Skarn

The fine-grained “skarn” degraded easily and produced only a 40 to 50 per cent extraction level since the related rapid fine formation reduced bacterial activity and caused iron hydroxide precipitation. ❋ Unknown (1984)

The Dolly Varden area is recognized as a classic eastern Great Basin district with base and precious metals associated with upper Paleozoic sediments intruded by Cretaceous auriferous magmas, which is a similar geological setting to the Battle Mountain Fortitude skarn gold type deposit in east central Nevada.

The Kangas Zone represents a north-south trending zone of skarn and replacement style mineralization within siltstone, calcareous siltstone and minor limestone located along the north flank of the central ridge of the Justin property. ❋ Unknown (2012)

QFP's are associated with the skarn and porphyry copper deposits of the Nevada basin area.

The primary target for the program was trench SN97-2 which returned historic values of 2.38 g/t Au over 22.5 metres. 2011 drilling returned anomalous gold and copper values from the calc-silicate skarn adjacent to porphyry dikes. ❋ Unknown (2012)

Recently completed drill hole ACMD-008, which was designed to test for up-dip (near-surface) extension to previously identified gold-copper-molybdenum mineralisation, intersected approximately 30 metres of cumulative skarn alteration in multiple zones. ❋ Unknown (2010)

The ring of skarn deposits has not been systematically explored, and the central intrusive complex offers an interesting bulk-tonnage target. ❋ Unknown (2010)

Visible sulphide mineralisation was identified in various skarn and breccia zones, with an alteration zone recorded between about 46m and 54m downhole including encouraging chalcopyrite, and locally-strong molybdenite mineralisation. ❋ Unknown (2010)

Alturas 'exploration strategy is focused on the discovery of large epithermal gold mineralized deposits and copper-gold porphyry/skarn deposits in Peru and Chile. ❋ Unknown (2010)

It should be noted that molybdenite and chalcopyrite mineralisation was observed in other skarn and breccia zones. ❋ Unknown (2010)

The discovery supports Peel's belief that the Attunga skarn deposits are part of a larger metalliferous system, possibly including a porphyry source. ❋ Unknown (2010)

Mineralisation occurs in garnet-rich calc-silicate skarn with sulphide minerals including chalcopyrite, bornite and molybdenite. ❋ Unknown (2010)

The Bambana target lies four kilometres northwest of the past producing Rosita copper mine, a copper skarn deposit that is estimated to have produced 305 million pounds of copper over the life of the mine ❋ Unknown (2010)

This is evidenced by multiple skarn bodies and silver/lead vein systems occurring in association with a regional magnetic anomaly that measures 2 km in diameter and is coincident with a poorly exposed intrusive body. ❋ Unknown (2010)

This work is planned to include detailed mapping, trenching and sampling at both the Mina Josefina silver-lead zone and the La Española skarn zone with the goal to delineate drill targets. ❋ Unknown (2010)

The mineralization is hosted in fractures, veinlets and veins associated with a northeast-trending sheeted vein structure hosted in calc-silicate (skarn) rocks and spatially related to a felsic intrusion (quartz-feldspar porphyry). ❋ Unknown (2010)
