Mining and processing of ore at Portia gold deposit. The Portia deposit will be mined using conventional open pit methods. The ore will be transported from the open pit directly to the runofmine (ROM) pad. The mining fleet will include two 250t excavators and six 100t dump trucks.
Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping. The strippingpit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit
1. Mining open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

Openpit mining Openpit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clearcutting or burning of vegetation above the ore deposit may precede removal of the overburden. The
Openpit mining, also known as opencast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an openair pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially useful ore or rocks
Likewise, the mining equipment used today helps reduce waste and chemical exposure throughout the various phases of gold mining. The Basics of Gold Mining and Processing Placer deposits, such as streambeds where people can pan for gold, are not the typical locations used by commercial gold mining companies.
The Relief Canyon project includes three openpit mines, expanding adjacent openpitable gold deposits, and a fully permitted and constructed heapleach processing courtesy of
The openpit and underground mines supply both course gold and refractory ore to a processing plant that includes crushing, grinding, gravity recovery, flotation, oxidation (autoclave) and Carbon In Pulp (CIP) circuits to produce a gold dore product and a high grade pyrite concentrate for shipment to offsite refineries and smelters for final processing.
