1. | Intersection assays are a composite of one-metre assays calculated from interval-weighted assays over a minimum three metre intersection length using a 2.0 g/t gold cut-off. A maximum of three metres of waste or lower grade material also may be included in the composite. | |
2. | No high assay values have been cut. |
|
3. | Interval widths generally are equivalent to true widths. |

1. | Intersection assays are a composite of one-metre assays calculated from interval-weighted assays over a minimum three-metre intersection length using a 2.0 g/t gold cut-off. A maximum of three metres of waste or lower grade material may also be included in the composite. | |
2. | The included intervals (includes) are significantly higher in tenor and exceed 15.0 g/t gold within the 2.0 g/t gold cut-off intervals. | |
3. | No high assay values have been cut. | |
4. | Interval widths generally are equivalent to true widths. | |
5. | The following recently assayed holes did not intersect significant mineralization: |
