CAVU Provides Overview of 2021 Drilling on Hopper Copper-Gold Project

CAVU Mining Corp. (CSE: CAVU), is pleased to provide an overview of the 2021 drilling campaign on the Hopper copper-gold project located in the Yukon. The Hopper project is in the traditional territory of the Champagne and Aishihik First Nations.


  • The skarn, now named “Copper Castle”, mineralized footprint expanded from 433,000 m2 to 507,000 m2, a 16% increase
  • Visual inspection indicates mineralized skarn horizons intersected in every hole at Copper Castle
  • Mineralized margin of a porphyry intrusion intersected from surface to 200m depth through testing of three complementary datasets with one hole
  • Drilling results are expected to be returned from MS Analytical Langley soon

The footprint of mineralization at Copper Castle increased by 16%, after CAVU’s inaugural drill campaign. Mineralization at Copper Castle occurs over a strike length of 1350m.The holes targeted skarn extensions, geophysical targets, and undrilled showings. Copper Castle remains open to all directions but the north, where it is cut off by the Hopper intrusion where the Company has discovered porphyry mineralization.

“We are very happy with the results of the drilling on the Hopper,”

stated Jaap Verbaas, CEO of CAVU.

“Despite border restrictions and supply chain issues, which are amplified in Canada’s north, CAVU drilled 1119m in six holes. The first five holes increased the footprint of Copper Castle considerably. The sixth hole intersected the low-grade shell normally found around mineralized porphyry cores. This hole represents a major development on the project as it proves the occurrence of a mineralized porphyry. These holes lay the foundation for a larger program in 2022 during which we will vector towards the center of the porphyry target and further increase the Copper Castle footprint.”

Copper Castle skarn exploration

Five holes were drilled in the Copper Castle skarn in 2021. The holes were designed to test certain geophysical targets such as EM and magnetic targets while at the same time infilling and extending the mineralized envelope. As a result, the mineralized footprint of the skarn increased considerably, and the company expects this will increase further to the south, west and east.

Hopper porphyry exploration

HOP21-DDH-06 was collared in a porphyry target (Figure 2) and designed to test three separate datasets (magnetic, induced polarization,and soil geochemistry). The result identified which datasets are best utilized for targeting shallow porphyry mineralization. The hole intersected chlorite altered (propylitic) monzonite locally cut by vein-controlled potassic alteration and mineralized porphyry dykes. Mineralization includes minor vein-hosted to disseminated chalcopyrite (average <0.3% chalcopyrite from 0 – 200m), the latter overprinting primary mafic sites. Potassic alteration is a marker for high-temperature alteration in porphyry centers. The three intended datasets were successfully tested and give the company a clear strategy for porphyry exploration. The alteration and mineralogy indicates that HOP21-DDH-06 intersected the margin of a Cu-Mo porphyry system, proximal to a porphyry center.
