Calibre Mining Corp. and Alder Resources Inferred Resource (using a 0.15% Copper cutoff grade)
1. Base case is reported at a 0.15% copper equivalent cut-off grade which incorporates consideration of mining
and processing cost, recoveries, commodity prices and selling cost.
2. Estimate assumes a long term copper price of US$2.90/lb, a gold price of US$1,200/oz and a silver price of
US$24/oz.
3. Rounding as required by NI 43-101 reporting guidelines may result in apparent summation differences.
4. Tonnage and grade measurements are in metric units. Contained gold and silver ounces are reported as troy
ounces, contained copper pounds as imperial pounds.
5. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The estimate of
mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical,
marketing, or other relevant issues.
6. The quantity and grade of reported inferred mineral resources in this estimation are uncertain in nature and
there has been insufficient exploration to define these inferred mineral resources as indicated or measured
mineral resources and it is uncertain if further exploration will result in upgrading them to indicated or measured
mineral resources.
