Arianne Phosphate Partnership Produces Marketable Calcium Carbonate

Arianne Phosphate Inc. (DAN) has successfully produced marketable precipitated calcium carbonate (PCC) as a co-product during purified phosphoric acid (PPA) production at its Lac à Paul project, operating in joint venture with Travertine Technologies. The PCC was qualified by a Canadian building materials end-user for use in formulations including cement, concrete, and asphalt shingles. This development creates an additional revenue stream while permanently storing carbon dioxide, thereby reducing the environmental footprint of building materials.

Testing of the PPA continues, with samples meeting specifications for a Western LFP battery cathode active material (CAM) producer. Additional samples have been sent to industrial chemical and fertilizer producers, with results pending. The joint venture process reduces sulphuric acid requirements, lowers operating expenses, and eliminates traditional phosphogypsum waste.

In an administrative update, CEO Jeffrey Beck was granted 200,000 stock options at $0.285/share, expiring October 22, 2036, in lieu of salary and cash remuneration.

Arianne Phosphate Inc. (DAN) released an update on October 22, 2026, following its October 8, 2026 announcement regarding LFP battery specifications and the June 2026 pilot-scale PPA success. The release qualifies the PCC co-product, validating the Travertine JV's ability to monetize a traditional waste stream, which improves project economics and the ESG profile.

The news is incremental and expected given the JV framework and pilot results. It does not represent a new contract, financing, or material change to the company's financial position. Additionally, the CEO option grant is a standard compensation mechanism and does not impact operational or financial metrics. Overall, the release confirms execution progress on the downstream strategy but lacks the novelty or scale to be classified as material or game-changing.

Arianne Phosphate Inc. (DAN) is developing the Lac à Paul project in Quebec, Canada, which hosts the world's largest greenfield phosphate deposit. The site features an igneous ore body that yields high-purity, low-contaminant concentrate grading up to 41.5% P₂O₅. It is described as the West's only permitted greenfield phosphate mine.

The company is transitioning from a pure miner to a downstream producer of purified phosphoric acid (PPA) for LFP batteries, food additives, pharmaceuticals, and semiconductors. A prefeasibility study (PFS) supports the project, with a mine life of over 25 years at 3M tonnes/year throughput.
