The new layout design was reassessed in terms of gravitational flow. The layout of the extraction level for 4 of the 6 Central Macroblocks (MB) (mixed 16x16 and 16x20 mesh) was reevaluated

An Esmeralda back-analysis was performed to evaluate the recovery from the layouts used.
FlowSim was calibrated with the Esmeralda data to be used in the Diamante Project.
Drilling was recommended in accordance with the FlowSim remnant model.

The recovery of fine copper was evaluated for different options of extraction layouts. The Esmeralda remnant block model developed in FlowSim was validated against the Diamante block model.

PC1 and PC2 were simulated to evaluate mining extraction and recovery.
The ore grade extracted was predicted with less than 6% error for Au and less than 4% for Cu.
Calibration was based on the markers extracted in far and near field tests, obtaining good correlation in terms of horizontal displacements.

PC1 was simulated in FlowSim BC to correlate the type of rock extracted and Hang up & Swell Rill of Fines (HUF & SRF) events; this lithology is then input into BCRisk analysis software. The result predicts future HUF and SRF events with a high degree of accuracy.

Simulations were conducted to evaluate the Caving Monitoring System in the PC2-3 sector. Ore grades and markers extracted were analyzed using FlowSim.

Comprehensive analysis included mining design, the construction sequence, the area incorporated, the production program, and the best point at which to automate based on current capacities and requirements of automation technologies.

Technology developed by ENAEX was evaluated in different scenarios to identify and suggest opportunities for improvement.

Studies of wet muck were carried out in which an operational and detailed evaluation defined its behavior from the point it was emptied into the ore pass to the collection piles.

BCTEC analyzed the main mining operations in Chile, Brazil, Peru, Argentina, Colombia, USA, Mexico, Canada and Australia to determine the market to 2030.

Using information from drilling, a three-dimensional block model was generated to determine rock quality.

Risk analysis was carried out on the main geomechanical hazards for the San Gabriel project, which is currently in the conceptual engineering stage.

Using BCRisk-WME, an analysis was performed to determine the risk of wet muck entry (WME) and the areas most prone to this problem. The analysis also predicted wet-muck behavior over time based on the mine’s long-term plan and particular conditions.

Models were constructed to determine the risk of SRF events using BCRisk-SRF and hang up frequency (BCRisk-HUF) based on the long-term plan of PC1 and PC2 along with the particular conditions of the project.

An analysis was performed to incorporate operational variables in the risk assessment of SRF events to be used in short-term planning (BCRisk-SRF-ST).

Esmeralda mine back-analysis was carried out to prepare a mathematical model to evaluate the extended long-term plan and determine the reserves and recovery.

BCRisk model was built with data from the Esmeralda Mine, which was then used in the Diamante Project. Mine reserves were defined and recommendations made based on the risk of wet muck entry generated by the different extraction strategies.

BCRisk model was built with data from the Esmeralda Mine, which was used in the Andesita Project. Mine reserves were defined and recommendations made based on the risk of wet muck entry generated by the different extraction strategies.
