Largo Inc., the vanadium powerhouse, just delivered a Q1 2024 earnings call brimming with intriguing tidbits. While analysts focused on the immediate challenges of depressed vanadium prices and operational hurdles, a tantalizing detail seems to have slipped under the radar. Largo might be sitting on a platinum-laden treasure trove, one that could dramatically reshape their future, and investors might be entirely oblivious.

Here's the story. Largo's Maracás Menchen Mine in Brazil, the source of their impressive vanadium production, has always been a geological marvel. But recent exploration efforts surrounding the mine's Campo pit have unveiled an unexpected twist. Alongside vanadium, the exploration program unearthed significant Platinum Group Metals (PGMs) grades in the non-magnetic tailings ponds. This discovery has far-reaching implications, potentially transforming Largo from a vanadium specialist into a multi-metal powerhouse.

Historically, PGMs at the Maracás Menchen Mine were thought to be primarily associated with massive vanadium ore. This new finding turns that assumption on its head, suggesting a stronger correlation with non-magnetic material. Think about it: if PGMs are concentrated in this readily accessible tailings material, Largo could unlock a new revenue stream without dramatically altering their existing operations.

The potential scale of this platinum windfall is still shrouded in mystery. Largo is understandably tight-lipped, promising further studies to evaluate the viability of PGM recovery as a byproduct of their vanadium and ilmenite operations. But let's indulge in some educated speculation.

Largo's 2024 ilmenite production guidance stands at a robust 88,000 tonnes. Assuming even a conservative 0.1 grams per tonne of PGM concentration in the non-magnetic tailings (a figure often seen in PGM-rich deposits), Largo could potentially extract around 8.8 kilograms of PGMs annually. With platinum currently trading around $1000 per ounce, that translates to a potential additional revenue stream of roughly $300,000 per year – a seemingly modest sum until you consider the low-cost nature of tailings reprocessing.

The real game-changer, however, lies in the possibility of higher PGM grades. If the concentration reaches 0.5 grams per tonne (achievable in some PGM-rich deposits), the potential annual revenue from platinum skyrockets to $1.5 million. This figure becomes even more enticing when considering the scalability of tailings reprocessing. Largo could ramp up PGM extraction significantly without major capital expenditure, effectively piggybacking on their existing infrastructure.

Potential Platinum Revenue from Tailings Reprocessing

Of course, this is just the tip of the iceberg. Further studies are crucial to determine the true extent and economic viability of PGM recovery. But the signs are undeniably promising. Largo's exploration program could unlock a platinum-plated secret, one that could significantly bolster their financial performance and redefine their position in the metals market. Investors might be wise to keep a close eye on these developments, as Largo's journey down the platinum rabbit hole could be a ride worth taking.

Largo's V2O5 Production and Global Recoveries

Despite the focus on platinum, Largo's core vanadium business faces challenges. The following chart, based on data from the Q1 2024 earnings call, illustrates the recent decline in V2O5 production and global recoveries. This decline, largely attributed to lower ore grades and extended maintenance periods, underscores the need for Largo's operational improvement plans.

While the world is captivated by the rise of vanadium flow batteries and the clean energy revolution, Largo might just be playing a multi-dimensional chess game. They are not only a key player in the energy transition, but also potentially a custodian of a hidden platinum treasure. This vanadium enigma might just be the platinum-lined surprise that savvy investors have been waiting for.
