#Surpac block modeling by bench software
In simple terms, bankers and mining executives trust Whittle software can help them meet their objectives which are to: maximise return on investment minimise risk ensure all corporate objectives are met Traditionally, Four-D and lately Four-X, have been used to optimise net present value. The Whittle range of optimisation products are recognised as world leaders. Project Financiers Today pit optimisation is a prerequisite before any new open pit project is given approval and allowed to get off the ground. The question is often asked once mining is well underway, ``is the saddle-back barren?'' By employing pit optimisation techniques at an early stage, the explorationist can identify and confirm whether the saddle-back is real or perhaps caused by shortage of data. Such an excavation can result in a saddle-back. Two or more mineralised zones can often co-operate to mine the same portion of waste. There are even techniques to test the blue sky potential of a deposit by artificially extending the depth of mineralised blocks. Using conceptual economic parameters, the resource model could be regularly re-optimised.
#Surpac block modeling by bench update
A well organised exploration program could update a simplistic resource model ``on-the-fly'' as new drillhole results become available. In attempting to prove up an open pit reserve, it would be pointless to sink holes to extend the known depth of the deposit beyond the economic limit of an open pit. One way that this can be done is to drive an exploration program with pit optimisation. Exploration GeologistsĪs development capital becomes harder and harder to raise, companies are becoming smarter with the way they spend their exploration budgets. Both Four-D and Four-X packages will optimise net present value of an open pit for a given set of production and discount rates. Four-D and Four-X introduce the fourth dimension, which is time. Three-D optimises cash flow which is usually adequate for limited life projects. Briefly, if a resource model is optimised for a given set of economic parameters, mining and metallurgical recoveries, and pit wall angles the result will be a single optimal pit outline. Four-X differs from Four-D in that it can optimise multi-element deposits.

Whittle Programming produce the Worldrenowned pit optimisation packages called Three-D, Four-D and Four-X. Who Needs Pit Optimisation? These days when we think of pit optimisation software, we think of Whittle. Deposits covered range from gold through base metals to diverse industrial minerals. Nick is a specialist in pit optimisation and carries out optimisation studies on 30 different mineral deposits each year.
