What is reserve estimation in mining? In mining, ore resource and reserve estimation is used to determine both the quantity and quality of an ore deposit, also called tonnage and estimated economic value. It can be performed initially to assess mineral resources, but also along the mining process to calculate the remaining ore reserves.
The EV-to-reserves ratio is good for the mining industry. "Enterprise value" reflects the company's total value. "Reserves" refers to geologic reserves that the business owns.

When reading a company's press release announcing the mineral resources or reserves of a polymetallic deposit, it's common to see them reported in metal equivalents of the primary metal.This involves multiplying the secondary mineral(s) by their current prices, and then dividing the result by the current price of the primary mineral in the deposit to obtain the …
calculation. This section is dedicated to the different approaches for reserves calculation. A mining operation can never recover all of the in-situ resources. Some portion of the deposit will be inaccessible or unprofitable to mine. Recoverable reserves are a subset of the resources that can be economically and technically mined.
Resource and reserve estimation is a critical step in mine development and the progression from mineral exploration to commodity production. The data inputs typically change over time and reflect variations in geoscientific knowledge as well as the modifying factors required by regulation for estimating a reserve. These factors include mineral ...
By definition, the reserves should be derived from the mine designs or mine plans and cannot be obtained by simple factoring of the mineral resources (JORC Code 2012).Therefore, estimation of the ore reserves requires various inputs from a mining engineer who is a key member of the ore reserves estimating team.
For reserve calculation, the mineral deposit is transformed into an analogous geometric body made up of one, several, or an aggregate of close-order …

If you are a fully operational pit or quarry and are expanding onto permitted land, it may be appropriate to conduct an extensive investigation of the reserves in the new mine area. Not only will the information gained in the assessment be used for financial considerations, it can also be extremely valuable for use for developing the mining plan.
The study on mineable reserves may include diluting materials and allowances for losses, which occur during mining of the material. Mineable reserves are sub-divided into probable mineable reserves and proven mineable reserves. A proven mineable reserve is the economically mineable part of the measured resources, which represents the …
