1. Production refers to contained metal in concentrate.
2. On-site costs include mining, milling and G&A costs, and include the impact of capitalized stripping.
3. Cash cost and sustaining cash cost are reported net of by-product credits, are calculated at reserve prices ($3.00/lb Cu, $11.00/lb Mo, $18.00/oz Ag, $1,260/oz Au) and include the impact of the precious metals
stream and capitalized stripping. Cash cost includes on-site and off-site costs, and sustaining cash cost includes the addition of royalties and sustaining capital, but excludes Pampacancha project capital.
