The drilling, completed between April and June, has provided evidence for more gold to be recovered with headline intercepts such as 8.7m at 129 grams per tonne and 8.5m at 32.7gpt from Darwin South, 3.3m at 42.1gpt from Zone 96, and 5.6m at 12.9gpt from Mt Julia.
The results are being collated, and a resource and reserves update is due this month.
A new life-of-mine plan is also being prepared, with Catalyst keen to leverage off the existing infrastructure and 300,000tpa mill to restore production to 35,000 ounces per annum by June 2023.
The plant can support that rate with no further investment needed.
Technical director Bruce Kay said the company remains confident in the upside given it was outlining more high-grade mineralisation in multiple areas.
The company set a A$7 million exploration budget for 2022-23, from available cash of $21 million.
The miner secured the operation in early 2021, and increased FY22 production to 25,199oz.
Henty has resources of 357,000oz at 4.4gpt.
An exploration target for the recently defined Cradle Zone discovery is also being prepared.
