The Goldrush Project

Goldrush Mining projects have an easy-manageable risk taking into consideration the following aspects:

Alluvial vs. In-Situ mining:

– Cleaner, quicker to deploy, safer for employees and mobile

Permits:

– Efficiently managing potential competition
– Very friendly environment to promoter

Region:

– Area looking favorable to local employment

Technology Selected:

– Much more efficient extraction method and earth moving system
– Best mobile gold ore processing stations

Security Procedure:

– On-site manpower and remote command control for audio-video
– Gold concentrate airlifted by helicopter and treated remotely in secure location

Environmental:

– Safer as no chemical used
– Earth moving equipments compliant with EU environment standards
– Possibility of creating improvement to river banks to prevent flooding at strategic area of river

Description of mining operations

The alluvial ore material will be extracted from the riverbed and terraces using high performance dredging equipment, with powerful submersible pump equipments and excavators. Following this process, the material is transmitted to the placer washing plant using the discharge pipeline system, which connects the dredging unit to the processing unit. The dredging unit is delivered by prestigious providers of hydraulic excavators, dozers and submersible pumps and contains the suction unit module and the discharge module. The processing unit aggregates equipments for washing and mechanical screening in multiple phases until the final concentrate is obtained.

From a modular point of view, the processing unit contains the following blocks: alluvial ore dredging equipment with discharge pipeline system, shaking deck, sluice boxes, screens, concentrators. The sites also contain annexed units that allow an optimal performance for the dredging & processing units: diesel generators, jet water pumps, slurry pumps, hydraulic systems, drilling equipment based on sonic technology, belt conveyors, electric control cabinets, earthmoving equipments, administrative buildings.

Workflow

  • the alluvial ore material is extracted from the riverbed area using the submersible suction pumps, installed on the excavator located on the riverbed or on the riverbanks
  • the alluvial ore material is extracted from the riverbanks area using the hydraulic excavators
  • the ore material extracted from the riverbed is transported to the processing washing plant unit through the discharge pipeline system, the ore being prewashed into the pipeline while passing through it
  • the ore material arrives prewashed in the inclined shaking deck of the processing unit, where a first sorting and washing process is performed – the accepted size or sand & gravel are moved further into the next level compartment unit and the oversize tailings are rejected and assigned to be moved using the earth moving machines back to the river. Earth moving machines consist in: excavators, wheel loader and belt conveyors
  • the sluice box, as integrated part of the inclined shaking deck will capture the small nuggets of gold that passed through the first stage of the sorting process, together with the heavy minerals
  • the accepted material, sustained by the slurry pump unit, gets into the Vibrating Screen, where the second level of the separating process is performed through high-quality polyurethane media screens. Then, the accepted material will pass into the Knelson centrifugal concentrator unit, where another separating process is performed using g-force and centrifugal force. The concentrate resulted in this phase will be directed to the final level of processing (the finest size)
  • the finest level of processing takes place in a separate secured location on the vibrating/shaking Gemini type gold table, where the micron size of gold are separated

High Standards

The processes of the Goldrush Mining project are fully mechanical and ecological – the washing water is recirculated via hydraulic systems and the tailings are reintegrated into the natural environment, because chemicals are not used at all into the process.

Our Company standards is to assure the security and surveillance of the sites and the gold route with certified security companies with high experience in the domain and with an appropriate insurance. As an improvement feature, the Company also uses helicopter transportation services, for a safe and quick transfer between the plant’s locations to the external destinations (final cleaning).
