Global Lithium Secures MDCP Approval for Manna Lithium Project

Global Lithium Clears Critical Permitting Milestone at Manna Lithium Project

Global Lithium Resources (ASX: GL1) has received approval for the Mining Development and Closure Proposal (MDCP) for its Manna Lithium Project in Western Australia, marking an important regulatory step as the company works toward a targeted Final Investment Decision (FID) in Q4 2026, first direct shipping ore (DSO) in Q2 2027, and first SC5.5 spodumene concentrate production in mid-2027.

According to the ASX announcement dated 4 August 2026, the approval was granted by the Department of Mines, Petroleum and Exploration and was received slightly ahead of the company's internal timeline. For investors following lithium project development in Australia, that matters because permitting milestones often shape whether development schedules remain on track.

"This is a testament to the dedication and expertise of our team and strengthens our integrated Manna-Nova development plan. Securing this critical permit further accelerates our path to production, underpinning our commitment to become Australia's next lithium producer and delivering real value to our shareholders and community partners," said Dr Dianmin Chen, Managing Director of Global Lithium Resources.

What the MDCP Approval Means for Manna

In the announcement, Global Lithium described the MDCP approval as a "significant regulatory milestone" that further reduces development risk for the Manna Project. In practical terms, the approval allows the company to move ahead with important early works and critical mine-site infrastructure.

The approved MDCP covers the main physical footprint of the proposed mine and associated support infrastructure. This includes:

• Three open pits, comprising Manna Main, Manna North and Manna South
• Waste rock storage areas
• Dry stack tailings facilities
• Ore stockpiles
• Accommodation village
• Bore field
• Topsoil stockpile areas
• Associated mining infrastructure

This is a material step because the MDCP is one of the key approvals needed before substantial site development can proceed. Without it, major early-stage construction activity at the mine site would typically remain constrained.

Furthermore, for GL1, the permitting outcome directly supports the company's plan to fast-track development at Manna and aligns with its broader integrated Manna-Nova strategy.

Understanding the MDCP: An Educational Guide for Investors

For many retail investors, mining approvals can appear administrative. In reality, however, they can have direct implications for project timing, capital planning and overall execution risk.

What Is a Mining Development and Closure Proposal?

A Mining Development and Closure Proposal is a formal document required in Western Australia that sets out how a mine is expected to be developed, operated and ultimately rehabilitated after mining ends. In simple terms, it shows regulators what the mine will look like, how it will function, and how the site is expected to be managed over its full life.

It generally includes:

• The proposed mine layout
• Pit designs and infrastructure locations
• Waste and tailings management plans
• Surface disturbance areas
• Closure and rehabilitation measures

Why Does MDCP Approval Matter to Investors?

From an investment perspective, an MDCP approval can be viewed as a project de-risking event. It does not guarantee production or commercial success, but it does remove an important regulatory hurdle from the development pathway.

That matters for several reasons:

1. It improves schedule confidence — If a project receives key approvals on time, management's published development targets may carry greater credibility.
2. It supports financing and board decisions — A company is generally better placed to advance toward an FID when core permits are in place.
3. It narrows regulatory uncertainty — Permitting delays can affect construction sequencing, capital timing and market confidence.

For GL1, the company has linked the MDCP approval directly to the next stage of development and to the planned Q4 2026 FID.

Manna Lithium Project Resource and Reserve Base

The Manna Lithium Project is Global Lithium's primary development asset, located 110 kilometres east of Kalgoorlie-Boulder on Kakarra Country in Western Australia. According to the announcement, the project is planned to operate for at least 14 years.

The project's scale is supported by both a defined Mineral Resource and an Ore Reserve, which are separate but related concepts for investors to understand.

Manna Mineral Resource

Global Lithium reported a total Indicated and Inferred Mineral Resource for Manna of 51.6 million tonnes at 1.0% Li₂O.

A Mineral Resource is an estimate of the amount of mineralisation in the ground. It does not automatically mean all of that material can be mined economically, but it indicates the size and quality of the deposit based on available drilling and geological data.

Manna Ore Reserve

The company also reported a Grand Total Ore Reserve for Manna of 19.4 million tonnes at 0.907% Li₂O.

An Ore Reserve is the portion of a Mineral Resource considered mineable after applying factors such as mining method, processing assumptions, economics and permitting. For investors, an Ore Reserve generally carries more direct relevance to production planning than a broader Mineral Resource.

The company's wider portfolio also includes the Marble Bar Lithium Project, although the announcement noted that this asset is subject to a proposed divestment announced on 22 April 2026. That indicates GL1's primary operational focus remains on Manna.

Development Timeline and Upcoming Catalysts

The MDCP approval feeds into a clearly defined series of targets outlined in the ASX update. For investors, the timeline provides a practical framework for tracking execution over the next 12 months.

The sequence is important. The company has indicated that MDCP approval will help inform the Final Investment Decision, which is the formal point at which the company decides whether to commit to the next stage of project execution.

How Is Production Staged?

The production pathway is also staged. GL1 is targeting DSO first, followed by SC5.5 spodumene concentrate. That suggests an approach where raw ore shipments may precede the ramp-up of concentrate production.

For investors less familiar with lithium mining, direct shipping ore refers to ore that can be mined and sold with limited processing, while spodumene concentrate is a more refined lithium-bearing product produced through processing. Concentrate is typically the more established product in the hard-rock lithium supply chain.

The Manna-Nova Development Plan in Context

A central part of the company's language around the approval is the integrated Manna-Nova strategy. The announcement did not provide detailed technical or commercial specifics on Nova within this release, but it did state that the MDCP approval directly supports early works and critical infrastructure tied to this integrated development plan.

From an investor standpoint, that means the mine-site approval at Manna is not being presented as an isolated event. It is being framed as part of a broader operating model that links mining activity at Manna with downstream project infrastructure.

That point matters because project integration can affect:

• Capital allocation
• Development sequencing
• Operating efficiency assumptions
• Execution complexity

At this stage, the ASX announcement supports the view that Manna remains the key mine development component within GL1's broader plan.

Why This ASX Announcement Matters for the Investment Case

This approval is material because it changes the quality of the development story. Global Lithium is no longer being assessed only on exploration scale or resource size. It is now being assessed on whether it can convert a defined lithium deposit into an operating mine within the timetable set out by management.

1. Regulatory Progress Is Tracking to Schedule

The company stated that the MDCP approval was granted on schedule and slightly ahead of internal timelines. In the mining sector, permitting delays are common, so on-time progress can be a useful indicator of development discipline.

2. Manna Has Both Scale and Mine Life

A 51.6Mt Mineral Resource, 19.4Mt Ore Reserve, and a planned mine life of at least 14 years provide a substantial base for project development. These figures suggest Manna is not a short-duration or early-stage concept asset.

3. FID Is Moving Closer

The company has tied this approval to a targeted Q4 2026 Final Investment Decision. That makes the next few months particularly relevant, as investors will likely look for updates on engineering, funding, construction planning and any additional approvals that may feed into that board-level decision.

4. Production Targets Are Now Relatively Near Term

According to the announced schedule, GL1 is aiming for first DSO in Q2 2027 and first concentrate in mid-2027. While these remain forward-looking targets rather than guaranteed outcomes, they place the project within a shorter development horizon than many listed lithium peers.

Key Terms Investors Should Understand

A mining development announcement often contains terminology that can obscure the practical meaning of the update. These are the main terms relevant to GL1's release.

• MDCP — A regulatory document in Western Australia that outlines how a mine will be built, operated and closed.
• FID (Final Investment Decision) — The formal company decision to commit capital to project development.
• DSO (Direct Shipping Ore) — Ore that may be sold with limited processing.
• SC5.5 spodumene concentrate — A processed lithium product containing around 5.5% Li₂O, used in the hard-rock lithium supply chain.
• Li₂O — Lithium oxide, the standard way lithium grade is reported in hard-rock deposits.
• Indicated Resource — A resource category with a higher level of geological confidence than Inferred.
• Inferred Resource — A lower-confidence resource category based on more limited geological evidence.
• Ore Reserve — The mineable portion of a resource after technical and economic factors are considered.

Why Investors May Keep GL1 on Watch

Global Lithium's latest ASX update places attention firmly on execution. The resource base is in place, the ore reserve is defined, the mine life has been outlined, and a key development approval has now been secured.

What comes next is likely to matter more than the approval itself. Investors will be watching whether GL1 can convert this regulatory progress into further site activity, maintain momentum toward the Q4 2026 FID, and then move toward the company's stated production targets in 2027.

In addition, the broader context of lithium demand and supply chain development in Australia adds further relevance to milestones like this one. For now, the MDCP approval provides a clearer development pathway for the Manna Lithium Project and gives the market a concrete milestone against which future delivery can be measured.
