limonite

The pre-feasibility study has highlighted limonite plus saprolite indicated resource of 34.41 Mt at 1.09% nickel from an inferred plus indicated resource of 50.14 Mt at 1.06% nickel using a 0.8% cut off grade; estimated annual production of 24,500 tonnes of nickel and 930 tonnes of cobalt, at an estimated cash cost of USD3.10/lb of nickel, net of by-products including refining costs at USD6.00/lb nickel price and USD10/lb cobalt price; and a post-tax net present value of USD375m.

In addition to the 15.6 km overland conveyor, 46 conveyors with a total length of 6 km have been supplied to convey the limonite, coarse and crushed iron ore, dolomitic limestone, sinter and coke.

Low-grade limonite ore shipped to the Coral Bay and Taganito processing plants, which remain linked to prices at the London Metal Exchange, fetched an average price of $6.02 per pound of payable nickel compared to $4.66 per pound sold a year earlier.

Rio Tuba alone sold 908,000 WMT of saprolite ore and 950,000 WMT of limonite ore to the Coral Bay processing plant.

The rock comprises K-feldspar (microperthite, microcline), plagioclase (minor), quartz, biotite, aegirine-augite, riebeckite, titanite, apatite, zircon, fluorite, epidote, calcite, sericite, kaolin and muscovite and limonite. Sadoros rhyolite is dark gray, banded, jointed, folded, porphyritic and spherulitic.

Nickel Asia is aiming to produce 15 percent more ore this year, having contracted to sell 15.3 million wet metric tonnes of limonite and saprolite ore, but it has no intention of altering its long-term mining plan to favor higher grades, Zamora said.

He held Pakistan has diplomatic and economic relations with North Korea but bilateral trade is still below the potential He informed that North Korea has abundance of natural resources like coal, limonite, steel, graphite and lead.

The only exceptions are the geological mapping carried out by the Czech Geological Survey (Baburek, 2001; Baburek et al., 2001) and a few older specialized studies such as a report on limonite crusts in Strasin Cave (Kukla and Skrivanek, 1954) or research on the Posumavsky Karst (e.g.

The primary mineralogy of this hole is similar to the other holes with dominant muscovite and biotite and accessory limonite, hematite and chalcopyrite.

This year, some busy fellows from Bougafer Minerals & Fossils (bougafermaroc@hotmail.com) of Midelt, Morocco had a single flat in which thumbnail and miniature-size specimens of limonite pseudomorphous after pyrite rolled and jostled about; these were found in August near Imilchil, Morocco, and are a new item from that increasingly important locality.

ANTAM will continue to focus activities at Halmahera and Sulawesi, to further delineate ANTAM's holdings of low-grade nickel ore (limonite), high-grade nickel ore (saprolite) and Low Grade Saprolite Ore (LGSO).
