Magnetic anomalies are only just that – magnetic anomalies. They are not gold deposits. However, Media Luna appears to be one of those rare cases where a magnetic anomaly points to where the gold is.
TORONTO, ONTARIO–(Marketwired – Sept. 23, 2013) – Torex Gold Resources Inc. (the “Company” or “Torex”) (TSX:TXG)(TXG.WT.A) is pleased to report that results of its new exploration drilling program intercepted high grade Au-Ag-Cu mineralization over significant widths, beyond the recently published Media Luna Inferred Resource. Highlighted intercepts in Media Luna, but outside of the resource area, include 12.96 g/t Au Eq. over 10.8m in borehole NWZML-05 and 10.26 g/t Au Eq. over 6.6m in borehole NWZML-01B. In Media Luna West, significant intercepts include 9.81 g/t Au Eq. over 4.8m in borehole MLW-22 and 4.40 g/t Au Eq. over 14.9m in borehole MLW-03A. In the La Fe area, approximately 2 km northwest of the Media Luna resource area, reconnaissance borehole SS-07 intercepted 3.96 g/t Au Eq. over 6.1m.
In addition, a recent magnetic survey completed over the entire property, suggests a 26% increase in the area of the three magnetic anomalies in the Media Luna Area (498 ha to 630 ha). Interpreted in the ‘new’ magnetic area is a connection between the Media Luna West anomaly and the northwestern ‘lobe’ of the Media Luna anomaly. The same survey reveals several other magnetic anomalies both north and south of the Balsas River, which are currently being evaluated by the exploration team.
Aeromagnetics or ground magnetics can show the underlying structure of the rock due to variations in the abundance of the magnetic minerals magnetite and pyrrhotite. Knowing the structure of the rocks can help geologists identify potential sites for gold deposition. At Media Luna the gold mineralization appears to correlate well with the magnetic anomalism. A magnetite-bearing skarn, which hosts the gold, encases a granodiorite intrusion. Because the skarn is magnetic the most probable sites for gold mineralization can be identified in the aeromagnetic images and drilled. With each success comes more confidence, enabling Torex to add more gold to their inferred resource. Below is an aeromagnetic image showing the magnetic anomalies that Torex is chasing relative to the current Media Luna resource area. A cross-section showing the drillholes intersecting the skarn mineralization at Media Luna is also shown.
Fred Stanford, President & CEO of Torex stated: “The gold potential ‘south of the river’ continues to be very prospective and encouraging. We look forward to drill testing the interpreted magnetic connection between Media Luna West and Media Luna and to understanding the potential that it might offer. Todos Santos, the third magnetic anomaly in the Media Luna Area, also shows significant promise. We are pushing a road down to the first Todos Santos drill platform and anticipate the start of drilling before year end.” He added, “A great deal more work is required to fully understand the nature and overall potential of the entire 29,000 ha of the claim area. The expansion of the footprint of the Media Luna Area magnetic anomalies to 630 ha means that the recently released resource covers only 24% of the interpreted magnetic area. In addition, the resources also occur over an additional 30 ha in an area outside of the main magnetic anomaly. In the Media Luna Area, magnetism can indicate potential mineralization, but a lack of magnetism does not necessarily indicate a lack of mineralization. We look forward to the continuing efforts to fully evaluate the many untested targets, both north and south of the river.”
Highlights of exploration drilling at Media Luna
|True thickness of the mineralized zone is unknown and is reported as drill hole length|
|The gold equivalent grade, including copper and silver values, is based on 100% metal recoveries. The gold grade equivalent calculation used is as follows: Au g/t (EQ) = Au g/t + (Cu grade x ((Cu price per lb/Au price per oz) x 0.06857 lbs per oz x 10000 g per%)) + (Ag grade x (Ag price per oz/Au price per oz)). The metal prices used were: Gold – $1495/oz, Copper – $3.39/lb, Silver – $26.45/oz|

A ZTEM and magnetic survey covering 1,620 line-kilometers was completed over the Torex concession. Initial results from the magnetic survey reveal notably different shapes for the main magnetic anomalies in the Media Luna Area (see Figure 2). Of particular note is an expansion of the main Media Luna anomaly to the northeast and the appearance of a connection between the Media Luna West anomaly and the NW extension of Media Luna. The Todos Santos anomaly also has a slightly different shape. The cause of the differences between the new magnetic and the previous (year 2000) magnetic data is not known. The changes in the shapes may result from surveying using a different line direction, lower magnetic sensor height and better line control using a helicopter. The ZTEM data highlights resistivity contrast within the local rock packages and will be particularly useful to define rock contacts and vertical structures that may have been conduits for mineralizing fluids. Both the ZTEM and magnetic data are being used to create 3D inversion models that will support detailed targeting within prospective areas.
Exploration on the magnetic anomaly lobe that extends NW from the Media Luna Inferred Resource area is aimed at completing wide-spaced drill testing of the magnetic anomaly. New roads are under construction toward the north of the Media Luna Resource Area to access this topographically challenging target. Mineralization encountered in drilling to date in the NW area is similar in character to Media Luna.
Ten drill holes have been completed at Media Luna West. The drilling defines an area with current dimensions of approximately 500m x 700m that contains strong Au-Ag-Cu mineralization associated with magnetite-pyrrhotite-bearing exoskarn alteration. The mineralization is similar in nature to Media Luna. The large zone of magnetic anomalism between Media Luna West and the NW zone has yet to be drill-tested (see Figures 2 and 3).
Four exploration drill holes were also completed in the La Fe target area, located approximately 2 km northwest of the Media Luna resource area. These holes targeted the limestone-granodiorite contact zone in areas of smaller magnetic anomalies. Three of the four wide-spaced holes encountered significant Au-Ag-Cu mineralization associated with magnetite-pyrhotite-bearing exoskarn. The fourth hole intersected a post-mineral intrusive dike at the contact.
The focus of ongoing exploration will be to continue wide-spaced drilling at Media Luna West and NW Media Luna and to test the zone of magnetism that connects these 2 areas. In addition, reconnaissance drilling will test Todos Santos and other magnetic anomalies in the area.
The potential quantity and grade of the exploration targets are conceptual in nature and there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the determination of a mineral resource.
