'It's exciting to see the Magdalena target significantly expand after just 15 days of field work. Mineralization is present across horizontal and vertical extents with more than 150 m in vertical exposure and two levels of historical underground workings. Additionally, we are seeing anomalies that are consistent with an intrusive related system and the mineralization remains open in all directions, making this area a strong exploration priority of the 13 targets in the Hurricane district.'
Magdalena Epithermal Structures:
Silver-rich epithermal vein - fault structures have been mapped over an area of approximately 2 km by 2 km with approximately 200 m of vertical exposure. Recent field work consisted of mapping, rock and channel sampling with the goal of extending the strike length of the mineralized structures and getting a better understanding of the grade distribution through infill channel sampling of previously sampled veins (Figures 1 - 2 & Tables 1 - 2).
There are two primary mineralized structures, each greater than 1 km in length, as well as numerous splays and smaller structures in the Magdalena target area (Figure 1). The primary mineralized structures and splays have a combined strike length greater than 4 km and an average width of 1 m - 2 m with local vein widths up to 7 m wide. All mineralized structures remain open along strike and with nearly 60% of the target area under cover there is significant potential to discover extensions of and/or additional mineralized structures.
The mineralized structures were exploited historically via numerous underground mine workings and both recent and historic sampling of these mine dumps reveal significant high-grade silver and copper values (see Table 2 and
Individual channel and rock samples reported elevated tungsten and anomalous rhenium and scandium values that are consistent with an intrusive related mineralized system. Of the 48 rock samples and 44 channel samples, 11% returned tungsten values above 0.1%, with one sample reporting 0.9% W. In addition, dioritic porphyry dykes have been mapped on surface that may be related to elevated tungsten values.
The next phase of exploration at Magdalena will focus on additional field work that includes soil sampling, mapping, trenching and a magnetics IP geophysical survey to evaluate the potential of these structures and the possible magmatic source.
About Tier One
Channel Sampling:
Analytical samples were taken from each 0.1 m - 2.15-m interval of channel floor resulting in approximately 2-4 kg of rock chips material per sample. Collected samples were sent to
Rock Sampling:
Approximately 2-3 kg of material was collected for analysis and sent to
