Mining Briefs: International Goldfields, Aruma and more

IN Mining Briefs today: drill hits for International Goldfields and Aruma; Lynas warns shareholders of misleading investment offers; Mount Burgess contact the High Commission; Comet Resources looks to Krgyz Republic; and sales update from Atlantic.

International Goldfields has received the final two results from drilling at its Uniao prospect, part of the Ouro Paz joint venture in Brazil.

The company reported results of 5.7m at 11.7gpt gold from 50.4m including 3.6m at 17.8gpt gold from 51.5m, 4.3m at 15.86gpt gold from 72m, 5.8m at 2.77gpt gold from 106m and 1m 62.28gpt gold from 72.5m.

The company said the intercepts extended mineralisation and refine targeting for additional drilling.

Aruma Resourceshas released results of recent reverse circulation drilling at its Glandore project in Kalgoorlie, with new gold zones confirmed.

Significant hits included 5m grading 4.3gpt gold intersected at the Steves zone and 4m grading 1.35gpt gold including 3m grading 1.64gpt.

Lynas Corporation has warned shareholders of an entity going by the name of Lyens International Investment Group. It is claiming to be part of the Lynas Group for the purpose of soliciting investment.

Lynas said it had absolutely no connection with the entity.

Mount Burgess Mining has contacted the High Commission for Australia in Pretoria, South Africa, to seek rectification after an extension of its prospecting licence, which contains its Kihabe and Nxuu zinc-lead-silver project, was rejected by the Ministry of Minerals, Energy and Water Resources.

The company has submitted a summary of the situation to the Australian Deputy High Commissioner. And will keep the market informed of any progress.

Comet Resources has secured rights to acquire an interest in gold projects in the Krgyz Republic.

Comet can elect to acquire KG to own the option to acquire a controlling 90% interest in the three exploration licenses, which are prospective for gold mineralisation.

Comet has the opportunity to undertake six months of due diligence over the licenses before a decision to exercise its option is made.

Atlantic said it sold 21.8 t of vanadium from its Windimurra vanadium project in April.

During the month, the focus remained on resolving the last non-performing part of the Windimurra plant, the beneficiation plant within the crushing, milling and beneficiation circuit.

Work at the plant to resolve design issues remains on track to be finished by May/June.

Barrick renegotiates Pueblo Viejo agreement

BARRICK Gold and its partner, Goldcorp, have reached agreement with the Dominican Republic government over the amendment of the Pueblo Viejo special lease agreement that will give the country half of cashflow over the next three years.
The $US3.7 billion ($A3.6 billion) mine reached commercial production in January and the Dominican government has made it clear it wanted larger returns.
Barrick said the new agreement, which came after eight months of discussions, preserved the economic value of the mine, while addressing the fiscal objectives of the country.
The company said the new in-principle agreement would increase government revenue and bring it forward.
Possible amendments to the agreement include the elimination of a 10% return embedded in the initial capital investment, an extension to the period over which the partners will recover their capital investment, a delay of application of net profits interest deductions and a reduction in depreciation rates.
Barrick said a graduated minimum tax would be established, which would be adjusted up or down based on metal prices.
The annual minimum tax rate will be reset every three years and will be equivalent to 90% of the taxes that would have been payable by the partners over the same period.
Barrick said, based on the proposed changes, it anticipated there would be a 50/50 split of the expected cashflows between the partners and the government between now and 2016.
Expected tax revenues to the government would be around $2.2 billion at a $1600 an ounce gold price.
The Dominican Republic government’s economic benefits from the changes are expected to amount to $1.5 billion.
The agreement will also likely set a corporate income tax rate of 25%, a net smelter royalty of 3.2% and a net profits tax of 28.75%.
Pueblo Viejo is expected to produce over 1 million ounces of gold per year in its first five years at all-in costs of $500-$600 an ounce.
Barrick owns 60% of the mine, while Goldcorp holds the balance.
The existing agreement will continue until amendments are made.
The changes are still subject to the negotiation of a definitive agreement, which will require Barrick and Goldcorp board approval, as well as the approval of project lenders, and Dominican approval.

In February Dominican President Danilo Medina said he was seeking to amend Barrick and Goldcorp’s contract for the new mine to give his people a larger share of the profits.
"In other words, during the early years, for every $US100 of income the export of gold and other metals, Barrick would receive $97 and the Dominican people $3," he said in a translated statement.
"That is simply unacceptable."
He added that gold could “only be extracted, processed and exported if the distribution terms of revenue generated by the exploitation of this non-renewable resources were fair and favourable to the Dominicans”.
“And at the present time they are not.”
There was further controversy in March when a gold shipment from the mine was detained by Dominican customs authorities.
Pueblo Viejo is one of Barrick’s growth projects, the other being Pascua-Lama on the border of Chile and Argentina, where it is also having issues.
Last month construction on the Chilean side had to be suspended after a court injunction was filed over environmental concerns.
Barrick shares jumped 8.6% in Canada overnight, while Goldcorp was up more than 6%.

Thousands feared jobless as Norilsk Nickel plans Botswana operation shutdown

According to newspaper Botswana Guardian, the world’s largest nickel and palladium producer Norilsk Nickel is planning to shut operations at its Botswana-based Tati Nickel mine.
The effects of a shutdown may result in the retrenchment of about 1 200 employees.
The tabloid said that the Russian-owned Tati mine’s management undertook an assessment tests and concluded that the copper and nickel mine is has no value.
It has been revealed that the target was to ascertain whether the Norilsk would achieve 1200 t production output between 25 February 2013 - 25 March 2013. Thus far the company has only been able to achieve 600 t for that period.
Meanwhile, it was reported in April 2013 that Norilsk Nickel may suspend operations at its Tati Nickel mine in Botswana after a sharp drop in metal prices.
Global prices for nickel, a key ingredient to make stainless-steel, had fallen 10% since the start of 2013, forcing the company to review some production, Norilsk said in the prospectus for a forthcoming Eurobond issue.

Davis eyes mining investment

ONLY days after losing his job due to the Glencore-Xstrata merger, Mick Davis has reportedly hired Goldman Sachs to help him set up a mining fund.
Mick Davis
The 55-year-old South African finished up at Xstrata on Wednesday and has wasted no time plotting his highly anticipated next moves.
The Financial Times reported that Goldman would help raise billions for the fund, which would buy stakes in mining assets, citing an unnamed source involved.
Bloomberg previously said former Xstrata chief financial officer Trevor Reid, who also left when the merger was completed, would be joining Davis in his new ventures.
Davis spent 11 years at the helm of Xstrata, overseeing acquisitions like Mount Isa Mines and Falconbridge, and growing the company into one of the world’s largest mining houses.
Davis was initially meant to lead the enlarged Glencore Xstrata, but when the merger became a takeover of Xstrata, Glencore reneged and said Davis could be chief executive for six months, after which its own CEO, Ivan Glasenberg, would take over.
It emerged last month that Davis would leave when the merger was completed on May 2.
Davis is still entitled to six months of pay and entitlements equating to £4.6 million ($A7 million), in addition to the previously agreed sum of a year’s salary, 2011 bonus and other benefits and pension.
He will act as a consultant until the end of June, though will not be paid consultancy fees – instead he will be entitled to up to 30 hours of private use of an Xstrata aircraft.
Davis will take a sub-lease of Almack House, Xstrata’s former London offices, until March 15, 2017, at the same rent Xstrata pays, with a rent-free period up to the end of March next year, though he will pay the company the book value of the furniture and IT equipment at the end of the lease.
Meanwhile, the Australian Financial Review reported yesterday that former BHP Billiton aluminium, nickel and corporate development CEO Alberto Calderon was looking to set up a private equity fund to invest in Latin American mining projects.
And Bloomberg reported this week that former Barrick Gold CEO Aaron Regent, who was sacked last year, has started to invest in assets through his company Magris Resources.
Magris was reportedly one of the company’s that bid for BHP’s Pinto Valley copper asset, which was sold to Capstone Mining Corp last week for $US650 million.

Village acquisition of Continental Coal stake receives final approval

South African diversified mining company Village Main Reef has received South African Reserve Bank approval for its acquisition of a shareholding in ASX- and Aim-listed thermal coal production, development and exploration company Continental Coal.
This was the only outstanding condition to Village’s proposed strategic financing transaction with Continental.
With final approval now received, the companies expected the completion and financial settlement of the placement next week, followed thereafter by the issuance of shares to Village.
Continental and Village had previously entered into binding financing agreements, which would see Village subscribing for 100-million ordinary shares in Continental at an issue price of A$0.08 a share, raising a total of A$8-million.
The transformative deal would also give Village the option to acquire further Continental shares on the market at a price of up to A$0.10 a share, thus increasing its shareholding to 19.9%.
The transaction reflected Village’s continued diversification strategy, while maintaining its investment in cash-generating assets.

Alcoa to invest $275m in automotive aluminium sheet production

US-based aluminium products producer Alcoa on Thursday said it would invest $275-million over the next three years to expand and convert capacity at its rolling mill in Alcoa, Tennessee, to support automotive producers’ plans to use more aluminium sheet to increase fuel efficiency, safety, durability and performance of cars and light trucks.

Alcoa said it wanted to meet the growing demand for light, durable and recyclable aluminium sheet for automotive production.

Alcoa had previously announced a $300-million expansion of its Davenport, Iowa plant, which was expected to be complete by the end of this year.

“More and more auto producers are turning to aluminium to increase the fuel efficiency and quality of their vehicles – we anticipate a quadrupling of auto sheet volume by 2015 and a tenfold increase by 2025,” Alcoa chairperson and CEO Klaus Kleinfeld said in a statement.

Alcoa, which on Wednesday said it would review 460 000 t of smelting capacity over the next 15 months for possible curtailment, in an effort to maintain the company’s competitiveness, as aluminium prices have fallen more than 33% since their peak in 2011, on Thursday said the Tennessee expansion could add 200 full-time, high-value jobs when complete.

The project would convert some of the plant’s can sheet capacity to high-strength automotive aluminium capacity, as well as install incremental automotive capacity.

The Tennessee expansion was scheduled to begin this month and be completed by mid-2015.
When completed, the plant would be a critical supplier to both the packaging and automotive markets.

The company said much of the volume for the automotive expansion was already secured under long-term supply agreements. asa20130503

Sustainable mining practises: reducing diesel use for mine

Ore movement is typically the single largest energy-using activity for an open pit iron ore mine, with haulage alone accounting for about 30% of a site’s total energy consumption. Other vehicles and mobile equipment used for ore extraction, stockpiling, and loading can account for another 25% to 30%.

The most commonly used fuel for haulage is diesel and with the decrease in diesel fuel rebates, operating costs have increased significantly. These costs are set to continue rising in 2014 when transport is included in the carbon pricing mechanism – potentially making ore movement off-site more expensive, whether by truck or rail.

Mapping diesel fuel use both onsite (mine fleet) and off site (ore transport) highlights levels of diesel fuel consumption and wastage. This can assist mine operators in identifying potential fuel reduction opportunities to reduce operating costs, optimise operating efficiency, and meet internal and external drivers in sustainability.

The first step in mapping your diesel use is to recognise consumption levels by equipment type e.g. heavy mobile equipment such as excavators, drill rigs, loaders, haul trucks, dozers and graders; medium-size equipment such as service trucks; on-site light vehicles; and off-site transport such as road trains or locomotives. Categorising the equipment by activity and type will help determine the fuel used on-site and off-site.

Off-site ore transport is usually operated by a third party who may pass-through the equivalent carbon cost increase to the mine operator, unless contracted otherwise. It is important that an operator communicates to all transport contractors, their desire to reduce operating costs through improved fuel use. Working together with the contractor by assisting them to assess their fuel consumption may potentially result in fuel reduction.

Once the fuel use has been categorised, it is possible to see where the largest fuel use has occurred and therefore where the greatest savings opportunities may lie. The next step will then be to consider the other parameters of vehicle and equipment use, some which will be within the control of the miner to change (e.g. idling times) and others which the miner may be able to influence (e.g. driver training) or may not be able to influence (e.g. distance from mine to port).

Those iron ore miners who participate in the Energy Efficiency Opportunities (EEO) program can use the EEO assessment framework as reference for change and report the energy saving projects as part of their organisation’s assessment requirements. Either way, whether liable under the EEO or not, improving fuel use will reduce operating costs. And with around 20 per cent of operating costs being from energy use, a 5% decrease can make a big difference to the bottom line.

Miners in Australia have been trialling and implementing a number of fuel reduction activities.

These include fuel additives for fleets; reducing the number of stops required by the haul trucks; using dynamic real time dispatch system to optimise haul truck movements and reduce idling times; trialling an auxiliary battery on haul trucks for operating the cab’s air-conditioner during idle times, allowing the engine to be turned off; and improving haul truck management e.g. engine management, driver training, maintenance tracking, load management, and tyre pressure management.

Other leading practice fuel reduction activities include using lighter weight and more fuel efficient vehicles and equipment; implementing in-pit equipment maintenance; using electric driven mobile equipment and locomotives with regenerative breaking; replacing truck haulage with conveyor systems from the mine face to the plant, combined with in-pit crushing to reduce ore size; and optimising digging schedule to reduce the number of shovels required at any given time.

Trials of each of the above fuel reduction activities have been shown to reduce diesel consumption by up to 5%. Using cleaner fuel alternatives and improving fuel efficiency of the mine fleet and ore transport options reduces operating costs, improves air quality, and reduces the miner’s carbon liability.
