Early Phase of Mineral Exploration: Developing a solid foundation

Generating potential targets for geological evaluation is the critical first stage in the mineral exploration process. Initially, review of existing geological data and other relevant source is performed, including information from depleted mines and previous exploration work. This process will provide important guidance for a more cost effective exploratory program.

Prospecting is the systematic process of searching for a mineral deposit by narrowing down areas of promising enhanced mineral potential. In other words, prospecting involves searching a district for mineral deposits with the view to mine it at a profit (Adapted from Hartman, 2002 and Fernberg, 2010).

During the stages of prospecting and exploration of a mining project, there is usually great potential for value creation. A mining project may change hands during these stages, with exploration and junior mining companies often owning projects in the initial exploration stages, and with medium and larger mining companies acquiring projects and developing them further into the post feasibility stages. Typically, exploration and junior mining companies do not generate any cash flow or earnings. These companies often consist of a management team, one to several properties and some cash. They raise risk capital by selling shares for exploring potential mineral deposits (Adapted from Hohn, 2009 and Smit, 2008).

Traditionally, prospecting was the search for simple visual surface indications of mineralization. Nowadays the range of surface indications expanded significantly by the use of sophisticated geophysical and geo-chemical techniques. However, the skills and abilities involved in successful prospecting are common to all techniques. They involve hands on approach, communication skills, knowledge, insight, opportunism, persistence, lateral thinking and luck (Adapted from Marjoribanks, 1997).

Once a prospect has been identified, and the right to explore it acquired, assessing it involves advancing through a progressive series of definable exploration stages. Positive results in any stage will lead to advance to the next stage and an escalation of the exploration effort. Negative results mean that the prospect will be discarded, sold or joint ventured to another party, or simply put on hold until the acquisition of new data, concepts and/or technology lead to a positive re-evaluation and subsequent reactivation (Adapted from Marjoribanks, 1997).

Early and sustained engagement and partnerships among governments, industry, and communities are critical at each stage of the mineral development sequence. Sustained engagement and partnership help to alleviate some of the issues and concerns that act as barriers to advancing resource projects. Relationships developed through collaboration and dialogue among multiple stakeholders, communities, and governments offer the opportunity to gain a better reciprocal understanding, establish trust, develop respect, and identify mutually beneficial goals in a transparent manner (Adapted from Advisory committee Energy and Mines Ministers’ Conference, 2014).

As identified by The National Stone, Sand and Gravel Association (NSSGA), sustainable business practices integrate environmental stewardship, social responsibility and economic prosperity to ensure the long-term supply of aggregate materials to society.  The long-term viability of the industry is dependent on obtaining and maintaining a social license to operate.

Are you aware of any mining project in your area (e.g. aggregates operations) ? Do you have any suggestion regarding sustainable initiatives?
