HIGHLIGHTS• Drilling at Tokop Gold Project in Nevada, USA, commenced on 6
August 2013.
• Three holes already completed with a fourth currently in progress.
• Two further holes planned (for a total of 6).
• Geology observed in drill holes is consistent with mapped surface geology.
• Quartz veining is best developed within the intrusion.
• Assay results are expected in about three weeks.
Australian exploration company, Global Geoscience Ltd ("Global") (ASX: GSC), today announced the maiden drilling program at its Tokop Gold Project in Nevada, USA, was well advanced.
Tokop, and the nearby Excelsior Gold Project, are two tenements the Company holds in southern Nevada that have only recently been recognised as Intrusion Related Gold (IRG) systems.
No systematic surface exploration had been undertaken at either project prior to Global's activities.
The maiden drilling program at Tokop consists of wide-spaced Reverse Circulation (RC) holes over a strike length of about one kilometre as an initial test of the 2000m by 750m zone of gold mineralisation
Gold mineralisation at Tokop is associated with sheeted and stockworked quartz veins developed within a multiphase granite intrusion. Large parts of the intrusion are interpreted to lie beneath the enclosing limestone. Where the intrusion is exposed at surface it displays quartz-sericite alteration, quartz veining and gold mineralisation.
"Our maiden drilling program at Tokop is progressing well, and the alteration and quartz veining we are observing in the drill chips is consistent with what we see on the surface and in the trenches," Global Geoscience Managing Director, Mr Bernard Rowe, said today.

The Tokop Gold Project is an Intrusion Related Gold (IRG) system with similarities to other IRG
deposits including Donlin Creek (31Moz), Fort Knox (9Moz) and Dublin Gulch (2Moz) in the Tintina Gold Province of Alaska/Yukon and Bald Mountain (8Moz) in Nevada. The Project is located in southern Nevada, about 300km from Reno and 200km from Las Vegas. Access is via Highway 95 which passes within 15km of the property.
Gold mineralisation occurs within and immediately adjacent to a multi-phase Jurassic granite intrusion. Gold is associated with sheeted and stockworked quartz veining and quartz-sericite alteration.
Figure 1. The main target at Tokop is defined by a 2km x 1km arsenic soil anomaly. Within the arsenic halo, high levels of Au, Bi, Mo and W cluster within and around the margins of three exposed intrusions. Intervals with gold grade shown are for rock channel samples collected from trenches and road cuts.
Trenching and channel sampling has been undertaken at three locations over about 1km of strike. Results from the trenching include:
