SnapshotThe Parral operation is an agglomerated heap leach facility which is processing historic tailings.

The Parral Project comprises dry land tailings deposited from the historical Mina la Prieta silver and base metal mine. The tailings were deposited in two separate areas.

The principal products under production are precious metals, primarily silver and gold.

As part of environmental management strategy, GoGold has incorporated technology that minimizes impacts on air quality. The installation of the SART Plant (Sulfidization, Acidification, Cyanide Recirculation and Copper Precipitate Thickening) for copper and zinc sulfide recovery, in addition to cyanide regeneration, is a relevant environmental remediation measure.

Improved water storage and reuse system at Parral achieved over 95% recycling efficiency and resulting in decrease of 5% in water usage in FY2025 compared to the prior year.

Summary:

The Parral mining district is situated in the centre of the Mexican silver belt epithermal silver-gold vein districts. The geology of this belt is characterized by two volcanic sequences of Tertiary age, discordantly overlying deeply eroded Mesozoic sediments and older metamorphic rocks. The physiography of the belt resembles the basin and range area in the western USA, with wide, flat valleys and narrow, relatively low mountain ranges and hills.

The precious metal-bearing fissure vein type of mineral deposit is the most widespread and economically important type of deposit found in the belt. The belt has been recognized as a significant metallogenic province, which has reportedly produced more silver than any other equivalent area in the world.

Mineralization
Tailings from the Mina la Prieta mill were impounded on dry ground to the north of the mine and milling complex. The tailings were deposited over many years in flat, consistent layers, dewatered and eventually built up in 5 m lifts into raised heaps reaching a final height of 50 m. The physical consistency of the material is uniform and has an average particle size distribution of 80% passing 0.255 mm.
