Appia Announces Drilling Updates on ULTRA HARD ROCK Target and Auger Drilling on ULTRA IAC Target in Goias, Brazil
MWN-AI** Summary
**Appia Rare Earths & Uranium Corp. Provides Key Drilling Updates in Goiás, Brazil**
On December 9, 2025, Appia Rare Earths & Uranium Corp. (CSE: API; OTCQB: APAAF) announced significant advancements in their drilling initiatives at the ULTRA HARD ROCK and ULTRA IAC targets in Goiás, Brazil. Following Ultra Rare Earth Inc.'s acquisition of a 50% interest in the previously named PCH Project on October 31, 2025, they are now the project operator. The High-Grade Zone is now referred to as the ULTRA HARD ROCK carbonatite target.
Appia reports that a 7,000-meter diamond drilling campaign is currently underway, utilizing three rigs. Thus far, seven drillholes have successfully intercepted carbonatitic breccia, affirming the intrusion's extensive reach at surface and down to 300 meters. Notable historical drill results from the 2024 campaign indicated impressive rare earth oxide grades with intercepts, enhancing confidence in the current drilling program.
In addition to the diamond drilling, auger drilling at the ULTRA IAC target has progressed, with 244 auger holes completed. Preliminary results from the Gaia sector indicate promising grades comparable to those from the Merope and Taygeta sectors.
Tom Drivas, CEO of Appia, expressed enthusiasm over the early results from the ongoing drilling, which closely resemble previous findings, prompting an expansion of the drilling program to encompass 26 additional holes by mid-January 2026. Assay results for these new drillholes, which focus on delineating the carbonatitic intrusion's dimensions, are pending and expected later this year.
As Appia continues to explore its Brazilian properties, it remains committed to advancing its presence in the rare earths and uranium sectors, with a strategic interest in high-grade deposits across multiple locations. The company currently holds 194.4 million shares outstanding.
MWN-AI** Analysis
Appia Rare Earths & Uranium Corp. (CSE: API) appears to be making significant strides in its exploration efforts in Goias, Brazil, particularly with its ULTRA HARD ROCK and ULTRA IAC targets. The company’s recent announcement of ongoing diamond and auger drilling activities aligns with a broader trend in the rare earths sector, where demand continues to soar due to the proliferation of electric vehicles and renewable energy technologies.
The drilling updates are promising, particularly with the ongoing 7,000-meter diamond drill campaign at the ULTRA HARD ROCK target, which has already produced several intercepts of carbonatite. Notably, previous drill results indicate significant grades of Total Rare Earth Oxides (TREO) and Niobium (Nb2O5)—metrics that could position Appia favorably against its peers. The continuous drilling at depth, which remains open in multiple directions, suggests the potential for significant resource expansion and grade continuity.
Similarly, the auger drilling at the ULTRA IAC target is showing encouraging signs of potential, with results from the Gaia sector mirroring the quality found in previous drilling areas. As results from both the diamond and auger drilling campaigns are pending, investors should monitor these closely; positive assay results could trigger substantial upward momentum in Appia's stock.
Given the company's substantial land portfolio in Brazil and its interests in high-grade rare earths and uranium, it remains well-positioned in a rapidly evolving market. Investors should consider the inherent risks in exploration stages, as outcomes can be unpredictable. However, for those with a higher risk tolerance, Appia's current operational momentum makes it a compelling watch as the landscape for rare earth metals becomes increasingly pivotal for global economies. Cautious investors may want to await assay results before making significant commitments.

Toronto, Ontario--(Newsfile Corp. - December 9, 2025) - Appia Rare Earths & Uranium Corp. (CSE: API) (OTCQB: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0) (the "Company" or "Appia") is pleased to announce that Ultra Rare Earth Inc. ("Ultra") is continuing with the diamond drill program, announced by Appia in its press release dated October 22, 2025, on the High Grade Zone on the project formerly known as the PCH Project. Ultra acquired a 50% interest in the PCH Project on October 31, 2025 (see Press Release dated November 3, 2025). Ultra is now the Operator of the PCH project. The High-Grade Zone has been renamed the ULTRA HARD ROCK carbonatite Target. The diamond drilling program under the supervision of Ultra continues to intercept carbonatitic breccia from surface to the end of hole. Ultra is continuing with the auger drilling commenced by Appia in August on the Taygeta, Merope and Gaia targets, which have been renamed the ULTRA IAC target and comprise the Taygeta, Merope and Gaia sectors respectively, confirming expansion in the area of the Ionic Adsorption Clay (IAC) Rare Earth Elements (REE). Appia holds a 25% interest in the ULTRA Hardrock and ULTRA IAC Projects, which is 42,932.24 ha. in size and located within the state of Goiás in Brazil.
Highlights
- ULTRA HARD ROCK - 7,000 metres drilling campaign underway with three diamond drill rigs.
- ULTRA HARD ROCK - 7 new drillholes already completed (1,513.5 metres) intercepting the carbonatite on all their extensions.
- ULTRA HARD ROCK - Carbonatite intrusion remains open in all directions.
- ULTRA HARD ROCK - The drillholes of this campaign are an extension of the three drillholes PCH-DDH-002, PCH-DDH-003, PCH-DDH-004 executed in 2024 that intercepted 150m @ 1.34% TREO, 0.13% Nb2O5 from surface; 147m @ 2.00% TREO, 0.23% Nb2O5 from surface; 153m @ 1.32% TREO, 0.20% Nb2O5 from surface respectively (see Press Release dated March 10th 2025).
- ULTRA HARD ROCK - Carbonatite was intercepted at 300 metres true vertical depth and remains open at depth.
- ULTRA IAC - 244 auger drillholes completed.
Tom Drivas, CEO & Director of Appia, commented: "The drill core results from the first three diamond drill holes of the October 2025 drill program were visually very similar to the results from the 2024 drill campaign; prompting Ultra to mobilize two additional drill rigs to site to expedite the drilling of an additional 20 holes (6,000 m) to complete the expanded drilling program by mid-to-January 2026."
The new drillholes are planned to reach up to 300 metres with the main goal being to delineate the dimensions of the carbonatitic intrusion and confirm the continuity of the grades already identified in the previous program. All the new drillholes on the ULTRA Hard rock carbonatite Target intercepted only carbonatitic breccial similar to the ones already tested (Figure 1). Assay results are pending, and initial results are expected by the end of the year.

Auger drilling on the IAC zones is progressing well with results on the Gaia sector showing similar grades and desorption characteristics to those found on the Merope and Taygeta sectors (Table 1). The auger drilling is now expanding the Taygeta sector and will be followed by auger drilling on the Merope sector (Figure 2). Assay results from the latest auger drilling on the Taygeta sector are pending.
