A working product line

Purebase began as a natural-resource company developing mineral products for agriculture and industry. As the company has focused its energy on metals, that work has continued — three agricultural products remain in production and available to growers.

Purebase's agricultural products are natural mineral soil amendments and a mineral plant protectant, developed for commercial farming operations and drawn from the company's own mineral deposits.

They are supplied for use on organic and non-organic crops, including citrus, nut trees and row crops, and are sold to growers directly and through distribution.

These products sit alongside the metals business rather than in place of it. The metals operation remains the company's principal focus and the basis of its investment case; the agricultural line continues to serve the customers it was built for.
