| Some of these veins reached the surface where, in the enclosing gossan, the stibnite has been subjected to oxidation. |
|
| It was found in gossan from a dump of one of the small mines on the southeastern side of the mountain on the World's Fair claim group. |
|
| Here unusually lustrous crystals to 2.5 cm across occurred in limonite-malachite gossan. |
|
| Most are free of matrix, although some of the paler green or greenish-yellow groups are on gossan and are associated with cream to bluish cerussite. |
|
| The pyroxenite host is well mineralized with disseminated pyrrhotite and chalcopyrite forming a prominent gossan. |
|
| This further step forward can be attributed to the presence of iron oxide gossan minerals in the weathered upper zones of copper sulfide deposits. |
|
| It is overlain by up to 7.5 m of gossan and unconsolidated glacial till. |
|
| Subcropping gossan overlying the deposit was also sampled. |
|
| Several Cornish mining words are used in English language mining terminology, such as costean, gossan, gunnies, kibbal, kieve and vug. |
|
| The main yields were lead and zinc ores, in particular galena, blende, cerussite and gossan. |
|
| Gossan, also spelled gozzan, rust-coloured oxide and hydroxide minerals of iron and manganese that cap an ore deposit. |
|
| Gossan Resources Ltd. holds a dolomite deposit at Inwood, Manitoba, on which the company is conducting studies towards a metal project. |
|
| Gossan has examined the Mintek process for the production of magnesium and has evaluated the use of other production methods. |
|
| At least five copper veins were mined named the Sump, Pave York, Low Gill and Gossan Veins. |
|
| Rock sample 2074 taken from Gossan Ridge contains abundant alunite, tremolite, tourmaline, goethite, and quartz alteration of amphibole bearing-alkali rhyolite. |
