Climate Impact & Sustainability Data (2005-2009, 2021)

Dust and transport vehicle night time noise emissions exceeding statutory limits at Shangwanxin Village.
Potential for plumb vibration levels from mine blasting causing shaking of buildings near Luzhou and Jianggen Villages and the proposed Textile College site.
Potential risk to groundwater resources from leached metals or acid drainage from the TSF and WSF due to variable soil and rock permeability.
Potential for groundwater drawdown resulting in surface subsidence, cave-ins, or fracturing, affecting groundwater wells and fish ponds in nearby villages.
Geological hazards such as landslides and surface cave-ins near the Fuwan Water Plant, Gaoming-Gaoyao road, and the mouth of the valley of the proposed Waste Rock Facility (WRF).

Wetting down access roads during dry and windy conditions and prohibiting night time transportation.
Developing a blasting plan that limits explosive weight, number of holes per shot, and time delay between shots.
Conducting a geotechnical survey to determine TSF and WSF basement permeability and installing natural liners if necessary; installing groundwater monitoring wells.
Conducting additional investigations into groundwater drawdown, including a water balance study; quantifying potential effects of drawdown.
Undertaking additional work to understand the geotechnical state of ground above the proposed underground mine; identifying areas prone to subsidence or cave-in and determining at-risk properties.

Frameworks Used: NI 43-101

Significant delays in the renewal of exploration permits of both the Fuwan Silver Deposit and Changkeng Gold Project.
Travel restrictions in connection with Covid-19 since early 2020, resulting in limited site visits.
The Covid-19 outbreak has spread throughout the world since early 2020, causing companies and various international jurisdictions to impose restrictions, such as quarantines, closures, cancellations and travel restrictions.

Renewal of exploration permits for Fuwan Silver Project (5 years) and Changkeng Gold Project (2 years).
Continued permitting process to obtain mining licenses on both projects.
Strategy to secure a large Chinese mining group as a business partner to develop the Fuwan Project and the adjoining Changkeng Project.
