When people learn that I’m a mining engineer, I’ll normally get perplexed looks and asked what that job is about.    Most never even knew the job existed. So I thought what better way to explain the mining engineer role than by describing the anatomy of a typical Chapter 16 (MINING) in a 43-101 Technical Report. … The post The Anatomy of 43-101 Chapter 16 – Mining (Part 1) appeared first on ..read more

Normally when Major or Intermediate miners advance their projects through the study stages, they usually have the intent to build the mine at some time.  Sometimes they may decide to sell the project if it no longer fits in their corporate vision or if they desperately need some cash.   However, selling the project was likely… The post Mine Builders vs Mine Vendors appeared first on ..read more

This article is about the benefit of preparing (cutting) more geological cross-sections and the value they bring. Geological sections are one of the easiest ways to explain the character of an orebody. They have an inherent simplicity yet provide more information than any other mining related graphic. Some sections can be simple cartoon-like images while… The post Don’t Cut Corners, Cut Cross-Sections Instead appeared first on ..read more

Most of us have seen the typical “grade-tonnage” table or graph, showing ore tonnes and grade at varying cutoff grades. It is usually part of every 43-101 technical report in Section 14.  We may glance at it quickly and then move on to more exciting chapters. Section 14 (Mineral Resources) can be a very complex… The post Grade-Tonnage Curves – Worthy of a Good Look appeared first on ..read more

I recently saw an investor presentation from First Mining Gold about their Springpole Project. The situation is that their open pit is located within a lake and will require the construction of a couple of small cofferdams to isolate the pit area from the lake. The concept is shown in this image. Over the last… The post Mining Under Lakes – Part 1: Examples appeared first on ..read more

We likely have all heard the statement that increasing pit wall angles will result in significant cost savings to the mining operation. What is the potential cost saving? The steeper wall angles reduce waste stripping volumes, which also provide other less obvious benefits. I was recently in a situation where we undertook some comparative open… The post Steeper Pit Slopes Can Save Money appeared first on ..read more
