Even better news, apparently Nagoya can be high-graded for way more than 2 years by increasing the cutoff grade:

by increasing the cutoff to 1.25 g/ton, the total resource is reduced by 20% to 1.35 million oz at 3.15 g/ton average grade. This is still enough for 8 years of mine life!

The grade tonnage curve for the Namoya In-pit M&I Mineral Resources is illustrated in Figure 2, and demonstrates that the Namoya project can be mined at a significantly higher grade than the Resource grade without impacting significantly on the contained gold. This is based on the fact that if one increases the cut-off from 0.5g/t Au to 1.00g/t Au, grades increase from 2.04g/t Au to 2.79g/t Au, with contained gold reducing by only some 12% and could even be increased above 3.0g/t Au without compromising the mine life significantly. This indicates that high-grading the deposit is a feasible option and mine planning could focus on a higher grade, lower tonnage mine design in times of a falling metal market without destroying the economics of the project. The Namoya In-pit M&I Mineral Resources at the various cut-off grades are summarized in Table 3.
