How confident are you in your data quality when it comes time for EOM reporting?
Would you build a house without following a plan? Then why would you mine a resource without following the plan?
We have seen some AMAZING excel spreadsheets in our travels with some equally amazing macros providing the basis for reconciliation reporting in our industry. But what happens when the owner leaves, the macros break or you simply have a complex orebody or a long mine life?
Every block estimated in a model is independent of every other block estimate and each block should be estimated with the best possible configuration of samples and the most reasonable topcut. Snowden’s Supervisor software provides tools that ensure that each block is estimated with the best possible combination of parameters (LKNO) as well as the most reasonable LOCAL topcut (local transition topcut model).
Mining investors are often faced with lots of technical jargon around Mineral Resource statements. The thoughts in this article, written by Snowden’s Jeremy Peters, are not exhaustive, but are a simple list of things to look for when interpreting these statements.
NPV is a great tool. But used blindly it might not give the outcome you need for your project. In this blog, Tarrant Elkington, Global Manager, talks about the power of incremental analysis.
What constitutes the best graphite exploration target at a project? Snowden’s Executive Consultant, Andrew Scogings,, outlines his approach.
Barite is naturally-occurring barium sulphate that is utilised primarily for its high density, in addition to chemical inertness and relative softness.
Graphite is an allotrope of carbon and is grey to black, opaque, very soft, has a low density and a metallic lustre. It is flexible and exhibits both non-metallic and metallic properties, making it suitable for diverse industrial applications.
This article was written by Executive Consultant, Andrew Scogings. Bentonite is sometimes called the ‘mineral of a thousand uses’ and is characterised by properties such as its ability to swell in water, to act as a ‘natural glue’ or ‘bond’, special rheological properties when added to water (e.g. thixotropy), high surface area and exchangeable cations. These properties may be modified by treatment with acids, soda ash or other compounds such as polymers. Bentonite finds application across a wide range of markets including foundry (metal casting in sand moulds), clumping cat litter, iron ore pelletising, edible oil, wine and beverage purification, oil and other exploration drilling, civil engineering, animal feed and paper manufacture. Approximately 16 to 20 million tonnes of bentonite … Read More
