New Gold Inc. is a multinational mining company with gold, silver and copper containing assets. It engages in both exploratory and production activity in North America , South America and Australia. Regionally based subsidiaries manage business locally .Many of its mines are polymetallic meaning they hold significant resources in more than one base metal; New Afton contains tens of millions of pounds and ounces of copper and gold respectively while Cerro San Pedro produces a significant amount of gold and silver. Its newest mine to enter operation, New Afton located near Kamloops, British Columbia, began producing gold and copper in 2012. New Gold has made deals with local First Nations groups centered on resource sharing and job recruitment.The New Afton mine raises total production to between 405,000 and 445,000 ounces. The company also produces about 2 million ounces of silver and 12.7 billion pounds of copper. Wikipedia.

This paper serves to outline the reasons for New Afton Mine's decision to pursue ISO 50001 certification, along with details of the implementation process to date. The paper concludes by summarizing the benefits New Afton has realized thus far, and hopes to realize going forward, as a result of the implementation of ISO 50001. Source

The Caspiche porphyry gold-copper deposit, part of the Maricunga gold-silver-copper belt of northern Chile, was discovered in 2007 beneath postmineral cover by the third company to explore the property over a 21-year period. This company, Exeter Resource Corporation, has announced a proven and probable mineral reserve of 1,091 million tonnes (Mt) averaging 0.55 g/t Au, all but 124 Mt of which also contain 0.23% Cu, for a total of 19.3 Moz of contained gold and 2.1 Mt of copper. The deposit was formed in the latest Oligocene (~25 Ma) during the first of two volcanic and corresponding metallogenic epochs that define the Maricunga belt. The gold-copper mineralization is centered on a composite diorite to quartz diorite porphyry stock, within which five outward-younging phases are routinely distinguished. The centrally located, early diorite porphyry (phase 1) hosts the highest-grade ore, averaging ∼1 g/t Au and 0.4% Cu. The subsequent porphyry phases are quartz dioritic in composition and characterized by progressively lower gold and copper tenors. Stock emplacement was both pre- and postdated by the generation of large-volume, andesite-dominated breccias, with tuffaceous matrices, which are believed to be shallow portions of diatremes. The deposit is characterized by a central gold-copper zone and partially overlapped but noneconomic molybdenum halo. The gold-copper mineralization in the lower half of the deposit accompanies quartz ± magnetite-veined, potassic-altered rocks, whereas the shallower mineralization occurs within quartz-kaolinite-dominated, advanced argillic alteration. Upper parts of the advanced argillic zone are characterized by siliceous ledges, some auriferous, composed of vuggy residual quartz and/or silicified rock. The chalcopyrite-pyrite mineralization in the potassic zone was partially transformed to high sulfidation-state sulfides and sulfosalts during the advanced argillic overprint, although the underlying chalcopyrite-bornite assemblage was mainly too deep to be affected. The deposit terminates downward in a sulfide-deficient, potassic-calcic zone defined by K-feldspar, actinolite, and magnetite, which formed at the expense of biotite. A relatively minor, shallowly inclined zone of intermediate sulfidation epithermal gold-zinc mineralization, comprising narrow veinlets and disseminations, abuts the late-mineral diatreme contact. Supergene sulfide oxidation throughout the deposit is relatively shallow, and chalcocite enrichment extremely minor. The Caspiche deposit is thought to have been emplaced at relatively shallow paleodepths, within the southern, flat-bottomed part of the premineral diatreme vent. Earliest porphyry system development, probably north of the present deposit, appears to have been aborted by diatreme formation. Much of the gold and copper in the Caspiche deposit was introduced during the potassic alteration stage, with the highly telescoped, advanced argillic overprint being responsible for only minor redistribution of the two metals, and the addition of arsenic. The late-mineral diatreme was emplaced west of the Caspiche deposit, and caused destruction of only its uppermost peripheral parts. The late-mineral diatreme was both pre- and postdated by advanced argillic alteration. Finally, the intermediate sulfidation epithermal gold-zinc zone was localized by the enhanced permeability provided by intense fracturing along the underside of the upward-flared, late-mineral diatreme contact. © 2013 Society of Economic Geologists, Inc.

In March 2014, New Gold's New Afton Mine became the first mine in North America to be ISO 50001 certified. This was in addition to a whirlwind of several energy performance improvement initiatives, optimizing an energy management information system and an ISO 50001 surveillance audit in November of the same year... making 2014 a remarkable year for energy management at New Afton mine. At the end of it all, we were able to take a breath and ask ourselves the question, "So, we're ISO 50001 certified, now what?" To help answer this, the consultant who assisted the mine with the ISO 50001 implementation, and was present during the annual surveillance audit, was asked about his opinion on energy management at New Afton. In a nutshell, he said that while the implementation absolutely needed to be driven and managed by the Energy Specialist, as things were, the continued success of energy management at the mine was dependent on the Energy Specialist. This was not the desired outcome, nor the understood intent of the standard. Based on this feedback and perspective, a plan was put in place for "Phase 2", to more fully integrate energy management into the systems and culture of the organization, to ensure it was not dependent on any one person. The paper will cover: - Some of the lessons behind the integration of ISO 50001 - Benefits realized as a result of ISO 50001 - Progress in the plan to move from "Implementation to Integration".

New Gold's New Afton Mine ("New Afton") is a 5 million tonne per year operating block cave mine located 8km outside of Kamloops, British Columbia, Canada. The current extraction level is at 615m below surface and the current mining footprint is approximately 800m in length by 120m in width. At its current size, New Afton is one of the smallest producing block caving operations in the world. The ore being mined is a copper-gold porphyry deposit situated within the Iron Mask batholith complex, is bounded by 2 major fault structures and dips near vertically to the south-southeast and plunges southwest. The bulk of the economically viable portion of the deposit is highly jointed and rockmass quality is in the order of 35-55 (RMR76, Bieniawski), placing it in a poor to fair classification category. The case study presented here focuses on a single strike drive ("G") located on the southern abutment of the cave. An excavation that has been subjected to numerous rehabilitation operations and campaigns since caving started early in 2012. Source
