Key highlights

Alvo Minerals Ltd (ASX:ALV) shares touched a 52-week high during the 19 October 2026 session and closed at $0.097, up 12.79%.
A 16 October 2026 announcement says maiden auger drilling has started at the Florence prospect of the Bluebush heavy rare earth project in Brazil.
Samples from 188 auger holes (1,369 samples) are at the laboratory, with first results expected from late October 2026.

Alvo Minerals Ltd (ASX:ALV) is an ASX-listed explorer with the Bluebush ionic adsorption clay (IAC) heavy rare earth project in Goiás and Tocantins, Brazil, the Palma copper-zinc project and the Ipora rare earth project. The shares reached a 52-week high at one point in the 19 October 2026 session, finishing at $0.097, up 12.79%. In an ASX announcement dated 16 October 2026, Alvo said maiden drilling had commenced at the Florence prospect and that 188 auger holes were awaiting assay.

Florence drilling program

Florence covers about 656 hectares in the southern part of the Bluebush tenure, south of the Praia and Boa Vista prospects. It lies entirely on the Serra Dourada granite and has not previously been drilled. More than 100 auger holes, using truck-mounted and handheld rigs, are planned to test the extent, thickness and grade of the ionic clay profile. Drilling is expected to continue through 2026 and into 2027 if results indicate prospectivity.

The announcement says the Serra Dourada granite also hosts the Serra Verde ionic clay mine, which USA Rare Earth agreed in April 2026 to acquire for about US$2.8 billion, with the transaction closing in early September 2026. Alvo states that it and USA Rare Earth together control about 95% of the granite.

Earlier results and laboratory samples

Earlier results at Boa Vista included 19.5 metres at 1,324 ppm total rare earth oxide (TREO), with 38 ppm dysprosium and terbium, from 0.5 metres in BLD004, and 6 metres at 2,537 ppm TREO from surface in BLG0008, including 3 metres at 3,415 ppm. Six batches totalling 1,369 samples from 188 auger holes at Boa Vista and São Bento are with SGS Geosol, with first results expected from late October and the rest reporting progressively into the new year.

The analysis includes full rare earth suite assays and desorption (leach) assays, which measure the extractable ionic portion of the rare earths and are a key input to a planned resource estimate and to assessing processing routes, including in situ recovery.

Geophysics and testwork

Alvo’s portable time-domain electromagnetic system, Loupe, completed more than 18 kilometres of lines at Boa Vista in early October and is due to start at Florence within about 10 days, to map the depth to fresh granite. The announcement says Bluebush covers 9,859 hectares, that diamond holes intersected fresh granite between 10 and 35 metres below surface, and that earlier first-pass desorption testwork extracted up to 83% of total magnet rare earths (average 56%). Samples are also with ANSTO for diagnostic and column leach testwork, and permeability has not yet been measured.

Sector backdrop

The benchmark index finished the 19 October 2026 session higher. The S&P/ASX 200 (ASX: XJO) stood at 8,845.70 at 4:25 pm (GMT+11) on 19 October 2026, up 0.44%, or 39.00 points, for the day. The sector map does not carry a separate label for Mining or rare earths, so the figures below describe the broader market. More broadly, Energy rose 2.16%, Industrials 0.93%, Financials 0.85%, Utilities 0.38% and Consumer Staples 0.25%, while Information Technology fell 1.35%, A-REIT 0.34%, Consumer Discretionary 0.18%, Telecommunication Services 0.16% and Health Care 0.13%; one unlabelled segment rose 0.11%.

The Alvo announcement is dated 16 October 2026, the last trading day before the 19 October session, and it does not discuss share price movements.

Risks shareholders should weigh

The Florence prospect has not previously been drilled, and auger drilling tests only the near-surface clay profile. Results from the laboratory are pending, and the announcement says leach results will show how much of the dysprosium and terbium is held in an extractable ionic form, which is not yet known for the new samples. Handheld XRF readings are qualitative.

Alvo has not yet measured permeability at Bluebush, so suitability for in situ recovery has not been established. A maiden JORC resource estimate has not been completed and is targeted for early 2027. Comparisons with the neighbouring Serra Verde operation relate to host rock only and do not indicate similar results. Funding for continued drilling is not described in the announcement.

What’s next

The listed next steps are completing the Florence auger program and electromagnetic survey followed by soil sampling, reporting assay results as received, continuing infill auger drilling at Boa Vista, finishing the ANSTO testwork and delivering a maiden JORC resource estimate for Boa Vista, targeted for early 2027.
