21/5/2013#0183;#32;Typically, it is a lower cost mining method, meaning lower grades of ore are economic to mine. Underground mining occurs when the ore body is too deep to mine profitably by openpit. In other words, the quality of the orebody is high enough to cover the costs of complex engineering underneath the Earths crust.
In the preceding pages some unit costs of sinking, drifting, crosscutting, and drilling have been presented, together with a few costs covering entire churndrilling campaigns. Few figures are available covering the total cost of exploring a property before reaching a decision to develop it for production. However, figures are available covering expenditures for exploration and development at
29/7/2019#0183;#32;The price of gold may fluctuate, but gold will retain its value at all times because of its physics and universal recognition. Due to higher production costs, mining companies need to operate efficiently. In 2019, the average allin sustaining costs (AISC) of mining for gold rose to 1,000 per ounce from 988 per ounce in the last quarter of 2018.
A synthesis of reported AllIn Sustaining Costs (AISC) for 57 Australian gold mines in the period reveals for the first time the clear influence of grade upon cost performance, most evident in goldonly underground mines.
Gold reserves are finite, and pulling new gold out of the ground can be very expensive. In fact, it is common to hear industry insiders cite 1,200 as the allin cost for mining a single ounce of gold.

The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well
Cash cost, introduced in the mid 1990s, is the cost to dig gold bearing rocks out of the ground, process the material and sell the gold. By definition it factors in the basic mining and processing costs
