Fazenda do Posto Discovery

A globally significant gold discovery

On August 29, 2023, Lavras Gold announced a new discovery at Fazenda do Posto immediately to the west of the Butiá Gold Deposit in an area of recessive topography (lower than the surrounding area) in the LDS intrusive-hosted gold system. The assay results showed remarkably continuous mineralization of 340 metres grading 1.1 g/t gold from 116 metres including:

• 160 metres grading 1.8 g/t gold from 199 metres including
  • 27 metres grading 2.1 g/t gold from 208 metres
  • 68 metres grading 2.1g/t gold from 293 metres.

Additional drilling results from Fazenda do Posto validated the discovery in terms of gold grades, widths and continuity and remains open in several directions to resource expansion. Results from 2023, 2024 and 2025 included:

• 251 metres grading 1.2g/t gold from 208 metres including:
  • 100.0 metres grading 2.2 g/t gold from 214.0 metres, and including
  • 20.0 metres grading 2.4 g/t gold from 233.0 metres, and
  • 10.0 metres grading 2.7 g/t gold from 259.0 metres, and
  • 25.0 metres grading 2.9 g/t gold from 276.0 metres, and
  • 10 metres grading 4.6 g/t gold from 304.0 metres
• 204 metres grading 1.0 g/t gold from 31 metres including:
  • 65 metres grading 1.9 g/t gold from 149 metres; and including
  • 10 metres grading 3.0 g/t gold from 154 metres.
• 173.0 metres grading 1.0 g/t gold from 69.0 metres and including:
  • 2.0 metres grading 2.1 g/t gold from 99.0 metres
  • 94.8 metres grading 1.4 g/t gold from 126.0 metres (about 109.0 metres vertical)
• 59.0 metres grading 2.9 g/t gold from 233.0 metres, and including:
  • 50.0 metres grading 3.2 g/t gold from 238.0 metres, and including
  • 32.0 metres grading 4.3 g/t gold from 240.0 metres, and including
  • 3.0 metres grading 17.6 g/t gold from 253.0 metres, and including
  • 1.0 metre grading 9.6 g/t gold from 253.0 metres, and including
  • 1.0 metre grading 23.3 g/t gold from 254.0 metres, and including
  • 1.0 metre grading 30.3 g/t gold from 255.0 metres.

Fazenda do Posto demonstrates very good continuity and gold grade at depth as well as laterally, where it remains open in several directions. Results such as these have the potential to materially enhance the economics of a combined Butiá-Fazenda do Posto near-surface bulk tonnage open-pit type of gold project. Butiá extends to depths of greater than 300 metres, while Fazenda do Posto extends to more than 400 metres.

While the entire 340 metre interval of the discovery hole is gold mineralized, it is also significant that there are long intervals of consistent higher-grade gold above 2 g/t. When some of the lower grade intervals are removed from this intercept, this hole returned 269 metres grading 1.35 g/t gold of mineralized material. These higher-grade intervals suggest the hole could be tracking toward a feeder structure. Continued exploration will be undertaken to confirm this.

This area was chosen as a drilling target after the Lavras geological team, when reviewing the data from Butiá, noticed there was a fault on its west side in an area of recessive (sunken) topography. They hypothesized that there might be some alteration causing this topographically low area. Soil survey results showed no surface expression of gold mineralization across this low area, however, the decision was made to drill to test the underlaying cause of the topographic low.  It was the second hole drilled at Fazenda do Posto that returned the 340 metres of 1.1g/t gold, sitting below a mostly barren caprock, which masked any surface expression. This opens a whole avenue of exploration – areas which have no surface expression of mineralization, hidden under unmineralized cover rock.

The Butiá–Fazenda do Posto area is a priority focus for Lavras Gold.
