Porcher Island drilling returned an interval grading 5.51 grams per tonne of gold over 5 metres, Imperial Metals said on October 28, 2026, reporting results from its spring program in British Columbia.
Key Takeaways
- All 10 drill holes intersected gold and silver mineralization, Imperial said.
- The 5-metre interval was part of a wider intersection in the Christmas Tree zone.
- Imperial plans to use the results to guide further exploration and consider ore sorting.
Porcher Island drilling results
Imperial completed 10 diamond drill holes totaling 1,380 metres from four helicopter-supported pads. The property is about 35 kilometres south-southwest of Prince Rupert.
The strongest reported intersection came from hole PI-26-10, which tested the northern extension of the Christmas Tree zone. It returned 45.5 metres grading 1.24 grams per tonne of gold, including the higher-grade 5-metre interval.
The reported intervals are downhole widths, not confirmed true widths. Imperial said there was insufficient geological information to establish the true width of the mineralization.
| Item | Details |
|---|---|
| PI-26-10 | 45.5 metres at 1.24 g/t gold, including 5.0 metres at 5.51 g/t |
| PI-26-02 | 4.5 metres at 4.77 g/t gold from 75.5 metres downhole |
| PI-26-08 | 2.3 metres at 3.63 g/t gold from 12.0 metres downhole |
Property history and ownership
The property hosts the former Edye Pass and Surf Point gold mines, which operated from 1919 to 1939. Imperial estimates historic production from the two mines at 77,952 tons grading 0.29 ounces of gold per ton.
Imperial’s exploration overview lists Porcher Island as a past producer with a historic resource and describes the company’s interest as 35%. The October drilling announcement instead says Imperial owns 100% of the property; the difference is unresolved.
Further exploration and testing
Imperial plans to incorporate the results into its project database to help plan additional exploration. It also intends to complete ore-sorting test work to assess the potential for direct ore shipping; the announcement did not give a timetable.
