Objective

To help improve contemporary exploration strategies via economic evaluation of junior exploration companies.

(Sirius Resources CET 2014 Presentation)

Wider Scale Importance

• The current crisis
• No systematic analysis for investment
• Form a new model to evaluate exploration strategy
• Recognising strategies to increase the effectiveness of exploration

investment.

(Koch et al., 2015)

The Fraser Range:

Prospective for Nickel-Copper

(Smithies et al. 2013)

• 1. To document the strategies of nickel-copper explorers in the

Fraser Range region.

• 2. To analyse the cost of the different exploration strategies applied

in the Fraser Range.

• 3. To determine which of the exploration strategies appear to have

a higher probability of success when applied to Fraser Range geology.

• 4. To assess the trade-off between cost and probability of success,

using an Expected Monetary Value approach.

Aims

The Approach Undertaken

2014 Calendar Year:

• 1. ~$95,061,000 spent on nickel-copper

projects in region

• 2. 14 companies show active and initial

prospecting ~$40,580,000 cumulatively spent

• 3. Over ~60% of spending made up by 5

companies (excluding Sirius Resources)

Expected Monetary Values (EMV)

Mineralisation: Stages:

Key Findings:

1. Geochemical techniques are more useful than geophysical surveys at the earlier stages of exploration; 2. Companies that implemented a diverse range of techniques produced less false positive results and more nickel sulphide intercepts compared to companies using a narrow range of techniques; 3. Starting initial exploration with aircore drilling may be an effective technique in producing success; 4. The cost of exploration does not appear as critical to company evaluation, compared to the probability of success values. Companies should therefore focus on maximising the range of techniques used.
