Solution Mining

Agapito Associates, Inc. (AAI) offers integrated capabilities in design and permitting solution mine plans for recovery of soluble minerals such as potash, trona, nahcolite and salt.

AAI has over 20 years of experience in developing solution mine plans, pilot testing, and permit support. Projects have ranged from full feasibility studies to due diligence for exploration targets. Specific areas of expertise include:

  • Resource evaluation including authoring 43-101 and JORC compliant Technical Reports (click here for a listing of recent 43-101 and JORC submittals)
  • Designing and implementing exploration and confirmation drilling programs
  • Permitting
  • Design of commercial production wells and multi-well pad design
  • Implementation of rock mechanics testing programs
  • Evaluation of cavern sizes and shape
  • Cavern layouts including evaluation of pillar sizes to control cavern closure and surface subsidence
  • Development of capital and operating costs for large solution mine plans

AAI has provided solution mining expertise worldwide. AAI’s solution mining services include task-specific technical support, feasibility assessment, and complete solution mining project management.
