Hudbay Announces Exploration Agreement for Maria Reyna and Caballito Satellite Properties near Constancia in Peru

TORONTO, Aug. 25, 2022 - Hudbay Minerals Inc. ("Hudbay" or the "company") (TSX, NYSE: HBM) today announced the Uchucarcco community has formally approved an exploration agreement with Hudbay granting surface rights to the Maria Reyna and Caballito satellite properties located near Hudbay's Constancia mine in Peru, as shown in Figure 1. These satellite properties consist of a large, contiguous block of mineral rights held by Hudbay and have the potential to host mineral deposits within trucking distance of the Constancia processing facilities.

"We are very pleased to have reached an exploration agreement with the Uchucarcco community on these highly prospective properties," said Peter Kukielski, Hudbay's President and Chief Executive Officer. "Historic drilling at Maria Reyna indicates attractive grades over wide intersections starting at surface and the past-producing Caballito property has the potential to add higher grade copper mineralization to our Constancia operations. This exploration agreement demonstrates our commitment to partnering with the local communities and we look forward to continuing to work harmoniously with the communities to add value to our long-life operation in Peru."

The company expects to commence early field exploration activities in August and finalization of the Uchucarcco agreement is anticipated to increase community investment costs in the second half of 2022. Hudbay's planned exploration programs at Maria Reyna and Caballito have been prepared using information from the company's geophysics surveys in the region, as shown in Figure 2, and the historical drill intersections at Maria Reyna, as shown in Table 1.

Table 1: Maria Reyna Historical Drill Results

Historical drilling in the Maria Reyna south-west zone completed by a previous owner consisted of 11 diamond drill holes covering a total of 5,585 meters. The historical drill results include 136 metres at 0.61% copper-equivalent ('CuEq"), 106 metres at 0.55% CuEq and 160 metres at 1.03% CuEq. A qualified person has not independently verified this historical data or the quality assurance and quality control program that was applied during the execution of this drill program and, as such, Hudbay cautions that this information should not be relied upon by investors.

Notes:
The intersections represent core length and are not representative of the width of the possible mineralized zone.
For additional information, including drill hole locations and the data verification and quality assurance / quality control carried out by the prior owner, please refer to Management's Discussion and Analysis for Indico Resources Ltd. ("Indico") for the year ended May 31, 2014, as filed by Indico on SEDAR on September 29, 2014.
Intervals were calculated with maximum of 10 metres of 0.1% CuEq internal dilution, 0.2% CuEq edge grade, minimum length of 15 metres. For CuEq calculations the following variables were used: $3.00/lb Cu, $15.00/lb Mo, $21.00/oz Ag; no allowances for metallurgical recoveries were made.
