Planning and organising effective site visits

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.  It is therefore essential that site visits be well planned and organised to maximise their value. Derisk consultants have undertaken many site inspections and share their tips to ensure your next site visit is well-organised and effective.

How important is a Pre-feasibility Study?

The typical study sequence for mineral projects envisages three or four significant study levels as a project progresses from exploration through to production.  Each of these studies occurs at a different point in the life of a project and each serves a different purpose, although all are intended to underpin a commercial decision regarding the future of the project. In some cases, companies try to fast track their projects by skipping the PFS stage.

Valuing operations with minimal Ore Reserves

Many mining projects have limited Ore Reserves defined at any time, however many of these projects have a long operating life. Most of these projects have sufficient additional Mineral Resources or Production Targets to support a few more years of production. In some parts of the world, it is normal to start and operate projects with little or no Ore Reserves and often without the benefit of a formal feasibility study. Whilst these situations may not be a problem for the operating companies, they can be a major headache for consultants engaged to provide an independent valuation.

Future of site-based mining geologists

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?

Due diligence: How long is a piece of string?

Companies considering an option to purchase a mineral asset generally embark on some form of technical due diligence, review or audit to assess the asset and inform management of the key technical and financial risks and opportunities associated with the asset.   Derisk works with clients to carefully understand what they require from their due diligence to enable an appropriate scope of work to be assembled.

The value and importance of geological database integrity

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.

Who reads your Ore Reserve statement and why?

Ore Reserve is a critically important term used throughout the minerals industry. Defined in the JORC Code as “the economically mineable part of a Measured and/or Indicated Mineral Resource”, it includes an estimate of tonnes and grade (or quality) at a project or operating mine. But this important set of numbers is much more than this, and means very different things to different stakeholders.

Mining: High risk or high reward

Mining is often regarded as a “high risk” industry, also capable of delivering “high rewards” when times are good. Derisk Geomining Consultants, as the name implies, is focused on providing services that minimise technical risk and maximise the value of your most valuable asset – your mineral deposit.

Public vs. private mining companies: Some pro's and con's from a techncial perspective

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?

What is safety and how is it achieved

Derisk Geomining Consultants principal 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.

Will innovation make existing drilling, geological logging and sampling methods redundant

Derisk Geomining Consultants director and principal geologist Mark Berry recently gave a thought-provoking presentation titled ‘Will innovation make existing drilling, geological logging and sampling methods redundant?’ to the Australian Drilling Industry Association (ADIA) 2017 conference.
