Horizonte Minerals [LON:HZM] has been awarded four new concession areas adjacent to its Araguaia nickel project which is being developed as the next major nickel project in Brazil.

Horizonte says two new southern concessions, granted for three years and totalling 15,674 hectares, are located in prospective and strategic positions adjacent to the Jacutinga and Pequizeiro deposits at the Araguaia nickel project. The geology of the new areas is an extension of the geology in the adjacent permits hosting the aforementioned nickel laterite deposits. The two new northern concessions, granted for three years and totalling 4,325 hectares, are located south of the recently acquired Serra do Tapa nickel laterite deposit from Glencore. The geology of the area is characterised on their eastern halves by the southern extensions of the mafic-ultramafic igneous unit hosting nickel laterite deposits to the north.

Chief executive Jeremy Martin said: "I am pleased to announce the award of these new concession areas, further consolidating our land position in the Araguaia district. Following the acquisition of the Glencore project in late 2015 we have been actively identifying any new target areas that may have potential to host additional nickel mineralisation adjacent to our existing resources. Furthermore we have a number of other new concession applications pending with the Mines Department.

"We are currently working on integrating the Glencore project with our existing resources, updating the project economics with the aim of delivering an updated 43-101 Pre-Feasibility study in H2 2016. In the shorter term we are focused on the completion of the Environmental and Social base line data collection and working towards obtaining the preliminary mine licence."

Aquarius Platinum's [LON:AQP] revenue fell to USD78 million for the six months to the end of December - 31% down on last time due to lower PGM prices.

Aquarius recorded a consolidated accounting net loss after tax (IFRS) of USD76 million attributable to its share holders for the half-year (5.12 cents per share).

The result included one off non-cash charges of $55 million after tax relating to the impairment of mining assets at Mimosa and Platmile.

EBITDA from controlled entities was $5 million, a $13 million (75%) decease from the prior corresponding period. The Group's decreased EBITDA despite an increase in production was driven by depressed PGM prices which were 29% lower compared to the pcp.

Production attributable to Aquarius increased 4% to 182,911 PGM ounces. All three mines, Kroondal, Mimosa and PlatMile exceeded the pcp production levels whilst maintaining good control over operating costs.

Chief executive Jean Nel said: "Both Kroondal and Mimosa produced ahead of guidance and at reduced costs during the half year. Combined production from Kroondal and Mimosa, of 352,107 4E ounces for the half year is a company record. Both Kroondal and Mimosas PGM unit costs are lower today than 3 years ago in nominal terms (and substantially lower in real terms), a really credible performance by the operating teams lead by Rob Schroder and Winston Chitando.

"That said, the lower PGM prices experienced during the half year significant impaired both Kroondal and Mimosas profitability. In order to ensure sustainability in this macro environment (US$ PGM prices fell to the lowest level in more than a decade) further cost saving initiatives were implemented at Kroondal, and specifically Mimosa, which management expects to result in unit costs reducing further going forward.

"In relation to the proposed amalgamation between AQP and Sibanye, following the approval by AQP shareholders of the amalgamation in general meeting on 18 January 2016, AQP continues to co-operate with Sibanye in fulfilling the remaining conditions precedent to the Amalgamation Agreement and AQP shareholders will be advised of any material progress in due course."
