The mineral reserves and mineral resources have been developed from a computerized block model that is based on a drill hole database incorporating a total of 233 drill holes and 181,326 feet of drilling that continued through to the end of 2012. In addition to the drilling program, the company re-assayed more than 6,000 historical pulps to obtain gold and silver data. The mineral reserve has benefited from additional geotechnical drills holes that allowed the pit wall slopes to steepen due to improved rock conditions

OPERATING COSTS

Average cash operating costs, net of [by-product credits] and using the base case pricing scenario, are estimated at US$0.93 per pound of copper produced during the first five years of production and US$1.15 per pound of copper produced for the life of mine. On an equivalent copper basis, cash operating costs average $1.56 per equivalent pound of copper produced over the life of mine.

On a cost per ton basis, cash operating costs are estimated at $11.24 per ton processed, excluding by-product credits. Cash operating costs include mining, processing, site general and administration, treatment and refining, and concentrate transportation costs.

Operating Cost $/ore ton
Mining Cost 2.54
Process Cost 4.85
General Administration
Cost 0.56
Treatment & Refining
Charges 3.29
Total Operating Cost 11.24

CAPITAL COSTS

The total initial capital cost for construction, mine pre-development, commissioning and owner's cost is estimated to be $372 million. Sustaining capital will total $61 million over the life of the operation.

The project is a brownfield redevelopment project in a stable region with excellent access to existing infrastructure. The project will realize savings through the reuse of significant infrastructure, which the project engineers value between $55 to $65 million, that remains from the original mine.

PERMITTING STATUS

Permitting efforts for the Copper Flat Mine have been in process since 2010. Baseline Data has been collected within the mine permit boundary and in surrounding areas over a 12-18 month time frame and included studies of air quality, vegetation, wildlife, surface water, groundwater, cultural resources, geology and soils.

Due to the fact that some of the land in the proposed mine permit boundary is managed by the Bureau of Land Management, an Environmental Impact Statement is required. Work on the Environmental Impact Statement is progressing; scoping and public meetings were conducted in January 2012. Efforts are currently focused on finalizing a Draft Environmental Impact Statement which will then be publicized for public comment.

Various additional studies have been conducted and are being used to inform both state permit applications and the current federal evaluation process. These studies include but are not limited to socioeconomic benefits of the mine, highway conditions and traffic impacts, geochemistry of the site, and aquifer characteristics. Permitting efforts at a state level are well underway and an air permit was granted by the New Mexico Environment Department Air Quality Bureau in June 2013.

Management continues to engage with the OSE to secure the appropriate consents and permits for project water rights. As the company progresses its arrangements in this regard, the appropriate disclosures will be made.

MINING AND PROCESSING

Copper Flat is a porphyry copper-gold deposit that is located in close proximity to the surface and amenable to open pit mining methods. The pit operations are planned to use standard mining equipment, including: 45,000 lb., single pass rotary blast hole drills, 19-cu-yd front-end loaders, and 100 ton off-highway haul trucks. The Mine plan include a mine support fleet comprised of several track and rubber-tired dozers, motor graders, and 10,000-gallon water trucks. Material mined totals 158 million tons of ore and waste over the life of mine at an average stripping ratio of 0.40 tons of waste per ton of ore. The mining rate peaks at 17.5 million tons of total material per year.

The construction program benefits from the use of existing infrastructure and the timeframe expected to construct and commission the project is estimated to require

18 months. Following construction, the project schedule includes 11.1 years of ore processing and four years for reclamation and closure.

Ore will be processed through a standard crushing, grinding and sulfide flotation concentrator to produce a copper-gold-silver concentrate and a molybdenum concentrate. The Copper Flat concentrator is scheduled to process 10.8 million tons per year for the first five years of production and 9.9 million tons per year for the remainder of the mine life when harder ores are encountered at depth in in the deposit. Copper production is projected to average 70 million pounds per year during the first five years of operation and 57 million pounds per year when averaged over the full life of mine.

The Copper Flat ore lends itself to common crushing and grinding practice and standard flotation reagents and the mill is designed to have a simple gyratory crusher and SAG/ball mill grinding circuit followed by a conventional floatation circuit to produce separate copper and molybdenum concentrates. Metallurgical testing shows the Copper Flat ore contains coarse gold that is recoverable through physical separation and gravity separation equipment, this equipment is included in the process flow sheet to improve gold recovery. As a result of metallurgical test work, the expected life of mine recoveries are projected to be: copper 93%, molybdenum 78%, gold 72% and silver 83%.

The mine will produce approximately 100,000 tons of copper concentrate and 1,300 tons of molybdenum concentrate per year for the life of mine. The copper concentrate is expected to assay 27% to 30% copper based on lab tests and actual plant performance achieved by Quintana Minerals in the past operation. The molybdenum concentrate is expected to assay 50% to 60% molybdenum oxide. ICP analysis of the copper concentrate determined that the concentrate is expected to contain very low concentrations of potential smelter penalty elements.
