Metal Recovery Rate How to Interpreted the Mineral

The metal recovery rate can be found in a mining company’s National Instrument 43101 or in a similar applicable international reporting standard Example: When you read a press release in which a mining company announces a resource of 500 million tonnes of 1% copper and a mineral recovery rate of 80% you should actually read that the company announces 500 million tonnes of (1% * 80% =) 08%
