Target Deposit Type
The VBW Project represents an analogous precious metals exploration target akin to the Company's Eagle Gold Deposit, large-tonnage, intrusion-related gold systems associated with Cretaceous Tombstone and Mayo suite granodiorite intrusions and structurally-controlled high-grade gold-sulphide ± silver-sulphosalt veins.
In November 2011 Victoria Gold staked 1,012 quartz mining claims, covering approximately 205 km2 (20,500 hectares) of First Nation of Na-Cho Nyak Dun (FNNND) Category B lands immediately to the west of its Dublin Gulch Property. Surface rights on the Category B Lands belong to the FNNND and are part of the FNNND's final Umbrella Agreement with the federal and territorial governments. The FNNND signed an agreement giving consent to Victoria for staking claims and conducting exploration on the Category B Lands.
The VBW Claim Block covers the southwest strike extent of the highly prospective Potato Hills Trend, which is defined by several outcropping granodiorite bodies and a number of large-scale faults that potentially host mineralization similar to the Company's flagship Eagle deposit. The Claim Block, (Figure 1, highlighted in green), is considered highly prospective for intrusion-related gold system (IRGS) type mineralization and had not seen any mineral exploration activities in over 20 years. Historical exploration on the VBW Property included mapping and sampling by the Yukon Geological Survey in the mid-1990's, and minor, poorly documented prospecting for gold and silver in the early- to mid-20th century.
Geology and Mineralization
The VBW claims are underlain by Hyland Group metasedimentary rocks with minor outcropping igneous rocks. The VBW claims cover the southwest extension of the Potato Hills Trend, a > 13 km long zone of gold mineralization and geochemical anomalies corresponding with the regional-scale Tombstone High Strain Zone and the northwest contact of the Dublin Gulch granodiorite. Felsic igneous rocks interpreted to be of similar chemistry and origin to the Dublin Gulch granodiorite outcrop in the central part of the claims. In the southern part of the VBW claims YGS geologists mapped a 2 km east-west trending zone of contact metamorphism in the Hyland Group metsedimentary package but did not identify a contributing intrusion in the vicinity, although the presence of a hornfels zone strongly suggests a proximal buried plutonic body.
2012 VBW Program Summary
2012 VBW Program Highlights
- 2012 program delineated 5 km long east-west trending soil anomaly > 20 ppb Au coincident with oxidized breccia and fault in VBW claim block.
- 2012 Mapping identified outcropping granodiorite stock, breccia, tourmaline alteration and hornfels sediments.
*See the Eagle Gold Project page for details of the Eagle NI 43-101 Resource estimate.
Exploration in the VBW claim block commenced in August of 2013 and comprised of a 1,454 soil sample grid at a 50m by 100m spacing and 36 regional stream sediment samples; and a helicopter-supported mapping and rock chip sampling program conducted by Victoria Gold Corp. The mapping program focused on anomalous arsenic values from the soil sample grid as provided by real-time XRF analysis in the field, and on continuation of the 2012 mapping to the west of the main ridge area. In total, 43 rock-chip samples were collected throughout this program.
2013 VBW Program Summary
Results from a first phase 2103 mineral exploration program confirmed an extensive gold >40ppb and coincident copper-arsenic anomaly with highs up to 1.02 g/t Au. The zone consists of an area of stockwork quartz-veined Hyland group metasediments, local faulting, and mid-Cretaceous age granitoids of the Tombstone Plutonic Suite. Characteristics of contact metamorphism in the sediments is evident extending 2km east-west in the vicinity of the highest soil values in VBW. The intrusions are interpreted to be of similar character to the Dublin Gulch stock, which hosts the company's 6.3 M oz Eagle gold deposit, located 15 km to the east.
Based on the tenor and size of the Gold/Arsenic-in-soils geochemical anomalies uncovered and the success of the geological mapping and sampling programs in September 2013, a decision was made to drill test the VBW target in Fall, 2013.
Victoria's inaugural drill program on the VBW Claim Block was conducted during October 2013 and was designed to test the arsenic and gold in soil anomaly proximal to the mapped intrusive exposures and interpreted structural intersections. The program consisted of 958 m of HQ core. Results from this program are tabulated below:
Table 1- 2013 Falcon diamond drilling results.
|Drill Hole||From (m)||To (m)||Length (m)||Grade (g/t Au)|
The program was successful in defining widespread, pervasive gold mineralization of >0.5 g/t Au and resulted in VIT's latest gold mineralization discovery within the Potato Hills Trend -- the Falcon Zone.
The four drill holes intersected hornfelsed and heavily tourmaline altered Hyland Group metasediments with varying degrees of oxidation and vein intensity. Three major fault and shear structures intersect in this area with south, west, and north-west strike and moderate to near vertical dips. Higher grade intercepts in the drill core up to 6.32 g/t Au correspond to faulted areas, however lower grade gold mineralization is consistently present though much of the hornfelsed country rock. Minerals found within the veins and disseminated in the sediments include arsenopyrite, realgar, chalcopyrite, pyrite, bismuthinite and rarer galena.
One intensely tourmaline-brecciated granodiorite dyke was intersected in hole VBW13-03C, but the main intrusive body that outcrops at surface was not intersected.

Future exploration at the Falcon Zone and VBW Project will include:
- Property-wide airborne magnetic and radiometric surveys to identify possible buried intrusions and provide structural and stratigraphic information otherwise unobtainable due to the lack of outcrop and significant vegetative cover below the tree-line
- Expanded soil geochemical surveys from the Falcon discovery and on additional exploration targets to the North
- Expanded mapping and prospecting programs on Falcon Zone and Property wide
- Continued diamond drilling of the Falcon Zone along the projected strike of the defined mineralized structural zone
