“…The risk, therefore, could be minimized within given limitations by evolving an exploration strategy which judiciously combines sound geological concepts with economic and commercial judgement at each stage of exploration. Brant (1968), Mackenzie (1973Mackenzie ( , 1981, Snow and Mackenzie (1981), Mackenzie and Belodeau (1984), Eggert (1987), Mackenzie and Woodall (1987), Tilton et al (1988), and Silver (2000) have developed several criteria for assessing risk on investment in mining through mineral exploration using probability considerations to examine actual or likely returns. The "Expected Net Present Value (EV)" and "Expected Rate of Return (ROR)" concepts of Bilodeau and Mackenzie (1979) provide an effective means to estimate the possible risk in investment in mineral exploration.…”
