CAVU Mining Corp. (CSE: CAVU) (OTC: CAVVF) (FSE: 8NQ) is pleased to announce drill results for drill holes HOP21-DDH-04 and -05 on the Hopper copper-gold project in Yukon Territory, located in the traditional territory of the Champagne and Aishihik First Nations.
Highlights Released September 27, 2021
“Copper Castle continues to deliver excellent intersects with skarn mineralization,” stated Jaap Verbaas, CEO of CAVU. “HOP21-DDH-05 intersected 4 different skarn horizons and a short interval of granodiorite with strong potassic alteration. This hole is over 1,000m from the first three drill holes released on September 27 and shows clearly that skarn mineralization continues along strike. The hole also intersected potassically altered granodiorite. This alteration in the granodiorite is significant as it links mineralization in Copper Castle to the Hopper Intrusion, that hosts porphyry-style mineralization. Despite intersecting barren cross-cutting dykes at shallow depths, hole HOP21-DDH-04 intersected two deeper skarn horizons, one with 6.62m at 0.96% CuEq. Taken together with the results of hole HOP21-DDH-01 to -03 we now believe that extending the higher-grade zone to the north and south should be a priority at Copper Castle, prior to extending the disseminated zone to the west of that. We are happy with the results from the drilling of Copper Castle and now look forward to releasing the results from drilling the Hopper porphyry target in a coming news release.”
HOP21-DDH-04 and -05 were targeted at the northern boundary of the Hopper intrusion to characterize skarn mineralization proximal to the intrusion, test the northern limits of the Copper Castle zone, and to gain insight on its relation to the Hopper porphyry target.
Hole HOP21-DDH-04 intersected sheeted barren dykes at the depths where shallow skarn horizons were expected. These sheeted dykes are common in large multi-phase intrusive complexes such as the Hopper intrusion. HOP21-DDH-05 intersected 4 skarn horizons at variable depths and grades.

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).

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. CAVU adds another 5% QAQC samples consisting of standards, blanks and field duplicates. The QAQC samples that return unacceptable values trigger investigations into the results and re-analysis of samples that were tested in the batch with the failed QAQC sample.
Roger Hulstein, P. Geo., is the qualified person for the Company as defined in the National Instrument 43-101 and has reviewed the technical information presented within the news release. On October 1, 2021, Mr. Hulstein was granted 50,000 stock options in the Company, having an exercise price of $0.57 per share and an exercise term of three years.
