Gypsum appears greyish, with a hardness of about 2.0 and a specific gravity of 2.2. Gypsite deposits are formed by the solution of existing gypsum deposits by groundwater, which then evaporates at the surface, leaving a porous aggregate of gypsum. The degree of hydration plays a crucial role in evaluating the economic potential of a gypsum deposit. FOUR J Gypsum contains 32.6% CaO (calcium oxide), 46.5% SO3 (sulfur trioxide), and 20.9% H2O (water).
Calcium Sulfate Dihydrate (CaSO4 2H2O) 88%
FOUR J Gypsum is naturally sourced. Its high quality, combined with the numerous benefits gypsum offers, makes it an excellent choice for enhancing soil structure, improving water infiltration, and providing essential nutrients to plants and soil microbes. By incorporating FOUR J Gypsum into your farming practices, you can create the optimal conditions for robust plant growth and cultivate a healthy, sustainable ecosystem.
The FOUR J gypsum mining project will involve extracting accessible historic gypsum material. An Environmental Management Plan (EMP) has been developed to provide guidance to all personnel, contractors, and third-party service providers involved in the onsite gypsum extraction works, to ensure that safe, compliant, environmentally, and
socially responsible actions are taken to mitigate potential project effects on the environment. This EMP is designed to comply with legislative requirements, conditions of the environmental approvals and guidelines. It identifies and outlines:
Site and activity‐specific environmental management and monitoring plans designed to
protect the human and ecological environment)
Key construction and operations activities, applicable environmental mitigation measures,
and best management practices (BMPs), and
Environmental monitoring, reporting, and regulatory compliance requirements.
Project personnel will be required to comply with the EMP or provide a suitable alternative
approach that can be incorporated into an updated EMP, if necessary.
Reclamation will consist of areas being decompacted and recontoured to match original conditions. Existing soil stockpiles onsite will be utilized to promote seeding and vegetation growth. As such, with the exception of follow up to assure that reclamation has been successful.
This Reclamation Plan has been developed based upon the AME Reclamation Guide for Mineral Exploration (August 5, 2020) and the Ministry of Energy, Mines and Low Carbon Innovation Health, Safety and Reclamation Code of Mines in British Columbia, Section 10.7 (Revised November 2022).
