Dec 20 2017 In one of the main rivers the Shortcleugh Water the nature of the gold is generally similar both in terms of Ag content and inclusion type but a further type of gold relatively rich in Ag and containing distinctive Ni and Sbrich inclusions is also present in 4 adjacent samples in one sector of the watercourse Dec 20 2017 In one of the main rivers the Shortcleugh Water the nature of the gold is generally similar both in terms of Ag content and inclusion type but a further type of gold relatively rich in Ag and containing distinctive Ni and Sbrich inclusions is also present in 4 adjacent samples in one sector of the watercourse

Differences in silver content between different mineralised areas e g Penjom and Raub in Peninsular Malaysia are as apparent from the alluvial samples as from the spread of bedrock gold samples The range in silver content of gold from five soil samples collected near to mines in Malaysia and Zimbabwe is similar to that Differences in silver content between different mineralised areas e g Penjom and Raub in Peninsular Malaysia are as apparent from the alluvial samples as from the spread of bedrock gold samples The range in silver content of gold from five soil samples collected near to mines in Malaysia and Zimbabwe is similar to that

Jun 29 2015 Are you interested in looking for alluvial gold or gold panning Most Tasmanian gold rushes were found by prospectors following leads of alluvial gold It 39s my experience that slate rock bars well above the river can carry gold in places like Mathinna and Mangana and a lot of this article makes good Jun 29 2015 Are you interested in looking for alluvial gold or gold panning Most Tasmanian gold rushes were found by prospectors following leads of alluvial gold It 39s my experience that slate rock bars well above the river can carry gold in places like Mathinna and Mangana and a lot of this article makes good
