Toronto, Ontario – Aurvista Gold Corporation (“Aurvista” or the “Company”) (TSX-V: AVA, OTC: ARVSF) announces the results from two ground Induced Polarization (“IP”) surveys completed in Q1-2015, as well as thirteen regional IP surveys which have now been interpreted as a continuation of the Company’s ongoing Generative Program (the “Program”) at the Douay Gold Project (“Douay”).
Geosig Inc. (“IOS”) of Quebec City (Quebec) was contracted for the two IP surveys under the supervision of Mr. Yvan Bussières. P. Eng., Aurvista’s lead consultant for the Program, who completed the interpretation. The ground surveys were combined with the eleven IP surveys done over the years at Douay and were interpreted into a single database (refer to the appended Figure 1). IP and the other geological-geophysical components of the Program will be essential in identifying any new mineralization and new exploration targets at Douay.
The recently completed 68.6 new line-kilometer IP survey covered gaps in geophysical data in the extreme NW corner of Douay and the western end of the previously defined Porphyry Zone. The Porphyry Zone sector hosts the majority of the lower grade gold mineralization at Douay and overlaps with the newly defined base metal target area west of the South Porphyry. Results from both sectors show a match between IP and the previously interpreted airborne Magnetic and EM-INPUTTM surveys (Figure 1; refer to the Company news releases dated April 8, 2015, and December 16, 2014).
- Areas of lower IP resistivity correspond to wide swaths of deeper overburden in the central and eastern portions of Douay;
- Where narrower linear IP resistivity lows occur they are overlapped by similar linear EM-INPUTTM anomalies, corresponding to conductive linear and recessive fault-bearing graphite typical of the Casa Berardi Deformation Zone (the “CBDZ”), as well as graphite- and sulphide-rich mudstones and cherts;
- These narrow linear IP resistivity lows mirror the complex array of faults of the CBDZ crisscrossing Douay with consistent E-W, NE-SW and NW-SE trends forming anastomosing patterns - as in the case of the Douay West Zone, the gold mineralization appears to sit at the junction of two anastomosing faults;
- Smaller groupings of EM INPUTTM anomalies located in felsic and mafic volcanic rocks are associated with more discrete areas of higher IP resistivity, likely a non-graphitic component to the conductors, such as sulphide-bearing cherts and massive sulphides;
- The largest of these EM INPUTTM groupings spans some 4 kilometres in length, containing a 1 km wide series of conductors with higher IP resistivity running westwards from the South Porphyry; and
- A similar 3.7 km long segment of EM-INPUTTM conductors and IP-resistivity highs occurs along the northwestern most occurrence of the Casa Berardi Deformation Zone, where previous drilling also indicated sulphide-bearing cherts and massive sulphides, this time anomalous in Copper, Zinc and Silver - historical drill hole #J8 intersected 0.16% Copper and 16.5 g/t Silver over 0.9 meters; whereas historical drill hole #54493 gave 0.18% Zinc over 8.9 meters.
As part of further expanding the generative work, the Company will initiate a lithogeochemical study which will assist in defining primary lithologies and secondary alteration gradients induced by hydrothermal-related processes for gold and/or base metal mineralization. Lithogeochemistry will be crucial in vectoring towards potential new mineralization along the 20 km length of the CBDZ on Douay. Aurvista will uniformly cover Douay by re-sampling drill core from 26 North-South project-wide sections at 500 meters to 750 meters intervals, analyzing this core for major and trace elements with complementary petrography, and finally alteration-mineralization vectoring. The work is ongoing and expected to be completed in Q4-2015.
