Xtra-Gold Provides Exploration Update on Its Expanding Zone 5 Gold Corridor Where Seven Shear Zones Have Been Identified to Date
04.03.2013 | GlobeNewswire
TORONTO, March 4, 2013 (GLOBE NEWSWIRE) -- Xtra-Gold Resources Corp. ("Xtra-Gold" or the "Company") (TSX:XTG) (OTCQB:XTGRF) is very pleased to announce channel sampling results from a new exposure of the Main Shear, in addition to initial channel sample results from 6 recently identified shear zones forming part of the Zone 5 Gold Corridor, on the Company's wholly-owned Kibi Gold Project, located in the Kibi – Winneba greenstone belt (the "Kibi Gold Belt"), in Ghana, West Africa. Highlights of the channel sampling results and Zone 5 Gold Corridor expansion work reported today include:- New gold shoot discovered along Main Shear approximately 350 m southwest of discovery high-grade gold shoot; with shear consisting of braided (anastomosing) structure attaining 13 m in width and encompassing 4 sinuous mylonitic branches ranging from approximately 0.4 m to 4 m in width. Highlights from channel sampling of mylonitic shear branches include: 2.5 m grading 4.71 g/t gold and 3.9 m grading 5.9 g/t gold in channel sample strings #KBCS080-7 and #KBCS080-9, respectively (SE Branch); 1.1 m grading 14.77 g/t gold, including 26.1 g/t gold over 0.5 m in #KBCS080-18 (Central Branch); and 1.5 m grading 10.47 g/t gold, including 20.4 g/t gold over 0.5 m and 1.6 m grading 11.14 g/t gold, including 17.8 g/t gold over 0.8 m in strings #KBCS080-2 and #KBCS080-5, respectively (NW Branch).
- Geological mapping/sampling to date indicates that the Zone 5 Gold Corridor corresponds to a minimum 325 m wide braided shear zone system encompassing at least 7 auriferous shear zones; with the Main Shear traced to date over an approximately 475 m strike length. The auriferous shear zone system is spatially associated with an approximately 1.8 km long by 300 m to 800 m wide, NE-trending, anomalous gold-in-soil trend.
- Extensive arrays of mineralized low-angle extensional quartz-tourmaline veins spatially associated with all 7 shear zones; greatly enhancing the bulk mining potential of the Zone 5 Gold Corridor.
The present exploration results correspond to an ongoing mechanized outcrop stripping / trenching transect designed to test the southwestern strike extension of the Main Shear and define the full width extent of the NE-trending Zone 5 Gold Corridor. Approximately 65% (325 m) of the planned 500 m long, NW-trending transect located approximately 350 m southwest of the discovery high-grade gold shoot has been completed to date; with the transect positioning based on favorable topography in combination with shallow overburden cover, previously identified gold-bearing structures, and priority geophysical targets.
Geological mapping and grab / channel sampling of the bedrock exposed to date along the transect has identified 7 auriferous structures distributed over an approximately 325 m width of the Zone 5 structural corridor; including the apparent southwestern strike extension of the Main Shear. The structures consist of sinuous anastomosing shear zones ranging from approximately 1 m to 13 m in width and containing irregular steeply dipping veins, stringers, and lenses of quartz plus/minus iron carbonate and tourmaline. Extensive arrays of mineralized low-angle extensional veins are spatially associated with the controlling vertical shear veining.
The apparent southwestern strike extension of the Main Shear was exposed over an approximately 55 m strike length within the southeastern portion of the outcrop stripping / trenching transect, approximately 350 m southwest of the discovery high-grade gold shoot. At this locality, the Main Shear consists of a braided (anastomosing) structure attaining 13 m in width and encompassing 4 sinuous high shear strain branches ranging from approximately 0.4 m to 4 m in width; bounding relatively less deformed/altered rock lozenges. The NE-trending, steeply SE dipping, pinch and swell high strain branches range from silicified / carbonatized mylonitic rock containing irregular quartz-tourmaline veining / lenses to sericite-iron carbonate-pyrite schist hosting parallel quartz veining. Arrays of mineralized low-angle extensional quartz-tourmaline veins cross-cut the mylonitic zones and visually extend up to 10 m into the wall rock.
A total of 152 bedrock saw-cut channel samples totaling 86 m were collected over an approximately 40 m strike distance of the new Main Shear exposure, including 52 vertical or steeply inclined channel samples (28 m) collected on outcrop ledge faces to test low-angle extensional veining arrays. In aggregate these samples form 51 composite channel strings ranging from 0.20 m to 7.6 m in length, with individual channel samples averaging approximately 0.55 m in length. Of the 152 channel samples collected: 5 (3%) yielded less than 0.01 g/t gold; 28 (19%) returned gold values from 0.01 g/t to 0.1 g/t; 58 (38%) between 0.1 g/t and 1.0 g/t gold; 18 (12%) between 1 g/t and 2 g/t gold; 23 (15%) between 2 g/t and 5 g/t gold; 14 (9%) between 5 g/t and 10 g/t gold; 4 (2.5%) between 10 g/t and 20 g/t gold; and 2 samples (1.5%) returned values over 20 g/t gold (26.1 g/t maximum).
Highlights from a series of channel samples collected from the respective mylonitic branches over an approximately 20 m strike length include mineralized intercepts of: 2.5 m grading 4.71 g/t gold and 3.9 m grading 5.9 g/t gold in channel sample strings #KBCS080-7 and #KBCS080-9, respectively (SE Branch); 1.1 m grading 14.77 g/t gold, including 26.1 g/t gold over 0.5 m in #KBCS080-18 (Central Branch); 1.5 m grading 10.47 g/t gold, including 20.4 g/t gold over 0.5 m and 1.6 m grading 11.14 g/t gold, including 17.8 g/t gold over 0.8 m in strings #KBCS080-2 and #KBCS080-5, respectively (NW Branch); and 0.4 m grading 2.08 g/t gold in sample string #KBCS080-21(NW-2 Branch). The highly accidented bedrock surface, including overburden filled crevices, is typically non-conducive to continuous channel sampling across the width of the structure; with the less deformed/altered rock between the shear branches typically being recessively weathering. Local sampling of the inter-shear branch rock where possible yielded gold values in the 0.1 g/t to 1.5 g/t range. See Table 1 for the full listing of significant mineralized intercepts from the respective mylonitic zones and intercepts yielded by vertical channel sampling targeting sub-horizontal extensional veining.

Notes:
Due to irregular bedrock surface the reported intercepts are sample intersection lengths irrespective of mineralization topography and may not represent true width of mineralization.
Channel String ID with "V" corresponds to vertical or steeply inclined channel sampling targeting low-angle extensional veining.
A total of 428 bedrock saw-cut channel samples totaling 253 m were collected from the remaining 6 shear zones emplaced within the Zone 5 Gold Corridor, including 25 vertical or steeply inclined channel samples (14.5 m) collected on outcrop ledge faces to test low-angle extensional veining. In aggregate these samples form 123 composite channel strings ranging from 0.20 m to 25 m in length, with individual channel samples averaging approximately 0.60 m in length. Sampling to date ranges from widespread scout channel sampling to detail channel sampling on 3 structures, respectively. Of the 428 channel samples collected: 12 (3%) yielded less than 0.01 g/t gold; 205 (48%) returned gold values from 0.01 g/t to 0.1 g/t; 159 (37%) between 0.1 g/t and 1.0 g/t gold; 18 (4%) between 1 g/t and 2 g/t gold; 23 (5%) between 2 g/t and 5 g/t gold; 10 (2%) between 5 g/t and 10 g/t gold; and 1 sample returned a maximum value of 11.5 g/t gold.
The 6 parallel shear zones are characterized by widespread anomalous gold values in the 0.1 g/t to 1.0 g/t range (37% of samples) with localized higher grade values attaining 11.5 g/t gold. Channel sampling highlights on the respective structures include mineralized intercepts of: 1.2 m grading 5.93 g/t gold and 1 m grading 6.39 g/t gold in channel sample strings #KBCS035 and #KBCS045, respectively (L7675 Shear); 0.8 m grading 8.83 g/t gold in sample string #KBCS078-2 (L7600W Shear); 0.5 m grading 9.76 g/t gold in #KBCS077-1 (Old Pit Shear); 1.1 m grading 3.83 g/t gold, including 6 g/t gold over 0.6 m in #KBCS076-31 (L7600E Shear); and 0.8 m grading 2.58 g/t gold in sample string #KBCS076-50 (Main-East Shear). See Table 2 for the full listing of significant mineralized intercepts from these 6 shear zones.
Highlights of vertical channel sampling across low-angle extensional veining arrays spatially associated with the controlling vertical shear veining include: 1.1 m grading 3.51 g/t gold and 0.8 m grading 6.85 g/t gold in sample strings #KBCS077-V1 and #KBCS077-V2, respectively (Old Pit Shear); 0.4 m grading 2.45 g/t gold in #KBCS079-V1 (L7600W Shear); and 1.3 m grading 4.15 g/t gold in string #TCK008-V-47.7 (L7700 Shear). In the case of the L7700 shear a set of 3 vertical channel sample strings returned considerably higher gold values ranging from 1.17 g/t to 4.15 g/t over 0.7 m to 1.3 m lengths; than the 0.27 g/t gold over 2 m yielded by the vertical shear vein.
In addition to channel sampling, a total of 137 rock grab samples were also collected from the 7 shear zones as part of first pass sampling to guide subsequent channel sampling. Of the 137 quartz veining and silica-iron carbonate-pyrite altered wall rock grab samples collected: 26 (19%) yielded less than 0.01 g/t gold; 40 (29%) returned gold values from 0.01 g/t to 0.1 g/t; 24 (18%) between 0.1 g/t and 1.0 g/t gold; 26 (19%) between 1 g/t and 5 g/t gold; 14 (10%) between 5 g/t and 10 g/t gold; and 7 (5%) samples returned gold values between 10 g/t and 19.85 g/t.

Preliminary geological observation indicate that the Zone 5 Gold Corridor corresponds to a minimum 325 m wide, multi-structure, braided shear zone system emplaced along a quartz feldspar porphyry ("QFP") body; with the Main Shear traced to date over an approximately 475 m strike length. The auriferous shear zone system is spatially associated with an approximately 1.8 km long by 300 m to 800 m wide, NE-trending, anomalous gold-in-soil trend centered on a moderate magnetic / high radiometric airborne geophysical signature appearing to delineate the QFP body.
Outcrop stripping / trenching continues on the planned 500 m long transect to determine the full width extent of the Zone 5 Gold Corridor; as well as detail geological mapping and channel sampling of the auriferous shears identified to date. Infill soil geochemical sampling and prospecting is also in progress on newly established detail (100 m) grid lines covering the 1.8 km long Zone 5 gold-in-soil anomaly. A 30 km pole-dipole induced polarization (IP) survey covering a 2.2 km by 1.0 km – 1.5 km grid at 100 m spacing was completed by Sagax Afrique S.A. in February 2013; with the final results and interpretation still pending.
