STALLED MINING PROJECTS after completion of a "great" feasibility study can be caused by many reasons, and most likley for multiple reasons.
Will the new ore body discoveries be hampered by those same roadblocks and, if so, how will we produce the much needed critical minerals in the future?

LASSONDE CURVE: In 2020 I had written a blog about the Curve. I asked Google NotebookLM to convert the blog text into a explainer video. Here is the result ( a bit dramatic but OK). Pretty amazing tech. https://drive.google.com/file/d/1TDmGRItM7ezJo7WLi6JQIxRIGkpUf1EE/view?usp=sharing

ORE TREND APP: is a newly launched free app to compare the trend in metal prices used in resources and economics.

Compare the prices used in a study against the 3 yr average and see what others are using. Its early so will take time to build up the project database.

MINING TRACKER: One of the things I have been testing out is a mine progress tracker, showing how mines proceed from exploration to production.
I have added 5 companies but anyone can add more projects of interest.
You'll need to log in withan email to get a weblink. Check it out. Thoughts?

MINING APPS: Just for fun and while learning how to use Zite, I created a few online Mining apps to calculate rock value, evaluate interval smootihng, metal production scenarios, etc. Zite takes an Excel file and builds webcode to replicate the logic.

There's a contradiction built into how the mining industry evaluates its projects.

A Preliminary Economic Assessment can include Inferred mineral resources in its mine plan and economic model. The numbers look compelling. Then the feasibility study arrives and the same project looks materially different, not because anything went wrong, but because the rules just got stricter.

Inferred resources occupy a double life in mine studies: market-moving at the PEA stage, yet too geologically uncertain to form a production decision or attract project finance. Understanding how that contradiction exists and how it impacts project economics, permitting strategy, and investor expectations is essential for those evaluating mining assets.

I'll discuss this in more detail in my latest blog post. https://kuchling.com/the-double-life-of-inferred-resources/
