Aurvista Gold drills nine m of 4.53 g/t Au at Douay
AURVISTA GOLD Corp. has released final drill results from the recently completed 2017 spring-sum mer drill program. The drill program totalled 23,965 metres across 59 drill holes. Forty of the 59 completed drill holes focused on the four-kilometre-long porphyry trend, extension targets and multiple zones of mineralization parallel to the core porphyry system. Included in the assays reported today are 13 new drill holes (5,192 metres) in the central segment of the porphyry system (Porphyry zone, 20 zone and Central zone), which were successful in hitting more high-grade gold, significant low-grade halos of mineralization as well as delineating further mineralization at depth. High-grade highlights include:
• DO-17-202: 9.0 metres at 4.53 grams per tonne gold (including 1.5 m at 15.7 g/t Au);
• DO-17-200: 4.5 m at 4.68 g/t Au;
• DO-17-197: 1.2 m at 13.35 g/t Au;
• DO-17-187: 1.1 m at 4.84 g/t Au and 1.5 m at 4.13 g/t Au.
DO-17-202 and DO-17-200 demonstrate the potential for higher grades and additional ounces with further drilling along the northern boundary of the Porphyry zone (the North zone), while DO-17-187 expanded known mineraliza-
tion at the southern edge of the main Porphyry zone. In addition to the high-grade results, significant lower-grade mineralization was also intersected in a number of the recently received assay results. Highlights include:
• DO-17-197: 23.9 m at 0.51 g/t Au;
• DO-17-194: 14.0 m at 1.37 g/t Au and 6.0 m at 1.28 g/t Au;
• DO-17-192: 33.0 m at 0.55 g/t Au and 10.2 m at 0.77 g/t Au;
• DO-17-187: 10.5 m at 1.45 g/t Au, six m at 1.12 g/t Au, 7.5 m at 0.86 g/t Au and 9.0 m at 0.56 g/t Au;
• DO-17-182: 7.5 m at 1.03 g/t Au, 15 m at 0.47 g/t Au and 13.5 m at 0.46 g/t Au. DO-17-192 expands known mineralization between the Porphyry zone and 20 zone, and DO-17-182 extended known mineralization down to more than 600 metres in depth.
Aurvista’s president and chief executive officer, Matthew Hornor, stated: “We are very encouraged with the latest assay results within this core central segment of the porphyry system at Douay. We see great potential to add ounces by linking zones of mineralization, our technical group will update internal models and focus on the highest-priority targets in subsequent drill campaigns.”
Assay results were received from a final drill hole at the Douay West zone (DO-17-190), located on the eastern edge of the zone, returned 7.5 m at 1.39 g/t Au and indicates the potential to more than double the original Douay West zone footprint with further drilling. This result builds on previously announced drill results (see news releases dated Feb. 22, April 3 and May 8, 2017). Additional Douay West zone expansion targets will be followed up in subsequent drilling campaigns.
Another objective of the spring-summer 2017 drilling campaign was to test the NW Porphyry extension target area. A total of 20 stepout and widely spaced (200 to 400 metres) drill holes were completed and confirmed the porphyry system extends to the northwest. Included in the assays reported today are an additional 11 drill holes (4,102 metres), with several drill holes intersecting gold mineralization. Highlights include:
• DO-17-181: 2.1 m at 3.25 g/t Au and 1.0 m at 1.93 g/t Au;
• DO-17-189: 4.6 m at 0.88 g/t Au, 5.1 m at 0.64 g/t Au and 7.1 m at 0.46 g/t Au;
• DO-17-191: 7.0 m at 0.61 g/t Au;
• DO-17-193: 4.5 m at 0.50 g/t Au, 4.5 m at 0.45 g/t Au and nine m at 0.45 g/t Au.
There are very few historical drill holes within the five-kilometre-long-by500-metre-wide NW Porphyry target area and the current drilling campaign was successful in establishing the potential for a new lower-grade gold segment and extension of the porphyry mineralization. The company also completed 11 exploration drill holes targeting gold-bearing volcanogenic massive sulphide style mineralization at the EM conductor target areas (E and G). Minor highlights included DO-17-176: 1.5 m at 1.81 g/t Au at the conductor E target; and DO-17-201A: 6.4 m at 2.77 per cent zinc at the conductor G target.
The 2017 spring/summer drilling campaign successfully expanded a number of mineralized zones and drilling continued to intersect gold mineralization. The main structural corridor has a known strike length of 10 km with significant exploration upside. Aurvista plans to have a technical committee of experts visit the Douay gold project in early August as the company refines its go-forward exploration and drilling plans.
We seek Safe Harbor.
