The All Ordinaries Index (ASX: XAO) plays host to hundreds of mineral exploration companies.
And these highly speculative businesses have one clear mission: to unearth new mineral deposits and bring them to production.
But in the world of junior miners, few ever strike it big.
For those that do, however, the payoff can be spectacular.
And one small-cap mining stock that could be on a transformation path from explorer to producer is Meteoric Resources NL (ASX: MEI).
The company recently revealed a promising economic evaluation for its Caldeira rare earths project in Brazil.
It then backed it up with a heavily supported $42.5 million capital raise to help move the project closer to production.
In turn, this momentum has caught the eye of renowned investment house Macquarie Group Ltd (ASX: MQG), which sees serious upside potential for Meteoric's share price.
World-class rare earths deposit
Meteoric believes that Caldeira is one of the most important undeveloped rare earth deposits globally.
Located in Brazil's infrastructure-rich state of Minas Gerais, the project could represent the largest ionic clay-hosted rare earth resource in the world.
A recently concluded Pre-Feasibility Study (PFS) gauging the merits of bringing Caldeira to production also paints a pretty picture.
It forecasts an initial mine life of 20 years, with future expansion potential through exploration drilling.
And when in production, Caldeira's output could account for 8% of the world's annual rare earth oxide (REO) market, alongside 7% of the global NdPr market.
What on earth are you talking about?
Rare earths are a group of elements that play a key role in the new age world.
Their applications cover a host of modern-day industries, including renewable energy, electric vehicles (EVs), and electronics such as laptops and smartphones.
And neodymium (Nd) and praseodymium (Pr) – commonly referred to as NdPr – are the shining lights.
These two elements take centre stage in permanent magnets, which are used in EVs, wind turbines, e-bikes, and consumer electronics.
So what does Macquarie say?
Macquarie believes that Meteoric's recent capital raise marks a pivotal step in the company's life cycle.
The cash injection enables the development of a pilot production plant at Caldeira, and provides the capital to move the project towards a final investment decision (FID).
The pilot plant is expected to shed more light on ionic-type rare earth production and recovery performance, which Macquarie sees as a key focal point for the project.
The funding will also allow Meteoric to sharpen the project's economics through a more rigorous Definitive Feasibility Study (DFS).
Once that is concluded, the board of directors will have a key decision to make – to build or not to build a mine. This marks the FID.
Separately, Macquarie is also encouraged by results from the PFS, which highlighted a 40% increase in total REO output over the estimated mine life.
It describes Caldeira as an attractive project underpinned by a high-grade clay resource.
In turn, the broker has placed an outperform rating on Meteoric, with a target share price of $0.34 apiece.
This represents a stunning 106% premium on Thursday's closing price of $0.165 per share.
Risks galore
Despite the strong outlook, investors should also be mindful of the risks.
Meteoric still has a long road to travel prior to mining and cash flow.
And that's assuming it gets there.
As things stand, the group is targeting production at Caldeira in 2028.
But that depends on successful pilot plant results, a positive DFS, a host of government approvals, raising capital to build the mine, and other hurdles that need overcoming.
Such risks are real and could derail any plans for bringing the project to life.
As with most exploration companies, the upside is mighty, but so are the risks.
