Derisk staff have compiled a series of short technical notes covering a diverse range of topics relevant to the mineral industry. Please take a moment to browse through these notes and contact us if you would like more information.
Successful exploration programs reach a stage where there are substantial Inferred Mineral Resources.
Site visits to exploration prospects, mine development properties and operating mine sites can be a critical component of many project reviews, audits, technical studies, expert reports and operational support projects undertaken for a client.
The typical study sequence for mineral projects envisages three or four significant study levels as a project progresses from exploration to production:
Many mining projects, particularly narrow vein underground precious metals projects, have limited Ore Reserves defined at any time.
When will site-based mining geologists become redundant? And will the Coronavirus pandemic provide further incentive to fast-track a process that has already commenced?
Companies considering an option to purchase a mineral asset generally embark on some form of technical due diligence
Exploration and mining companies have only one primary asset – what’s in the ground they own or have rights over. Consequently, the geological database is the cornerstone of a company’s most important asset.
Ore Reserve is a critically important term used throughout the minerals industry.
Mining is often regarded as a “high risk” industry, also capable of delivering “high rewards” when times are good.
Mining is a global business and operated by both publicly-listed and privately-owned companies. From a technical perspective, what are the key advantages and disadvantages of each option?
Derisk principal mining consultant Mal Dorricott defines safety as an outcome that is achieved when an activity is completed or a process operates without harm to the assets involved in that activity or process.
Derisk Director and Principal Geologist, Mark Berry, recently gave a thought-provoking presentation ‘Will innovation make existing drilling, geological logging and sampling methods redundant?’ to the Australian Drilling Industry Association (ADIA) 2017 annual conference.
