American Pacific nearing high purity Boric Acid production

By Justin Ware. Published at Apr 12, 2019, in Mining

American Pacific Borate & Lithium (ASX:ABR) has delivered a high 99%+ pure boric acid crystal with minimal impurities from its process optimisation works.

The process optimisation works were completed on April 10, which were designed to ensure the consistent delivery of a technical grade quality product from the company’s Fort Cady Borate Project.

ABR’s CEO Michael Schlumpberger commented on the results, “This is another hurdle completed in our aspiration to commence production of borates from our flagship Fort Cady Borate Project and ultimately to become a globally significant producer of high purity borate products.”

Process Optimisation Works

Since the completion of the Definitive Feasibility Study at Fort Cady, ABR has turned its attention to ensuring it can consistently deliver a technical grade premium boric acid product.

The results of these works have been very encouraging to date, with a final process now designed to ensure the highest grade product with minimal impurities will be delivered consistently by the project site.

The process includes:

  1. Treating liquor (Pregnant Leach Solution or PLS) that was retrieved on site from the Fort Cady orebody by solvent extraction, using isoctanol as the organic extractor.
  2. Further treating the resulting liquor in a scrubbing stage (sulfuric acid and ion-exchange) to purify liquor, and
  3. Crystallising the final liquor via a crystalliser manufacturer where the liquor was sent for evaluation and testing of the crystallisation steps of the process (as seen below).

“Our focus now turns to the completion of detailed engineering and securing the modest financing for the low capital starter project," Schlumpberger added.

“Importantly, we have delivered a very low capital starter project with brilliant financial metrics that sees us on a pathway to becoming a globally significant producer of borates targeting an EBTDA of over US$340 million per annum.

“When you consider borates are a vital input into new world technologies including electric vehicles, clean energy and food security related micro nutrients for optimal plant growth, we are sure demand for borates will only continue to grow.”

ABR commences funding stage

The company has now begun an informal process to secure funding for Phase 1A of the Fort Cade Borate Project. This process has tested lender appetite to significantly debt finance the initial operation, with responses to enquiries largely positive to date.

ABR is seeking to commence a formal engagement process in the current quarter, with a view to being fully financed by Q4 CY2019.
