ABOUT THE COMPANY
Great Basin Gold Limited is an international mining company with two emerging mines in the world's richest gold regions: the Hollister Mine on the Carlin Trend in Nevada and the Burnstone Mine in the Witwatersrand Basin, South Africa. These assets, combined with exploration activities in Tanzania and Mozambique, make Great Basin Gold an exceptionally well positioned investment opportunity.
Burnstone Mine is the first greenfield operation to come online in the Witwatersrand Basin in 30 years, commencing production at a time of record high gold prices and increasing demand. The Hollister Property presents one of the highest-grade deposits entering production today, with prolific potential to increase resources through further exploration of the surrounding area. Lead by a multidisciplinary team of respected industry veterans, Great Basin Gold is poised to transition into a significant commercial producer with excellent growth possibilities.
Great Basin Gold Limited is an international mining company engaged in exploration, development and operation of high-quality gold properties, all while building shareholder value and sustainable communities. The company is currently focused on its two emerging flagship mines in the world's richest gold-producing regions, the Hollister gold mine and associated operations located on the Carlin Trend in Nevada, USA and the Burnstone gold mine located in the Witwatersrand Basin goldfield of South Africa. Together, these operations comprise a total resource base of 23.4M Au oz and 7.3M Au oz reserves.
Great Basin Gold is evolving into a leading mid-tier gold producer through a well-defined strategy of:
- developing gold projects and assets into high margin mining units;
continuing to increase our reserve and resource base through exploration; and
acquiring companies and assets suited to expanding our business.
Great Basin Gold also has prospective exploration projects in both Mozambique and Tanzania.

Great Basin Gold is continuing to increase its resource base through focused exploration programs. Over and above continued activities at the Hollister and Burnstone properties, greenfields exploration is also being undertaken in Tanzania and Mozambique.
The Witwatersrand Basin deposits, such as that found on the Burnstone Property, generally represent gold concentrations, called placer deposits (or "reefs", in local mining terminology), hosted within coarse-grained sediments (conglomerates) deposited in braided stream channels on broad river plains. Economic gold concentrations commonly extend for several km down the dip, and for up to 50 km (30 mi) along strike of the sedimentary rock units. Gold occurs as detrital grains in nugget-like shapes and secondary (re-crystallized) grains, ranging in size between 0.005 and 0.5 mm diameter.
The Witwatersrand Basin has been affected by several structural events. Many studies now differentiate between deformation that was taking place during deposition of the Witwatersrand sediments and subsequent deformation. Deformation that occurred during the deposition of the sediments played a key role in the distribution and thickness of the host rocks as well as the occurrence of the gold-bearing reefs. Later faulting and buckling of the sequence determined which parts of the basin remained buried, and the depths to mineable horizons.
The South Rand area is located in the north eastern part of the Witwatersrand Basin. In the South Rand, the Witwatersrand sequence is thinner than in other parts of the Basin. The West Rand Group, comprising about 1,500 m (4,920 ft) of alternating quartz arenite and shale units, unconformably overlies the Archaean granite-greenstone basement rocks. The overlying Central Rand Group strata are approximately 900 m (2,950 ft) thick and include the Kimberley Reef horizon, which is the main gold-bearing unit on the Burnstone Property. The Johannesburg Subgroup, including the Bird amygdaloidal lava and the Kimberley shale, is about 300 m (985 ft) thick. The Turffontein Subgroup is approximately 600 m (1,970 ft) thick and is made up of a sequence of quartz arenites and conglomerates that correlate with the Elsburg Formation.
An 18-km (11-mi) long northwest-southeast gold trend has been outlined on the Burnstone Property that appears to be associated with a large, ancient, braided channel system extending over the property. Drilling has also shown that two northwest-southeast trending sub-parallel faults, spaced four km apart, have uplifted the central portion of the gold corridor. As a result, a substantial portion of the gold-bearing horizon along the main deposit trend lies between 250 and 750 m (820-2,640 ft) in depth, which is relatively shallow for Witwatersrand gold deposits. The average thickness of the reef is 35 cm.
Nevada Operations Geology
GeologyThe Hollister Property is located at the intersection of the Carlin Trend and the Northern Nevada Rift. The Carlin trend is a northwest trending, 50-mile long metallogenic corridor, which hosts significant opencast and underground operations that have produced in excess of 70 million ounces of gold. Carlin Trend-type mineralization is 38-43 Myrs (Eocene) in age. The Northern Nevada Rift is a north - northwest trending structural feature made up of bimodal volcanic rocks that host Miocene-aged (13-15 Myr) low sulphur-type epithermal gold deposits such as Midas, Mule Canyon, Buckskin National and Hollister. The Paleozoic stratigraphy and Eocene magmatic pulse that is critical to the development of Carlin-type deposits to the southwest are in evidence at Hollister, as are the Miocene mineralizing events. The Hollister stratigraphic section includes Ordovician sedimentary rocks intruded by mid-Eocene plutons and unconformably overlain by a veneer of Miocene volcanic and volcano-sedimentary rocks. Devonian sedimentary rocks have been intersected at a depth below the Ordovician sediments under the Roberts Mountain Thrust.
Epithermal gold mineralization at the Hollister Property occurred in the early Miocene (15.1 Myr) and is directly related to right - lateral wrench tectonics associated with the Northern Nevada Rift, where it over-prints the Carlin Trend. The Hollister Property hosts a low-sulfidation Au-Ag epithermal system characterized by banded quartz veins with electrum, native gold and silver selenides. To date over 40 mineralized veins have been modeled in the main Clementine-Gwenivere vein systems. The veins are narrow (1-3 feet wide), and commonly display colliform banding, brecciation and silicification features indicative of multiple pulses of fluid movement. The low-sulphur epithermal vein systems form as part of a geothermal system around the interface of hot volcanic derived hydrothermal fluids and cold meteoric water influx. Similar active systems such as Yellowstone National Park (Wyoming) and the Taupo Volcanic Zone (New Zealand) demonstrate many of the features observed at Hollister.
Although mineral resources and reserves are delineated on the epithermal vein system hosted in Ordovician metasedimentary host rocks, continued exploration of the orebody has delineated zones of disseminated gold mineralization in the overlying Tertiary volcanic, within which restricted structures host zones up to 100 oz per ton Au. These super high grade Blanket Zones are being accessed and developed as a separate ore source, and have to date have been tested metallurgically at a separate whole ore roasting facility.
Some of the primary geological elements of the sediment-hosted gold deposits of the Carlin Trend are present at the Hollister Property, including Eocene intrusive rocks and lower-plate carbonate rocks. The Hatter stock (a grandioritic intrusive) at the Hollister Property has been dated at 39 Ma and is similar to 39 Ma biotite-feldspar porphyry dikes occurring in the Goldstrike area 5 miles SE in the Carlin trend. The main pulse of gold mineralization on the Carlin Trend is dated at about 38 Ma and commonly thought to be associated with late-Eocene magmatism.
