Press Release: High-grade gold intercepts continue at Rubicon’s F2 Core Zone, Red Lake, Ontario
<<
- 0.54 oz/ton gold over 14.8 feet plus 22.0 oz/ton gold over 1.6 feet
at 4331 to 4580 feet below surface -
- drift to F2 Core Zone reaches halfway point - on schedule to reach
target in October 2010 -
>>VANCOUVER, Aug. 18 /CNW/ – Rubicon Minerals Corporation (RMX:TSX: / RBY:NYSE-AMEX) is pleased to provide an update of the latest diamond drill results at its 100% owned Phoenix Gold Project, located in the heart of the prolific Red Lake Gold District of Ontario. All new drill results are shown in Table 1 and Figures 1 and 2. Emerging gold zone outlines of the F2 Gold System are shown in Figure 3.
Deep drilling in target area 8 confirms gold mineralizing system continues to depth
Recent drilling of deep target area 8 from both underground and surface has returned positive gold results in the southwestern part of the F2 Gold System at depth (Figure 1 and 2). Underground drill hole 305-06 intersected 0.54 oz/ton gold over 14.8 feet (18.6 g/t gold over 4.5 metres), and is part of a wider intercept grading 0.32 oz/ton gold over 29.5 feet (10.9 g/t gold over 9.0 metres) at a vertical depth of 4580 feet (1396 metres) below surface. Surface holes F2-100A and F2-100A-W1, testing target areas 5 and 8 intersected multiple gold zones including a bonanza hit of 22.0 oz/ton gold over 1.6 feet (754.2 g/t gold over 0.5 metres) at a vertical depth of 4331 feet (1320 metres) below surface in drill hole F2-100A and 4.16 oz/t gold over 1.6 feet (142.6 g/t gold over 0.5m) within a broader zone grading 0.27 oz/t gold over 31.5 feet (9.2 g/t gold over 9.6 metres) at a vertical depth of 3563 feet (1086 metres) below surface in drill hole F2-100A-W1 (Table 1 and Figure 2).
These results begin to fill in the deep target areas and demonstrate that the robust F2 Gold System, as documented by over 492,000 feet (150,000 metres) of drilling to date, continues to depth.
Drilling in target area 5 expands the 122-10 Zone to depth
The F2 Gold System is comprised of several zones identified to date: the F2 Core Zone, the Crown Zone, the 102 Zone in the Northern Extension Area, the Hanging Wall Zone, the 122-40 Zone and the 122-10 Zone (Figure 3). Drill hole 122-67 was designed to test approximately 820 feet (250 metres) below the 122-10 Zone (named after the discovery hole announced September 14, 2009 that intersected 0.40 oz/ton gold over 147.3 feet (13.7 g/t gold over 44.9 metres) including a higher grade section of 0.83 oz/t gold over 59.0 feet (28.4 g/t gold over 18.0 metres)). Drill hole 122-67 intersected 0.48 oz/ton gold over 16.7 feet (16.3 g/t gold over 5.1 metres) including 1.16 oz/t gold over 3.3 feet (39.9 g/t gold over 1.0 metres) at a vertical depth of 3087 feet (941 metres) below surface (Table 1 and Figures 1 and 2) and further extends the 122-10 Zone to depth.
Underground drift on the 305 metre level at halfway point – on target to reach F2 Core Zone in October
The 305 metre level drift (1001 feet) is designed to provide access for both definition drilling and bulk sampling of the F2 Core Zone. As of July 31, the drift reached the halfway point and is on schedule to access the F2 Core Zone by October 2010. A new drill station was set-up at the halfway point and three drills are now turning on the 305 metre level. This latest drill station allows for more cost-efficient drilling due to its closer proximity to the gold bearing zones discovered to date in the central F2 Gold System. Upon completion of the drift in October, Rubicon plans to establish a cross drift and up to four drill stations to be used for the definition drilling of the F2 Core Zone.
Rubicon plans to commence in August, 2010 the excavation of a second egress (a second underground exit to surface) from the 305 metre level as this is a Provincial regulatory requirement to permit mining from underground. The Company has also secured an option to purchase a larger hoist than currently on site, to allow for the project’s potential mining capacity to be increased up to 2000 tonnes per day.
Rubicon Minerals Corporation is a well-funded exploration and development company, focused on exploring and developing its high-grade gold discovery at its Phoenix project in Red Lake, Ontario. Rubicon controls over 65,000 acres (100 square miles) of prime exploration ground in the prolific Red Lake gold district of Ontario which hosts Goldcorp’s high-grade, world class Red Lake Mine. Rob McEwen, President and CEO of McEwen Capital and former Chairman and CEO of Goldcorp, owns 21.4% of the issued shares of the Company.
