CAVU Mining Intersects 22.28m of 1.405 % Cu, 11.7 g/t Ag and 0.532 g/t Au (1.84% CuEq) on Hopper Copper-Gold Project in Yukon






CAVU Mining Corp. (CSE: CAVU) (OTC: CAVVF) (FSE: 8NQ) is pleased to announce drill results for drill holes HOP21-DDH-01 to -03 on the Hopper copper-gold project in Yukon Territory, located in the traditional territory of the Champagne and Aishihik First Nations.




  • Hole HOP21-DDH-01 intersected 22.28m of 1.84% CuEq, consisting of of 1.405% Cu, 11.7 g/t Ag, and 0.532 g/t Au
  • Hole HOP21-DDH-02 intersected 9.39m of 0.78% CuEq, consisting of 0.622% Cu, 4.2 g/t Ag, and 0.197 g/t Au
  • Hole HOP21-DDH-03 intersected 10.96m of 1.76% CuEq, consisting of 1.365% Cu, 9.6 g/t Ag, and 0.488 g/t Au


“These encouraging high-grade drill results indicate that the true extent of Copper Castle is yet unknown as the mineralization remains open to the south, east and west,” stated Jaap Verbaas, CEO of CAVU. “The tenor of mineralization surpassed what we expected and Hole HOP21-DDH-01 contains the longest high-grade true-width intersect drilled on the Hopper Project to date. The holes tested a particular geophysical anomaly which continues further south for several hundred meters and we look forward to drill-testing this anomaly and the mineralization along strike.”

1Drilling approximately directed perpendicular to bedding and skarn horizons, therefore intersects are expected to be within 95% of true width.
2Assumptions used in USD for the copper equivalent calculation were metal prices of $3.00/lb Copper, $1,300/oz Gold, $18/oz Silver and recovery is assumed to be 100% as only preliminary metallurgical test data is available. The following equation was used to calculate copper equivalence: CuEq = Copper (%) + (Gold (g/t) x 0.6319) + (Silver (g/t) x 0.0087).

Copper Castle extension and geophysics


Copper Castle is a skarn zone at the Hopper project of approximately 1350 x 650m in aerial extent. Geological modeling indicates at least 8 skarn horizons from surface to 400m depth. The drill intersects from hole HOP21-DDH-01 to DDH-DDH-03 are from one continues skarn horizon that is characterized by magnetite-chalcopyrite-pyrrhotite skarn to magnetite-carbonate-chalcopyrite skarn.


The drill holes targeted an electromagnetic (EM) anomaly that continues towards the south and north and is largely undrilled. The intersects confirm this anomaly is associated with intense skarnification and massive sulphide mineralization. The correlation of the anomaly to massive sulphide mineralization also supports other untested EM anomalies on the claim.


QAQC and Data Verification


The current drill samples have analyzed by MS Analytical Langley, an ISO 9001:2008 certified laboratory. Quality assurance and control is maintained at the lab through rigorous use of internal standards, blanks and duplicates. An CAVU adds another 5% QAQC samples consisting of standards, blanks and field duplicates. QAQC samples that return unacceptable values trigger investigations into the results and reanalysis of samples that were tested in the batch with the failed QAQC sample.
