- Due to a lack of silver outside Pinion in Nevada, consolidated silver Reserves and Resources are reported without a silver grade (N/A) to avoid reporting erroneous average silver grade.
- The Mineral Reserves and Resources estimate has been updated from the 2022 Report to account for depletion from mining operations at the Camino Rojo Oxide Mine and for current gold and silver price and costs.
The Mineral Reserve and Mineral Resource estimates reported on this website were prepared in accordance with Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”), as required by Canadian securities regulatory authorities.
