Market comm entators contin ue to discuss gold hitting US$2,500 an ounce within the year. Global antimony demand has been on the rise for the past 20 years and the strategic metal continues to top critical raw materials lists from those of the British Geological Survey to the North American automotive industries. Both outlooks are well-timed good news for Northwest Resources Ltd. (ASX: NWR) (“Northwest”); the explorer-developer advancing the Nullagine Gold and Antimony Project (“Nullagine”) in the eastern Pilbara into one of Australia’s highest grade underground mines with production from 2013—complete with current JORC resources of 402,000 ounces gold (Au) and 9,000 tonnes of antimony (Sb) and plans to at least double that existing inventory backed by uncapped exploration upside. The buzz surrounding Nullagine starts with the Blue Spec Shear project where production is on track to take place next year; an east-west trending shear zone which outcrops over 16 kilometres within Nullagine, home to high grade gold-antimony deposits and vast potential for future discoveries. But importantly, while the area has been on the radar for more than 50 years, it appears that the missing ingredient has been Northwest: The team with the right approach to mining the deposits and MARCH 2012 ? The International Resource Journal 7 innovative processing strategy to handle historic metallurgical gripes, set to see the project into nearterm production and attract international would-be buyer interest en route. “At the Blue Spec Shear project, the development approach we’ve taken is to operate the Blue Spec and Golden Spec deposits at the same time, and also use the development as an exploration platform,” says Northwest Managing Director John Merity, describing the company’s plans for concurrently targeting initial 2013 output and ongoing resource definition. “The real opportunity of working both Blue Spec and Golden Spec together is the potential to discover another Spec between them and to expand the potential of the high grade system.” Blue Spec-Golden Spec is shaping up to be one of Australia’s highest grade narrow vein gold projects, with imminent production supported by Northwest’s low cost cutting-edge processing strategy. Furthermore, coupled with Nullagine’s Camel Creek Trend project—a 50/50 joint venture between Northwest and developer Millennium Minerals Ltd. (ASX: MOY) (“Millennium”) on track to become the second producing mine in 2015—it’s safe to say that the company is building a high grade, highly profitable mining hub with plenty of opportunities for resource growth
To 2013: Blue Spec by numbers With a JORC resource inventory of 329,000 ounces at 20.7 grams per tonne gold and 7,300 tonnes Stibnite currently defined across Blue Spec and Golden Spec just 950 metres apart from one another, grounds for operating both deposits together for the first time are well-founded. Defined to around 300 metres, Golden Spec wouldn’t support a mining operation on its own; despite its high grades, it wouldn’t produce enough annually. Defined to around 850 metres, Blue Spec could be a small standalone mine, but combining them gives Northwest desirable scale and operational flexibility. “By operating the two undergrounds at the same time, mining can continue at Golden Spec whilst blasting is occurring at Blue Spec, for example, whereas blasting at a single underground operation would normally require all underground staff to be sent to the surface resulting in operational downtime,” Merity explains. By approaching the mining of deposits in a manner allowing long-term exploration to coexist with targeting minimal cost 2013 production, Northwest is able to advantageously add to its resource inventory while establishing itself rapidly as a high grade gold producer. The company has begun first stage feasibility studies for mining, engineering, capital, operating and offtake pricing—but the plans that have captivated onlookers (and thwarted the best efforts of past explorer-developers) are those of the company’s innovative metallurgy and processing strategy. Processing gold-antimony concentrate Merity says that the presence of antimony poses a hefty value-adding by-product for the future operation, particularly given that both mining methods and antimony market demand have improved greatly since Anglo American ceased exploration at Blue Spec in 1978, largely due to low processing recovery rates. “Previous owners have had a lot of difficulty when trying to separate the antimony from gold because of the nature of the ore up there. They’ve been forced to walk away from what would otherwise have been tremendous gold mines given the ounce grade in the deposits,” he explains. “We’ve pursued a processing strategy that doesn’t seek to separate the antimony from the gold. We can produce a gold-antimony concentrate through a flotation process and achieve pay rate for that which would match industry standard recovery grade were we to pursue a full recovery process onsite.” MARCH 2012 ?

Adopting flotation processing will enable Northwest to avoid complex hydrometallurgical separation of the metals, and given antimony demand it may provide another 10-15 per cent in equivalent gold revenue. The team is presently conducting an extensive metallurgical testwork programme and diamond drilling to obtain approximately 950 kilograms of metallurgical core samples from the deposits. Results will reveal what the flotation concentrate will look like, how low on penalties it is, and assist in refining pricing discussions. Discussions are underway with Chinese smelters who may take the concentrate and use pyrometallurgy to treat the concentrate, Merity says, and they aren’t the only parties eyeing Blue Spec’s imminent production offering. “Another opportunity available to us is to toll treat the gold-antimony concentrate in the U.S.,” he explains. With environmental permitting underway, the preliminary study report and financial evaluation due for completion within the second quarter of 2012 and the final study report and financial evaluation expected by the year-end, tackling the metallurgy and processing strategy (warranting discussions with potential buyers) signifies that Northwest has cracked the right formula for Blue Spec-Golden Spec; a key breakthrough which will
likely prove ever more pivotal as further resources are added to the project’s inventory. More high grade resources & mines Given the complex mineralogy, time and cost of drilling and range of grades evidenced across the less-drilled lower Blue Spec zone, well-drilled upper Blue Spec zone, Golden Spec lower zone and other potential Specs between them, finding belowsurface deposits of this calibre isn’t easy. Deposits range between one-to-four metres in width, Merity says, and while Blue Spec was discovered due to its outcrop, one could “spend a lifetime drilling from surface between Blue Spec and Golden Spec and never hit a blind shoot there.” The resources defined and incoming metallurgical results continue to underpin plans for the 2013 production profile, but given Blue Spec’s exploration upside, they prove to be the tip of the iceberg. In addition to targeting through put of 100,000- 125,000 tonnes per annum based on conservative vertical advance rates, the company plans to evaluate opportunities to increase grades and at least double its current resource inventory. “And these aren’t fanciful estimates. They really depend on following our noses during operation,” Merity says. “That’s the inherent difference between underground and open pit operations; with open pits you define the entire ore body and that’s it, whereas for underground you define as much as necessary to start, then keep following the deposit down until it becomes uneconomic which could be as deep as one kilometre at Blue Spec.” Given the moderate depths to which Blue Spec and Golden Spec are defined to date, and the great potential to discover another Spec between the two, there remain many opportunities for further discovery and resource expansion. Additionally, given Northwest’s Camel Creek joint venture with Millennium for which reserve estimates for the joint venture deposits are due in the second quarter of 2012, it looks likely that the company will have two operating mines at Nullagine come 2015, and rapidly advance into a multi-mine producer within the next five years. “Blue Spec-Golden Spec could become one of the best mid-size gold mines in Australia in terms of production and cash costs. And by putting together the right team to develop that project, we’ll also be putting together the right team to take on, acquire and develop new projects” Merity says, adding that this team already includes highly respected mine builder Alan King as executive general manager. Masterminding the Blue Spec Shear’s metallurgy and processing strategy has seen Northwest overcome the development hurdle past MARCH 2012 ? The International Resource Journal 11 Current resources at Blue Spec Blue Spec -Upper Zone: 122,000 oz @ 42.5 g/t Au, 2,300 t Sb @ 2.61% - Lower Zone: 132,000 oz @ 17.5 g/t Au, 3,200 t Sb @ 1.38% -2.5 - 4.0m average mining widths Golden Spec -75,000 oz @ 8.5 g/t Au, 2,300t Sb @ 0.84% including 49,000 oz @ 18 g/t Au -1.5 - 2.5m average mining widths project owners have fallen at. Maintaining a steadfast focus on exploration to increase the project’s resource inventory alongside reaching high grade 2013 production is the recipe for long-term project success. Simultaneously, Camel Creek reveals the Northwest team to be adept in attributing focus to its flagship project while firming up a secondary revenue stream, and each advancement continues to prove how abundant Nullagine’s mineralisation and options for project growth truly are. Within the coming months, Northwest will further prove that its metallurgical and processing plans are ideal for Blue Spec-Golden Spec. It will move through its feasibility studies and ready to make the transition from developer to producer, and onto multi-mine producer. There aren’t many juniors who can see through such strategically staged, cost-effective multi-deposit, multi-metal development, but in Northwest, Australia has a startlingly capable emerging high grade underground gold miner. www.nw-resources.com.au
