:: Bacanora Announces Completion of Pilot Plant Construction and Commencement of Commissioning


Bacanora Minerals Ltd. is pleased to announce that construction of its pilot plant in Hermosillo, Mexico is complete and it is entering the commissioning phase. Commissioning is expected to take approximately two weeks. The pilot plant will initially be supplied with colemanite-bearing material excavated from the Company's El Cajon borate deposit located near the town of Magdalena de Kino, Sonora, Mexico. Bulk sampling of approximately 2,000 tonnes of material from the El Cajon borate deposit has been completed to use as feed for the pilot plant.

The pilot plant has the capacity to process 150 tonnes of material per day. The object of the test work will be to produce colemanite samples for potential consumers, in order to establish a market and pricing for El Cajon colemanite, as well as data needed to move the project forward to the feasibility stage for larger borate mining and production facilities.

In addition, at the pilot plant laboratory, bench tests on low-grade (6% to 10% B2O3) colemanite-bearing material have successfully recovered boric acid. The low-grade material used for these tests is not in the current mineral resource inventory. Addition of a boric acid circuit to the pilot plant is underway as boric acid is a higher margin product than colemanite and production of boric acid from lower grade material would considerably extend the life of mine.
