How to convert your resource into compost without really trying – 7 easy steps

This article was first published in the Snowden newsletter in December 1997. Although 20 years have now past many of the ideas presented in this article are still relevant today.

Ignore the geology, it’s only rocks. What you really care about are the numbers. Do not let a mere fault or shear, or even a different rock type get in the way of a good bag of numbers. Geologists are always trying to find excuses to justify why they cannot tell you with a decent accuracy (say within plus or minus 1.5 percent, to allow them a generous margin of error) where the 23.6 tonnes at 9.634 g/t are going to be today.

Avoid wasting time and money on density studies. Rocks are rocks are rocks. How different can they be after sitting around in the sun for a few billion years? It is a complete fallacy to believe that mere temperature, pressure and deformation regimes can cause density changes within a deposit.

Do not worry excessively about surveying drillhole collar locations. Surveyors are extremely busy individuals, they are much more valuably employed ensuring that the pit floor is no more than 2.361mm high on one side than the other. Besides if the drillers have done their job, the drillhole should be exactly where you left it. And down-hole surveying, that is just too dangerous to go risking losing a $20,000 camera just so you can see where your hole is at. Again, if the drillers have done their job the hole is going to go right where you told it to.

Trust your laboratory procedures, you did a good job setting them up six years ago, did you not? Why would they have changed now, just to inconvenience you? Have faith in the written procedure. Check assays are a waste of everyone’s time, not to mention a hideous consumer of scarce exploration dollars.

Use all the default values that are in the software the first time you get into a relevant screen. Software default values are the ones the program tests most efficiently on, so they must be correct. Make sure your resource is a 1000m x 1000m board, 10m think. No problem. Remember to arrange all the assays in evenly spaced 1m composites along a 10×10 grid.

Leave out the considerations about the selective mining unit. That is for the engineers to worry about. Selective mining units are a red herring that prevent the aesthetic modelling of a resource. The resource is a pure numerical form that should not be confused with the day to day chaos of an operating mine site. Keep your resource pure.

Most importantly, go with the gut feel. Nothing is more acute than a finely-tuned, high-performance gut when it comes down to the nitty-gritty of resource work. Why drill when you do not have to? You can use your exploration dollars to maximise returns by relying on that tried and true standard, the gut feeling.
