➢ The company has commissioned SRK Consulting to complete a structural review of the ATO - Mungu epithermal system. This is

nearing completion and is expected to deliver significant gains to future drilling efforts.

➢ The Stage 3 drilling program targeted at the ATO4-Mungu trend will commence towards the end of September.

➢ Soil sampling, rock chip sampling and geophysics has highlighted four new discoveries at the Uudam Khundii Project in

Bayankhongor gold province

➢ The largest of the new discoveries is the Altan Sum Discovery which is a gold anomaly measuring approximately 3km x 0.5 km

with soil samples up to 289 ppb gold and rock chips up to 1.38g/t gold.

ALTAI TSAGAAN OVOO GOLD PROJECT (ATO)

DEVELOPMENT

The Company is now targeting completion of site construction by the end of 2018 and will be pushing hard

to deliver first gold as soon as possible. The Project has experience d some recent delays due to

circumstances outside of the Companies control. These issues have now largely been resolved and

construction is now full speed ahead.

All materials for the crusher and leach pad have been delivered to site and construction is now underway.

Mining camp accommodation and restaurant has also been completed and commissioned.

Initial mining and prestrip was completed on the ATO1 deposit with ores being stockpiled for crushing.

Mining will now recommence on completion of the ADR plant and final licensing.

The ADR plant fabrication has been completed and has been inspected by company representatives. The

plant will now be mobilized to site for immediate construction and commissioning.

The Company will be pushing hard to achieve all objectives by late 2018, but warns that weather events and

the onset of winter could possibly hamper the production of initial gold.

DRA Global has been appointed to manage and undertake a bankable feasibility study on the expansion of

the ATO Gold Project to a 150,000oz gold per annum CIL gold silver operation. The study will be based on

existing fresh rock ores at ATO1,2,4, in addition to the potential being seen at ATO4 - Mungu.

ATO DRILLING

The Company has now completed a total of 126 drill holes for 17,892 meters since acquiring the project in

late 2017. Exploration results have been excellent and the exploration team led by Enkhtuvshin Khisigsuren is

congratulated.

The Stage 2 drilling program was recently completed with three diamond core drilling rigs completing a

total of 9,006 meters. Results have now been received and are reported in this release. The program was

highly successful and focused on the ATO4 end of the ATO4-Mungu mineralized trend. The Stage 3 drilling

program will commence towards the end of the month and will again focus on the ATO4 – Mungu trend.

Some additional oxide infill drilling will also be completed at the ATO2 to improve the current resource and

mine model on that deposit.

The completion of the Stage 2 drilling program saw the identification of the first ever visible gold seen at ATO

project, with super high gold grades being returned in ATO299 and ATO317. This is highly encouraging as the

company further develops its understanding of the ATO Mungu epithermal system as more high grade zones

are being identified.

The company has commissioned SRK consulting to complete a structural review of the ATO - Mungu

epithermal system with a particular view on developing a better understanding of high grade mineralization.

This is nearing completion and is expected to deliver significant gains to future drilling efforts.

UUDAM KHUNDII GOLD PROJECT

The Company has had a very busy summer at the exciting Uudam Khundii Gold Project in the Bayankhongor

gold province with some outstanding early results being returned. Soil sampling, rock chip sampling and

geophysics has highlighted four new discoveries all of which will be further tested in the coming months

with trenching and mapping prior to the commencement of initial drilling.

The largest of the new discoveries is the Altan Sum discovery which is a gold anomaly measuring

approximately 3km x 0.5km with soil samples up to 289ppb gold and rock chips up to 1.38g/t gold.

Additional discoveries have been made at Golden Steppe discovery with a peak soil anomaly of 34ppb gold

and rock chips up to 5.39g/t gold, the Blue Hills discovery with a peak soil anomaly of 38ppb gold and rock

chips up to 1.37g/t gold and the Milky Way discovery with a peak soil anomaly of 82ppb gold and rock chips

up to 2.04g/t gold

In total the Company has now completed 2,400km of ground magnetic surveys, 90.8km of IP Dipole-Dipole

surveys, 8,427 soil samples and 346 rock chip samples.
