Colorina project: A second short drill hole has been completed, MC-12-02, and a third drill hole, MC-12-01B, is in progress. This hole was designed to drill through a low-angle thrust fault and on to test an induced polarization anomaly located on the eastern end of Titan 24, Line 3. Similar-type IP anomalies also occur near the eastern end of Titan 24, lines 1 (Virgen de Carmen), 2 (east of Nora zones C/D) and 4 (east Milagro), and may represent an important exploration target going forward.
- Virgen de Carmen project: The second core drill rig is currently drilling east of the old copper/silver mine workings in the area to test for the source and or extension of the near-surface mineralization.
Nora project, target zones A/B: At the Nora project area, two drill holes (DDH-N-11-03 and -04) were completed to test for possible stratigraphically controlled gold mineralization and investigate an IP chargeability anomaly. Based on the mineralization features encountered, two more drill holes (DDH-N-12-05A and -06A/B) were then positioned farther south as a follow-up test of a prospective package of sedimentary rocks peripheral to a prominent thick anhydrite layer encountered in both the first two drill holes. A fourth drill hole (-06A/B) was just recently completed and is currently being logged and sampled.
The Nora area includes four zones (A to D) of mineralized barite veins, with strong gold and copper values (fewer than 0.005 to 17.8 grams per tonne gold, 14 to 25,500 parts per million copper). Bulldozer trenching across these zones disclosed near-surface wide dispersal of anomalous gold values (fewer than 0.005 to 20.7 g/t Au). The geologic concept being drill tested was that the veins zones could have provided feeder systems to possible favourable stratigraphic intervals hosting gold and/or copper-gold sulphide mineralization over a laterally extensive area. Hence, the IP (high) and near-coincident/slightly deeper resistivity (low) anomalies might reflect the presence of this style of mineralization.
DDH-N-11-03 was sited within zone B in part to test the concept and IP anomaly in an area of veining. DDH-N-11-04, though, was located between zones B and A and was thus positioned within an area largely devoid of veins. Interesting concentrations of pyrite with accessory chalcopyrite were noted with veining above and in the vicinity of a thick anhydrite layer in DDH-N-11-03. These features were absent in DDH-N-11-04. This led to DDH-N-12-05A being sited 800 metres to the south within zone A as a stratigraphic test, especially of the anhydrite interval. The latter drill hole intersected thick intervals of strong albite-quartz, quartz-sericite and calc-silicate alteration -- all were strongly pyritized and cut several well-mineralized (copper-gold sulphide) vein structures. Importantly in DDH-N-12-05A, three prominent layers of massive pyrite plus chalcopyrite comprising a five-metre thickness were intersected immediately beneath the footwall of the anhydrite layer between 512 to 517 metres (drilling depths). Significant assay results are shown in the attached table.

The IP/resistivity anomalies across the central part of the Nora project area are caused by strong concentrations of disseminated pyrite comprising the quartz-sericite pyrite halos to the sulphide veins and calc-silicate-replaced stratigraphic intervals within zones B, C and D. DDH-N-11-04 was located between zones B and A and did not intersect strong alteration or appreciable disseminated pyrite and only a few sparse sulphide veinlets. The farthest south drill hole, DDH-N-12-05A, found, within zone A, much more intense alteration and pyritization, stronger pyrite-chalcopyrite veining, and appearance of massive pyrite-chalcopyrite layers in the footwall to the anhydrite layer. These features combine to point to intensity of alteration and mineralization improving in a southward direction.
Further drilling (three holes) to test the prospective anhydrite interval has been recently carried out in an area located west of the Milagro mine; and core processing is in progress.
The orientations of the Nora drill holes were optimum for testing the stratigraphic target idea and geophysical anomalies; however, a different orientation would be required to make complete intersections across (perpendicular to) the strike of the vein zones (that is, zone A). Once all the results are available for DDH-N-12-06A/B, consideration will be given to attempting drilling down across the entire vein swarm.
Over the past several months, there have been considerable delays in receiving assay results from the lab due in large part to high sample volumes from the large number of exploration programs in the region. The lab has assured the company it has taken steps to expand its capacity to meet the high volumes, and the company anticipates the turnaround time should continue to improve over the coming months.
Current drilling at Los Zorros property is exploring for gold and silver at multiple project areas within the company's extensive landholdings that now cover more than 100 square kilometres. This round of drilling is following up exploration results from earlier drilling and is also testing anomalies identified by the Titan-24 geophysical survey, which was completed last year.
Los Zorros landholdings now cover a 15-kilometre strike of the prospective range front/anticline, along which mineralization is exposed in old-time piquenero underground workings, open cuts, trenches, and pits situated in the Colorina, Nora, Virgen del Carmen, Cresta de Gallo and Trueno project areas that are yet to be systematically explored by Samex.
Samex is making steady progress in exploring this large and complex district and continues to develop a clearer understanding of the controls and influences that gave rise to mineralization on the property. Samex is well financed to advance the exploration of its high-priority precious metal projects at Los Zorros, while bringing forward numerous additional targets in the district. The company holds a portion of its working capital in the form of gold and silver bullion.
