Of the total volume of ore the miner shipped, 9 million WMT was saprolite
ore and 8.
In a disclosure to the Philippine Stock Exchange, Nickel Asia said its shift to higher-value saprolite
ore 'resulted in a significant improvement in earnings.
0m in saprolite
in trench MEM17-002 located 110m to the northwest of the MEM showing.
This led to the recent granting of a third party exploration work program to delineate the under-explored saprolite
Drilling at Sona Hill follows the discovery of anomalous gold values distributed in saprolite
discovered during the 2011-2012 regional geochemical survey of the upper Puruni Concession, and is designed to further delineate gold mineralisation encountered in saprolite
and fresh rock drill intercepts during the initial reverse circulation and diamond drill programs.
The main thing that surprised me on the way was the appearance of a large amount of quartz in a saprolite
taken from a 1-meter depth," Selck said.
Recent test work has further optimized the organic acid leaching process, which has achieved nickel extraction of up to 98% from the saprolite
material after less than 30 minutes.
The programme includes 10 to 15 holes to depths of between 150 to 300 metres to test the saprolite
and bedrock zones present in two areas of the Marudi Mountain property.
09% nickel and 49% iron; and high-grade saprolite
intersections with 1.
The intact lateritic profile was mostly formed by weathering of granitoids and other rock types and these profiles commonly consist of sand and pisolitic gravels over lateritic duricrust (cemented ferruginous material), mottled and pallid zones (quartz and clay rich materials), saprolite
and saprock (isovolumetrically weathered materials with retention of parent rock fabric), and rock (Anand and Paine 2002).
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
In addition, changes in Ca, Ba, Rb, Zn, Pb, Co, and other elements in the oldest saprolite
indicate element mobility during weathering.
