What Is Open-Pit Mining? (with picture)
Open pit mining is just so destructive and awful I don''t know how it can be allowed anywhere, let alone in the places it''s often done. They basically just strip off huge chunks of land so that nothing can grow there and in the process they end up polluting nearby water supplies and disrupting every other local natural process, since they use loud, obtrusive machinery.

How to profit from low-grade gold mines
Open pit vs underground: Of utmost importance to the cost of extracting gold is where the gold lies within a deposit. A deposit of disseminated gold (small particles of gold distributed throughout the rock) close to surface will be open-pit mined, while gold found in often-thin veins hundreds of meters below surface is mined using underground methods.

For example, a marginal gold producer that has AISCs of US$1200 per ounce is sailing close to the wind based on the current gold price of around US$1280 per ounce.

Open Pit Mining
Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.
