TORONTO, Jan. 13 /CNW/ - Mantis Mineral Corp. ("Mantis" - CNSX "MYN") is pleased to announce that as part of its on-going compilation and re-interpretation of the Orphan Gold Mine geology, a multi-sub-parallel complex vein system is emerging. This effectively means that the Orphan vein originally thought to be one vein, branches and splits into several veins producing a much wider zone of potential gold mineralization.
The following drill holes add significantly to previous reported gold potential of the Orphan gold system. Between 1986 and 1987 Canadian Gold Resources (CGR) completed 3,311-meters of drilling in 25-holes. Below are some of the holes that have contributed to the current interpretation of the Orphan vein system.
Hole CGR86-5, section 29925E, was collared 66-meters west of the shaft. In this hole, two intersections, one at vertical depth of 48-meters assayed 8.76 gpt along a 1.07-meter interval and the second intersection at a 55-meter vertical depth yielded 7.93 gpt along a 2.13-meter cored interval. The deeper intercept correlates with the 'Main Vein' while the shallow intercept is a splay of it.
Hole CGR86-14, section 29975E, collared 35.8-meters west of the shaft, intersected the 'Main Vein' at 95-meter vertical depth and returned an assay of 2.67 gpt along 1.2-meters. On the same section, CGR86-15 intersected the main vein at a vertical depth of 149-meters and yielded an assay of 3.09 gpt along 1.5-meters. The 'Main Vein' was intersected again at a vertical depth of 208-meters in hole CGR86-16 and yielded 3.79 gpt along 4.88-meters. Along this section, 28-meters north of these 'Main Vein' intersections a quartz vein sub-parallel to the 'Main Vein' has become apparent. This 'New Vein' intersected in 4-holes returned low gold values but contained up to 10% sulphides in the form of pyrite and chalcopyrite to a vertical depth of 74.8-meters. Importantly, this vein can be traced 50-meters east to section 30025E, where gold values significantly increase.
Hole CGR86-13, section 30000E, intersected the 'New Vein' at 74.5-meter vertical depth and yielded an assay of 12.8 gpt gold along 1.52-meters. The next intersection of this vein occurred at a 162.6-meter vertical depth in hole OMV08-1, drilled by Mantis in 2008. A 3-meter intersected zone containing several quartz veins one of which contained visible gold, chalcopyrite, sphalerite and molybdenite mineralization, returned a gold value of 51.7 gpt along a 0.18-meter sample length.
On section 30025E this 'New Vein' was intersected again at vertical depth of 129-meters. A wide zone of 9.94-meters contained intermittent quartz veining with pyrite and chalcopyrite, low gold values were encountered.
The results of this on-going compilation and detailing of drill hole intersections are very significant as they reflect the multi-vein nature of the Orphan Mine geology and could have significant implications for the tonnage potential of the system. Furthermore, since the 250-level (vertical depth of 76-meters) was the deepest level of the 'Main Vein' development, several of the above intercepts occur substantially deeper, illustrating the down dip continuity of the Orphan gold system.
The Orphan Main Vein was accessed by a 262-foot (80-meter) deep shaft and ore was mined by drifting on the 150-foot (45-meter) level for 61.6-meters and on the 250-foot (76-meter) level for 107.3-meters. Historical records indicate that minimal mining was done in two very small stopes (an underground working where ore is removed by upward progressions in lateral sections in the plane of the vein), presumably leaving behind substantial ore. Historical data has delineated target blocks for potential tonnage calculations. The projection is to the 97.5-meter level. As is illustrated from historical reports, down dip the vein is open to hosting significant gold mineralization.
Mantis' 2008 drill program confirmed the high-grade nature of the Orphan Main vein below the 75-meter level of the mine. There is no reason to doubt given the above results that the mine's average grade of 0.689 ounces per ton (23.62 gpt) gold should not stand up at greater depths. A second phase program is planned to test the high grade main vein at vertical depths to 350-meters and along the 225-meter strike length hosting 330,750-tonnes of potentially gold bearing vein material as well as test for additional veins as indicated from newly compiled data.
Robin Ross, CEO, commented, "The re-interpretation of both Mantis' drill data and historical drill data conducted in the late 1980's has significantly increased the potential of the Orphan Mine. What was once considered a single vein appears to be emerging into a complex vein system which bodes well for increasing the tonnage and hence contained gold of the Orphan Mine.
Should the grade hold up, the 330,750 tonnes mentioned above for the 'Main Vein' have the potential to host a resource of 227,800 ounces of gold. Conceivably a multi-vein high grade gold system should increase these numbers substantially. Hence, the reason for our excitement".
Geologically, the former Orphan Gold Mine is situated in the Onaman-Tashota greenstone belt of the Wabigoon sub province of the Archean superior province. Traditionally this belt was referred to as the Beardmore-Geraldton greenstone belt/gold camp. Gold production from this belt has exceeded 4.1-million ounces from 19-mines. The Orphan Gold Mine, also known as the Dik Dik Mine, is included as one of the past producers of this belt. Mining operations were suspended due to the economics of the time. The mine was developed on two levels, the 45-meter level and the 76-meter level which were accessed by an 80-meter deep shaft. Lateral workings, crosscuts and drifts totaled 202-meters.
