Excavation is the fundamental physical process that makes gold mining possible. At Eldoreydo Mining, we plan and execute all earthworks — from initial topsoil stripping and bulk waste removal through to precise ore excavation and pit development — with the discipline, equipment capability, and technical expertise needed to move large volumes of material safely, efficiently, and in full compliance with the approved mine plan.
Eldoreydo Mining operates a modern fleet of excavators, loaders, dozers, and support equipment, maintained to high availability standards through structured preventive maintenance programmes. Our equipment operators are trained, licensed, and experienced in open-pit and bulk earthworks environments. All excavation activities are planned and supervised by qualified mine engineers and site supervisors with direct accountability for safety, productivity, and cost performance on every shift.
How does Eldoreydo Mining plan its excavation programmes?
Every excavation programme at Eldoreydo Mining begins with a detailed mine plan developed by our engineering team using industry-standard mine design software. The plan defines the sequence of waste stripping, ore extraction, and pit development in a way that optimises the strip ratio, maintains access to ore, and manages geotechnical risk throughout the life of the pit. Short-term plans — typically weekly and monthly — are developed from the long-term design and used to direct day-to-day excavation activities on site. All plans are reviewed and updated regularly as new geological data becomes available from ongoing grade control sampling.
What drill and blast methods does Eldoreydo Mining use?
Drill and blast is the primary method Eldoreydo Mining uses to break rock in open-pit operations. Our blast engineers design each blast to achieve the target fragmentation size for the downstream crushing and grinding circuit, balancing explosive energy, burden and spacing geometry, and timing to produce a consistent, well-broken muck pile that is easy to load and haul. We use electronic detonators on all production blasts, which provides precise timing control and minimises vibration and flyrock. Pre-blast exclusion zones, community notification protocols, and post-blast inspections are standard practice on every site.
How does Eldoreydo Mining manage pit wall stability during excavation?
Geotechnical management is an ongoing and critical part of all Eldoreydo Mining excavation operations. Our geotechnical team conducts regular mapping of pit walls and installs monitoring instruments — including prisms, extensometers, and in some cases radar monitoring systems — to detect movement early. Pit slope designs are developed by qualified geotechnical engineers based on rock mass characterisation data, and slope angles are reviewed and updated throughout the life of the pit as conditions evolve. All personnel working near pit walls are trained to identify warning signs of instability, and we maintain strict exclusion protocols whenever movement is detected.
How does Eldoreydo Mining minimise the environmental impact of excavation?
Excavation inevitably disturbs the land surface, but Eldoreydo Mining takes deliberate steps to minimise the footprint and duration of that disturbance wherever possible. We implement dust suppression programmes on all active haul roads and working areas, using water carts and chemical suppressants as appropriate. Topsoil is stripped and stockpiled before excavation begins and is managed carefully to preserve its biological quality for later rehabilitation use. Stormwater management systems — including sediment dams and diversion drains — are constructed around all active excavation areas to prevent sediment runoff into natural watercourses. Progressive rehabilitation of completed areas begins as soon as excavation activity moves on.
