Brazilian Rare Earths' World-Class Grade Gets Validated by a Rival Deal

Government approval, processing breakthroughs and a rival's much lower-grade $2.8 billion acquisition have all confirmed the quality of BRE's deposit.

Brazilian Rare Earths delivered one of the ASX's most explosive rare earths stories, rising as much as 60 percent on government approval for a Brazilian pilot plant and further surging on processing breakthroughs, before a rival's acquisition at a much lower grade validated its own world-class deposit, and a subsequent fall despite even higher-grade drilling results was attributed to index-related trading rather than fundamentals.

Government approval and a major discovery drive an initial surge

Pengana Capital Group said the stock rose 60 percent after announcing government approval for a rare earth pilot plant in Brazil and a major new discovery at its Sulista project, with the pilot plant approval an important indicator of government support for the project despite its uranium content, noting Brazil operates three nuclear reactors and is a net importer of uranium, which it seeks to displace with domestic supply.

Processing breakthroughs dramatically improve project economics

Pengana Capital Group said the stock rose 41 percent following two important processing breakthroughs, first that the company can more than double the grade of its ore using a simple, low-cost sorting process, increasing total rare earth oxide grades from 12.7 percent to approximately 27 percent, and second that metallurgical testing demonstrated 97 percent of contained total rare earth oxide can be extracted using a relatively low-temperature process. Perennial Partners confirmed the 41.1 percent bounce after releasing positive metallurgical test work results, suggesting capex for the processing plant would be less than previously expected.

A rival's lower-grade acquisition validates BRE's asset quality

Pengana Capital Group said the stock rose 17 percent, buoyed by positive sentiment toward the Brazilian rare earth sector after USA Rare Earth acquired Serra Verde for US$2.8 billion, noting that while Serra Verde has the key advantage of already being in production, it is significantly lower grade than Brazilian Rare Earths, with a grade of 0.15 percent compared to 14 percent for BRE, with the war in Iran also boosting fuel prices.

World-class drilling results across a vast tenement

Perennial Partners said the stock bounced 32.7 percent on a mixture of anticipation of the spin-out of its bauxite assets and index inclusion. Pengana Capital Group said the stock later fell despite announcing drilling results from its fourth major area, called Velhinhas, on its vast 1,800 square kilometre tenement, with the highest-grade intercept at 19 percent total rare earth oxide, though most intercepts were in single digits, still world-class, noting Lynas currently operates the richest rare earth deposit globally at grades of approximately 6 percent. Perennial Partners said the stock fell 32.1 percent despite announcing more very-high-grade exploration results, attributing the fall to index-related trading and generally weak commodity markets rather than fundamentals.

What fund managers say they are watching next is continued drilling success across the vast 1,800 square kilometre tenement, delivery of the low-cost sorting and extraction process breakthroughs into commercial production, progress on the bauxite asset spin-out, and whether the stock's valuation reconnects with fundamentals given index-related trading effects.
