Aurvista Gold Highlights Historic Gold Assay Intervals as Part of Detailed Targeting Work
MONTREAL, QUEBEC--(Marketwired - Aug 9, 2016) - Aurvista Gold Corporation ("Aurvista" or the "Company") (TSX VENTURE:AVA)(OTC PINK:ARVSF)(FRANKFURT:AV2) is pleased to highlight historic and more recent diamond drill hole results from the 40 plus years of exploration work at its Douay Gold Project ("Douay") in 15 major exploration programs. Douay is located 40 km SW of the Matagami Zinc Base Metal Camp and 150 km N of the Val-d'Or-Malartic Gold Camp (both in Quebec).
As a number of new exploration projects in Quebec have been making headlines in recent months, Douay still remains one of the premier undeveloped gold projects in Quebec based on its past drilling results and Mineral Resources estimates*. Selective historic gold assay intervals from the higher gold grade zones at a cut-off grade at 5 g/t gold are outlined in the following table (refer below for a complete list of assay intervals, and refer to Tables 3 and 4):
| GOLD | CORE | ||||
| DDH # | GRADE | FROM | TO | LENGTH* | GOLD |
| (year drilled) | (g/t) | (m) | (m) | (meters) | ZONE |

Douay was initially explored from 1973 to 2010 for its higher grade gold potential with the discovery of 7 lenses ("Douay West", "10", "20", "531", "Central", "Main" and "NW"), followed by the 2005 discovery of a lower grade bulk gold porphyry (the "Main Porphyry").
Exploration of the "Main Porphyry" was revived by Aurvista during the Company's 2011 and 2012 drilling campaigns in light of the exploration and mining successes at the multi-million ounce Canadian-Malartic and Detour Lake bulk lower grade gold deposits. Drilling of the "Main Porphyry" led to the discovery of an additional higher grade lens, the "Adam-Porphyry" Zone, and a lower grade corridor ("South Porphyry").
It is important to remind shareholders, stakeholders and prospective investors of past exploration successes at Douay leading to the discovery of the 8 higher grade zones and the 2 lower grade corridors within a 10 km by 3 km wide segment (or 30 km2) of the 20 km trend of the Casa Berardi Deformation Zone (the "CBDZ") on Douay (refer to the Company news releases dated December 17, 2014). All of this work recently led Aurvista to define a sizeable Mineral Resource estimate*: representing 2.7 million tonnes at 2.76 g/t gold for 0.2 million ounces of gold in the Indicated category with an additional 115 million tonnes at 0.75 g/t gold for 2.8 million ounces of gold in the Inferred category (at a 0.3 g/t gold cut-off), or 2.5 million tonnes at 2.98 g/t gold for 0.2 million ounces of gold in the Indicated category with an additional 61.8 million tonnes at 1.06 g/t gold for 2.1 million ounces of gold in the Inferred category (at a 0.5 g/t gold cut-off grade).
Aurvista remains committed to the continued exploration of Douay with its near term exploration objective of increasing the quantity and quality of mineral resources by extending the higher grade gold lenses or by defining new ones with gold grades similar to those intersected in the past (refer to the table above, and Tables 3 and 4.)
Aurvista's management firmly believes:
| • | The upside potential of the under-explored Douay Project is significant for a lower grade bulk gold-type system containing a number of higher grade gold lenses of variable sizes and grades; | |
| • | There has never been any historical mining on Douay, hence the higher grade gold lenses remain intact; | |
| • | Less than one-sixth of the Camp-scale size gold system at Douay has been explored via diamond drilling in any detail based on the distribution of the known higher and lower grade gold zones and location of drill holes; | |
| • | The gold system remains open along strike beyond the 10 km known trend and at depths below -400 m; | |
| • | The main gold target is the largely untested "Main Porphyry", encompassing the Adam-Porphyry Zone. which was Aurvista's 2012 discovery containing (at a 3 g/t gold cut-off) 383,000 tonnes grading 22.29 g/t gold for 274,500 ounces in the Inferred category within a lower grade envelope of 55.1 million tonnes at 1 g/t (at a 0.5 g/t cut-off) also in the Inferred category, and the "South Porphyry"; | |
| • | The "Main Porphyry" is flanked by the largely unexplored NW Zone which to date contains 1 million tonnes grading 2.71 g/t for 87,000 ounces of gold in the Inferred category, and the Douay West Zone containing 2.33 million tonnes at 3 g/t gold for 225,000 ounces in the Indicated category and an additional 1.26 million tonnes at 1.8 g/t gold for 73,000 ounces in the Inferred category (both zones at a 0.5 g/t cut-off); and | |
| • | Douay West is sufficiently advanced in order to go into pre-feasibility or feasibility mode if deemed beneficial. |
Douay has seen 15 major exploration programs since 1973 (Table 1 can be accessed using the following link):
| • | The first 13 programs were focused on the discovery and exploration of 7 higher grade gold zones over an 8 km stretch of the Casa Berardi Deformation Zone; | |
| • | From 1973 to 2010, the previous vendors completed 144,783 meters of drilling in 575 diamond drill holes, while Aurvista completed the last two programs and essentially focused its efforts on the higher grade Douay West Zone and the lower grade bulk gold porphyry, and drilled from 2011 to 2014 some 42,955 meters in 127 diamond drill holes; and | |
| • | Aurvista's drilling led to the discovery of 1 higher grade gold lenses - the "Adam-Porphyry" Zone - and 2 lower grade bulk gold target - "Main Porphyry" and "South Porphyry"; |
Diamond drilling for the entire project was mostly focused on the higher grade gold zones:
| • | Diamond drilling totaled 187,738 meters in 702 drill holes (Table 2 can be accessed using the following link), with an additional 165 Reverse Circulation drill holes dating from the late 1980's; | |
| • | There were 95,941 individual samples taken for gold assays, of which 317 assay intervals greater than 0.3 g/t gold were composited to delineate the 7 higher grade gold zones (Table 3 can be accessed using the following link) demonstrating the kilometric distribution, variability and continuity of the gold mineralization from bedrock surface to a -400 meter depth over a known 8 km strike length; and | |
| • | There are 43 assay intervals greater than 5 g/t gold from the "Douay West", "Main", "531", "10", "20", "Adam-Porphyry" and "NW" zones (Table 4 can be accessed using the following link) |
Aurvista is committed to the continued exploration of Douay
The Company is planning a two-staged exploration campaign on the Project for the period June to December 2016 with the prime objective of determining the best of the 25 defined targets identified in 2014-2015 with a view of significantly increasing the current Mineral Resource estimates*.
The First Stage campaign will complete the Priority Targeting Program (the "Program") in two areas where management is confident additional gold mineralization will be discovered, the first being in the 8 km by 3 km wide (at its longest and widest points) SE-tilted parallelogram-shaped polygon enclosing the Douay-Style Mineralization ("DSM") containing all the known gold zones ("Douay West", "10", "20", "531", "Central", "Main", "NW", "Adam-Porphyry", "Main Porphyry" and "South Porphyry") and current Mineral Resource estimates*. The second area is the 6 km by 1 km wide cluster of EM INPUT™ anomalies conductors running along the southwest boundary of the DSM that have affinities to Volcanogenic Massive Sulphide or VMS mineralization associated with gold. The Second Stage campaign will consist of a 4,000 meters of drilling to delineate additional gold and/or copper-gold mineralization on the best targets.
The Summer Program will include:
| • | Completing an airborne geophysical Magnetic, Electromagnetic and Radiometric survey of the central portion of the Douay Project to define key contacts and faults which could be linked to gold and any potential base metal bearing massive sulphide lenses within the 6 km by 1 km Copper-Gold corridor to a depth of -150 meters. | |
| • | Re-logging selective previous and historical drill core for litho-geochemical and thin section work along key gold mineralized and non-mineralized sections across the Douay Project, all to define the chemical signatures and alteration mineralogy of the known gold and/or base metal mineralization. This will assist the airborne geophysical survey in the vectoring towards additional gold mineralization; and the drilling of the best priority targets that could potentially lead to the expansion of, and better quality, mineral resources. |
