In 2016 drilling extended gold mineralisation 1.3 kilometres along strike.

Drilling also discovered two new mineralised zones parallel to the JORC gold resource with intervals of 6 metres at miglior software demo per opzioni binarie 38 g/t anali tecnica gold (Lower Gold Zone) and 9 metres at binary options trading strategy youtube 6.8 g/t gold (Camp Gold Zone).

Metallurgical test work on all mineralised intervals drilled to date (182 intervals) has revealed an overall total gold recovery of 99% based on intensive cyanide leaching. Gravity recoverable gold (gold recovered from the gravity concentrate) is also exceptionally high at 88.6%.

The license has just been extended to December 2020 and a major drilling campaign in 2017 is targeted to increase the inferred and indicated resource to investing group bnary option 500,000 to 600,000 ounces dove vanno a finire i soldi degli opzioni binarie [1] of gold at high grades binäre optionen club from surface and within open pit designs. The Company aims to convert the exploration permit into a mining permit in 2018.

iq optionj 2017 Exploration Target

The Company has an exploration target in 2017 of defining www avatrade it 500,000-600,000 ounces consisting of 2-3 million tonnes of ore at 4-6 g/t gold. The target is derived from the existing average grade of the current resource which has an average grade of 5.2 g/t gold.

The drilling program will test several targets starting at the high grade quartz zone that currently contains 244,000 tonnes at 9.5 g/t gold containing 75,000 ounces of gold where around 1200 metres of reverse circulation will be conducted. Following this, further drilling will be conducted at the lower Gold Zone, Camp Gold Zone, Upper Gold zone and the Sandstone Zone.

The drilling will focus on defining indicated and inferred resource. That can be economically mined via open pit.

Introduction

Discovered in 2014 based on previous copper exploration in the region that highlighted high gold rock chip values initial trenching identified 7 metres at 30 g/t gold and follow up reverse circulation drilling in 2015 and 2016 quickly defined a gold resource of 1.8 Million tonnes at 5.2 g/t containing 302,000 ounces of gold.

Drilling in 2016 identified the high grade Quartz Zone that contains 244,000 tonnes at 9.5 g/t for 75,000 ounces. The Quartz Zone is open along strike has been mapped for at least two hundred metres which will be tested in the first drill program.  Mineralisation starts at surface is open along strike at either end and at depth below the drilling.

Location and Infrastructure

The Aucu Gold project is located in the central Asian Kyrgyz Republic 350 kilometres west of the capital Bishkek.

The project is accessible by bitumen sealed roads from either Jalalabad to the South or Bishkek to the North.

The local valley has a population of approximately 25,000 people at the southwestern end with isolated small villages to the northeast. The Aucu project is located 25 kilometres for the nearest village in a side valley that is uninhabited and ranges in elevation from 2000 to 3600 metres in elevation.

The region is serviced with 2G telephony and grid power with major mining services available at Taraz to the North and Namagan to the South.

There are several mines in the immediate vicinity including the two recently commissioned gold mine Ishtamberdy (5 Moz) and the Gold and copper mine Bozymchak (1.2 Moz).

Licence Tenure

The Exploration license has been held since 2006 and has been renewed twice. During December 2015 the Kyrgyz State Agency for Geology and Mineral Resources (SAGMR) issued a five year extension to the Company’s exploration license (AP 590) with an expiry date of 31 December 2020. The license can be converted into a mining licence once a minerals resource has been defined.

Geology and Gold Mineralisation

The Aucu gold deposit is hosted in sandstones, conglomerates and minor granodiorites that flank a series of felsic porphyry intrusions considered to be responsible for both epithermal gold mineralisation and copper porphyry mineralisation. The intrusion of the porphyry into the sedimentary sequence has resulted in tectonic uplift and extensive faulting. As gold bearing fluids flowed away from the central porphyry along faults and shear zones in the sandstones the gold bearing fluids cooled and the gold deposited as native gold associated with quartz veining in the faults and shear zones. Native gold have been extracted for surface outcrops of the quartz veins over an elevation change of 500 metres suggesting that the gold bearing structures will have substantial depth extent.

Drilling, trenching and mapping in 2014 -2016 identified six major parallel mineralised systems that extend more than 3 kilometres and are unexplored beyond this.

The mineralised zones are parallel to the existing zones and consist of:

The Upper and Lower Gold Zones (UGZ, LGZ)) that consist of two sub-parallel mineralised shears zones and quartz veins approximately 300 metres long zone have a resource of 164,000 ounces. Mineralisation starts at surface is open along strike at either end and at depth below the drilling.

The Quartz Zone (QZ) that occurs 1.2 kilometres along strike from the Upper Gold Zone and consists of a 500 metre long zone that has been tested over 300 metres and has a resource of 75,000 ounces. Mineralisation starts at surface is open along strike at either end and at depth below the drilling.

The Sandstone Zone (SZ) that occurs 900 metres East of the UGZ and consists of a 400 metre long zone with drilling results including: 4 metres at 60 g/t gold, 2 metres at 43 g/t gold and multiple other intersections at similar grades. Mineralisation starts at surface is open along strike at either end and at depth below the drilling.

The Eastern Gold Zone (EGZ) that occurs 1.5 kilometres east of the lower gold zone within granodiorite with drilling results including: 3 metres at 6.97 g/t gold, 3 metres at 4.33 g/t gold and an additional 3 metres at 3.56 g/t gold.

The Camp Gold Zone (CGZ) that occurs 400 metres south of the LGZ within sediments with drilling results of 9 metres at 6.83g/t gold The CGZ was initially identified from trenching results of 3 metres at 23.8 g/t gold.

Metallurgical Test Work

Preliminary metallurgical test work revealed an average total overall gold recovery of 98.9% from intensive cyanide leaching of both the gravity concentrate and gravity tailings. The total gravity recoverable gold averaged an exceptional 88.6% from intensive cyanide leaching of the gravity concentrate.

The test work was conducted on 182 one metre RC samples which were composited into 69 samples representing each ore intersection from every hole. The samples represent ALL the mineralised intervals sampled from the 2014 and 2015 drill programs.

Further investigation of the test work revealed an average overall gold recovery of 99% for the samples that represent the current JORC Compliant resource (1.8 Million tonnes at 5.2 g/t gold). The above results indicate that all of the JORC Compliant Inferred resource is likely to have very high average recoveries and further, will be amenable to standard processing methods.

2017 Exploration Program

The Company has an exploration target in 2017 of defining 500,000-600,000 ounces consisting of 2-3 million tonnes of ore at 4-6 g/t gold. The target is derived from the existing average grade of the current resource which has an average grade of 5.2 g/t gold.

The drilling program will test several targets starting at the high grade quartz zone that currently contains 244,000 tonnes at 9.5 g/t gold containing 75,000 ounces of gold where around 1,200 metres of reverse circulation will be conducted. Following this, further drilling will be conducted at the lower Gold Zone, Camp Gold Zone, Upper Gold zone and the Sandstone Zone.

The drilling will focus on defining indicated and inferred resource. That can be economically mined via open pit.

Potential Development Options:

The Company is currently considering development options including an initial 75,000 Oz production rate once the pit optimised open pit resource reaches 500,000 ounces.

Preliminary economic calculations indicate that most of the existing resource can be mined at very high margins via a simple crushing grinding and gravity extraction circuit.

In 2017 the company is collecting metallurgical and geotechnical samples to allow a preliminary evaluation to be conducted on pit wall angles, and gold recovery
