Figure 1: Phase IV Drill Campaign Overview
The previously untested Patricia and Daniela targets were also drilled during this campaign. The encouraging intercepts at the Patricia target represent the first significant silver mineralization from these outlying vein trends to the north and east of the principal resource conceptual pits.
Encouraging intercepts at Ely North, located both to the south and north of the current resource, have the potential to add new tonnage to the current
At the Martina trend, the focus was to test the potential for new mineralization. The encouraging results obtained from MNW-DDH-006 and MC-DDH-002 combined extend the mineralization along the Martina trend by almost 100 meters to the North and South.
Significant results from the Phase IV drill campaign:
Margarita Vein Drill Results:
At the Margarita high-grade silver trend, three drill holes for a total of 333 meters successfully extended the mineralized vein by more than 150 meters to the north-west. The system remains open in both directions. The Margarita Vein has similar mineralization to the Julia Vein which hosts most of the current silver resources at
Margarita hole MR-DDH-004 returned 4.85 meters at 720 g/t silver, including a discreet intercept of 0.30 meters at 1,775 g/t silver, exhibiting a strongly banded epithermal vein with fine-grained sulphides and copper oxides.
Figure 2: Margarita Vein Trend Long Section with Interpreted
Hole MR-DDH-005, the northern most hole to date along Margarita, returned values of 2.00 meters at 322 g/t silver and 0.6 meters at 673 g/t silver.
Hole MR-DDH-006, drilled to a vertical depth of 100 meters below surface, returned 3.6 meters at 185 g/t silver, including 0.5 meters at 588 g/t silver, showing that high-grade silver mineralization extends to depth and remains open.
Ely Central Vein Drill Results:
At Ely Central three holes were drilled for a total of 261 meters testing the gaps within the 500-meter-long trend. This newly identified silver-rich vein trend hosts previously reported high-grade drill intercept of 1,110 g/t silver over 5.70 meters (drill hole EC-DDH-005, see news release dated
Figure 3:
Notable intersections from the Ely Central drill holes:
• EC-DDH-011: 11.95m at 124 g/t silver, including 1.8m at 192 g/t silver
• EC-DDH-010: 1.95m at 190 g/t silver, including 0.3m at 553 g/t silver
• EC-DDH-012: 2m at 87 g/t silver, including 0.3m at 182 g/t silver
Figure 4:
Further infill drilling is required to test the remaining gaps along the Ely Trend. This could potentially connect the Ely Central and Ely South conceptual resource pits. Existing gaps are between drill holes EC-DDH-012 and EC-DDH-002 and also in the northern end. The higher-grade intersections of the adjacent southern zone to the Ely North conceptual resource pit may connect to expand the Ely North resource between drill holes VG-183 and EC-DDH-008 and in the southmost part of Ely Central.
Ely North Vein Drill Results:
One drill hole, EN-DDH-006, tested the northern extension of the 200-meter-long anomalous southern end of
This result is very significant as it extends the trend 50 meters to the north and also reduces the gap with the conceptual resource pit at Ely North (gap between EN-DDH-006 and previous drilling VG-186.
A priority geophysical chargeable anomaly located to the north of hole EN-DDH-006 remains untested and may close the gap with another hole located 50 meters north of EN-DDH-006. The northern-most end of the Ely North conceptual resource pit was also extended by EN-DDH-001 and remains open to north.
Martina Vein Drill Results: (Martina NW and Martina Central)
Two new holes were drilled at the Martina vein trend.
• MNW-DDH-006: 4.8m at 91 g/t silver
• MC-DDH-002: 2.9m at 127 g/t silver, including 1.45m at 179.5 g/t silver
Figure 5: Martina Vein Trend Long Section with Interpreted
Martina Central drill hole MC-DDH-002 returned silver intersections and was designed to start testing the gap between the Martina Central and northwest trends. Gaps still remain along the Martina structure with the potential for silver grades to be associated with the notable high chargeability responses. Hole MNW-DDH-006 filled the gap in the Martina NW and extended the mineralization along this 200-meter-long trend.
Patricia and Daniela Vein Drill Results:
One drill hole tested each of these veins which were untested targets hosting the highest-grade surface rock-chip silver samples. The objective of these holes was to test for downdip extensions of the surface expressions. The Patricia drill hole PA-DDH-001 intersected 1.45 meters at 120 g/t silver, including 0.5 meters at 198.5 g/t Silver, and another parallel structure with 2.95 meters at 95.7 g/t silver, including 0.35 meters at 163 g/t silver. These modest drill results did not replicate the extremely high-grade rock chips from near source float blocks samples (over 29,000 g/t silver and 18,800 g/t silver) from surface at Daniela and Patricia (see news release dated
Hole SRE-DDH-005 was drilled at the Santa Rita East breccia structure to test the potential depth continuity of the epithermal quartz-adularia vein intercepted in hole SRE-DDH-003 (5.20 meters at 0.63 g/t gold and 7 g/t silver from 35.30 meters, see news release dated
