront drilling or development cost to Ascent – the big appeal for shareholders wary of dilution.
Brines were previously intersected during historic hydrocarbon and helium exploration, so this leverages known subsurface fluids rather than starting from scratch.
Using existing wellbores and infrastructure should reduce time and cost compared with drilling new wells.
Lithium and potash have “critical mineral” status in the US, which may support accelerated permitting and potential federal funding – helpful tailwinds if they materialise.

Key commercial terms at a glance

Term	Gross (US$)	Ascent’s 49% share (US$)
Exclusivity fee (payable within five business days)	50,000	24,500
Option exercise fee (if exercised)	50,000	24,500
Permitting fee (on grant of relevant mineral leases; pro-rated if fewer wells)	1,900,000	931,000
Annual licence fee (payable in arrears)	200,000	98,000
Royalty on future brine production	2.5% of gross revenue, rising to 3.5% if commercial extraction has not commenced within five years of mineral lease grant	Ascent entitled to 49% of royalty receipts

Important: these are gross terms to the Ascent/AH partnership. The permitting fee is only triggered on grant of the relevant mineral leases, and the annual licence fee is payable in arrears. The royalty only kicks in if there is commercial brine production.

Strategic angle: multi-commodity value from existing acreage

Ascent is positioning its Utah/Colorado footprint as a multi-commodity platform: hydrocarbons, helium, potential CO2 sequestration, and now critical mineral brines. This optionality matters. It diversifies potential revenue and uses sunk infrastructure more efficiently.

Partnering with Neometals (a lithium-focused developer) and Omaha Value (a local partner) is sensible. If they proceed, Ascent gets a share of fixed fees and royalties while avoiding early capex – minimising balance sheet stress and dilution risk. In a market that has been wary of small-cap funding rounds, that is attractive.

Timeline and next steps

Exclusivity period: 60 days, during which NMT/OMA will complete technical, legal and commercial due diligence. The period can be extended by mutual consent.
If the option is exercised, a definitive access and use licence would be negotiated and executed.
There is no certainty the option will be exercised or that binding agreements will be entered into. Ascent will update the market on material developments.

The positives and the watch-outs

What I like

Low-cost monetisation route: no upfront drilling or development costs to Ascent.
Existing wellbores: faster potential path to pilot and production than a greenfield project.
Fee stack plus royalty: immediate small cash payments, a larger permitting fee on lease grant, and upside via a revenue royalty if production happens.
Critical mineral status: possible permitting acceleration and access to US federal support mechanisms (potential, not guaranteed).

What could trip it up

No certainty: the option may expire without exercise; definitive terms are not yet agreed.
Permitting risk: the US$1.9 million permitting fee is contingent on relevant mineral leases being granted.
Operational viability: extracting lithium/potash economically from oilfield brines hinges on chemistry, flow rates, and processing – not disclosed here.
Timing risk: if commercial extraction does not commence within five years of lease grant, the royalty rate rises to 3.5%, implying a long runway may be envisaged.
Portfolio scope: permitting is pro-rated if fewer wells are available, which could reduce upfront payments.

What success could look like (without the blue-sky)

If NMT/OMA exercises the option and secures the leases, Ascent would collect the option fee and, on lease grant, the permitting fee, plus annual licence payments in arrears. In a development scenario with commercial brine production, the royalty on gross revenue becomes the main attraction. Because this uses existing wellbores, the time-to-first-cash could be shorter than a greenfield brine project, but the RNS does not provide timelines or flow expectations.

Crucially, Ascent keeps equity dilution to a minimum at this stage. For a small-cap, that is strategically valuable while they test the economic viability with experienced partners.

Jargon buster

Option agreement: a time-limited right to negotiate and enter a definitive deal on agreed terms.
Exclusivity: during the option period, Ascent/AH will not negotiate a similar licence with others.
Mineral lease: a licence from the relevant authority granting rights to explore/develop minerals.
Artesian brines: naturally pressurised saline waters found at depth; here, they may contain lithium/potash.
Royalty on gross revenue: a percentage of total sales before costs; paid if production occurs.
Payable in arrears: the fee is paid after the period it relates to, not upfront.

My take: quietly positive, with clear milestones to watch

This is a smart, low-capital option that could unlock value from Ascent’s Paradox Basin portfolio. The fee structure brings potential near-term cash on lease grant and a royalty lever for longer-term upside, all while avoiding early spend. The partnership with a lithium-focused developer and a local operator strengthens execution credentials.

Balanced against that, it is still an option with no certainty. Investors should watch for: completion of due diligence, any extension to the 60-day window, exercise of the option, grant of mineral leases (triggering the US$1.9 million permitting fee), and clarity on development plans. On today’s information, I’d mark this as strategically positive with a measured risk profile – and a decent example of monetising existing assets in a capital-efficient way.
