('PJX' or 'the Company') is pleased to announce that recent drilling intersected a zone with multiple layers of massive sulphide mineralization on the Vine Property in the historical Sullivan Mine District near Cranbrook, British Columbia Canada.
The hole intersected 10.55 m of sulphide mineralization, including 5.17 m of massive sulphides from a down-hole depth of 653.2 m.
Chemical reaction of heavy metals sulphide by this acid as well as ferric iron resulted in production of sulphur in the form of passive film/layer.
Problems are also encountered during crushing and handling processes, where sulphide ores are commonly introduced to humid air and oxygen, promoting self-heating.

Operation of the deposit discovered by Azerbaijani geologists in 1998 consists of two phases: ground (oxide) and underground (sulphide) phases.
Hydrogen sulphide is a colourless gas and, being a weak acid, is highly soluble in water.
"Iron sulphide scale formations cause well failures and, therefore, result in lost production and costly repairs," says Dr Jonathan Wylde, global head of innovation for Clariant Oil Services.
