Goldrush Begins Exploration on Potential Extensions of Ronguen Gold Deposit and on Proximal Targets
![Goldrush Begins Exploration on Potential Extensions of Ronguen Gold Deposit and on Proximal Targets](https://www.minenportal.de/media/goldseiten-news.jpg)
The four phased program is planned to include:
1.up to 500 metres of trenching on the South Zone;
2.four pits on the northern magnetic anomaly, a geophysically identified target which is located subparallel to and 300 to 400 metres north of the Main Zone;
3.up to 1,000 metres of reverse circulation ("RC") drilling on the North Zone, an east-west splay of the Main Zone; and
4.up to 1,000 metres of RC drilling on additional targets identified from the above activities.
The South Zone trenching began November 20 and is planned to be completed by the end of the first week of December. The program of pitting on the north magnetic anomaly and the first phase RC drilling will be completed by mid December. Following a scheduled break to allow for the receipt of assays and interpretation of the data, drilling is scheduled to resume on January 14.
Len Brownlie, President and CEO of Goldrush, noted: "We are very pleased to be able to resume exploration at and adjacent to our Ronguen gold deposit. We are in part taking advantage of recent three dimensional modelling of our older gradient induced polarization data, which has provided four resistivity anomalies bracketing and coincident with the Ronguen mineralization. Given the current market conditions, the competition for drill rigs and delays at assay labs have diminished substantially, and we look forward to the timely receipt of assays and the efficient utilization of resources to demonstrate the ample expansion potential of the Ronguen gold deposit."
The South Zone Extension
As previously announced (Goldrush News Release # 6-2012; February 28, 2012), South Zone diamond drill hole KGRC11-036 spotted on section 530E intersected 6.92 g/t Au over 8.9 metres, including 12.8 g/t Au over 1.2 metres and 16.3 g/t Au over 1.0 metres. The South Zone is an interpreted subparallel structure in the hanging wall of the Main Zone of the Ronguen deposit. Hole KGRC11-036 is the most southerly and deepest hole drilled on the South Zone and was designed to test the down dip potential of the gold mineralization encountered in RC hole KGRR-130 (3.62 g/t Au over 6 metres at a depth of 40.1 metres) and hole KGRR-152 (1.70 g/t Au over 7 metres at a depth of 32.4 metres). On Section 530E, gold mineralization in hole -036 is associated with disseminated pyrite (5 - 10%) and arsenopyrite (1%) in heavily silica flooded and altered diorite. This style of mineralization had not been recognized previously at Ronguen, and represents an additional attractive target for future exploration.
The recent three dimensional modelling of existing gradient array resistivity data has identified a potential new strike direction of the South Zone. Previous exploration of the South Zone had focussed on an extrapolated N070 degree (east northeast) trend which was parallel to the Main Zone, and on which drilling did not intersect significant mineralization. The geophysical model indicates that the linear resistivity anomaly (now interpreted to represent the strike direction of the South Zone) trends at an angle closer to N095, a divergence from the Main Zone trend. The resistivity anomaly follows a sediment filled valley which extends over a distance of two kilometres to where an orpailleur site is located, and is open beyond the end of the survey. The type and depth of the colluvial-alluvial sediment filling the bottom of the valley may have been sufficient to mask evidence of gold mineralization from previous soil sampling of the area.
Evidence of mineralization beneath the valley fill has been found in previous, shallow rotary air blast drilling: hole KGRB10-245 intersected 0.39 g/t Au over 4 metres (from 14 to 18 metres), and hole KGRB10-242 intersected 0.13 g/t Au over 2 metres (from 18 to 20 metres) and 0.11 g/t Au over 2 metres (from 24 to 26 metres). These shallow RAB holes were part of a drill fence located approximately 650 metres east of the currently defined South Zone mineralization. Farther along the same trend, the small, well-established artisanal mining site is located on the side of a hill, approximately two kilometres from the South Zone. Based on the accumulated information and on the new modelling of the induced polarization resistivity survey, Goldrush has initiated a program of trenching to be followed by RC drilling to test positive results along strike and initially to shallow depths on this trend.
The Northern Magnetic Anomaly
Approximately 300 to 400 metres north of the western end of the Main Zone is located a sharp magnetic contact (the northern magnetic anomaly - "NMA") in an area of soil cover, no outcrop and no drilling. The magnetics is interpreted to represent a fault contact whereby sediments to the south have been thrust over gabbro (or mafic volcanics) to the north, a geologically and structurally similar setting to that hosting the mineralization at the Main Zone. Additionally, there is a similar orientation, a possible flexure which is a structural feature of the Main Zone, and a gradient array induced polarization resistivity anomaly. Positive results to the pitting program would present an important new target for exploration at Ronguen.
The North Zone
The North Zone is an interpreted east-west splay of the Main Zone that has been identified over a distance of 260 metres in previous drilling and trenching programs from section 1060E to section 900E of Grid 1 (the eastern grid). West of section 900E, the zone has not been drilled in the oxide profile. Intersections of this zone within this portion of the grid include 2.52 g/t Au over 7 metres in hole RC-171 and 1.15 g/t Au over 12 metres in hole RC-170 on section 1037.5E, and 2.60 g/t Au over 12 metres in hole RC-129 on section 1015E. The potential strike extension of this zone in the oxidized layer is estimated to be up to 600 metres. The first phase RC drilling program will test the continuity and oxide potential of this zone within a previously undrilled portion of the northern margin of the Ronguen deposit.

Goldrush and Burkina Faso
Goldrush has recently expanded and upgraded its resource at the Ronguen gold deposit in central Burkina Faso, providing an asset which is oxidized and amenable to low cost heap leach processing. Ronguen is located in the well endowed Boromo Greenstone Belt. The Boromo Belt contains a near-surface global estimated resource in excess of 13 million ounces of gold in seven of 18 deposits enumerated in the country.
Burkina Faso is a politically and economically stable West African democracy that relies on mining and farming as its primary sources of foreign exchange. The country has seen gold mining flourish, with six new mines coming to production since 2007, vaulting Burkina into the position of fourth largest gold producer in Africa in 2012, and the third largest site for gold exploration on the continent. High River Gold Mines Ltd.[/wp]'s Bissa mine, located just eight kilometres from Goldrush's Ronguen gold deposit, is scheduled to begin commercial production by H1-2013 and will become the seventh active commercial gold mine in Burkina Faso.
