Lavras Gold Corp. Intersects 1.1 g/t Gold Over 154 Metres from Surface at Butiá Gold Deposit, LDS Project, Southern Brazil & Provides an Exploration Update

 

 

 

 

 

Lavras Gold Corp. (TSX-V:LGC) (OTCQX:LGCFF) is pleased to release the results from nine (9) new drill holes testing the Butiá Gold Deposit, located at the western edge of the LDS project in southern Brazil. Gold mineralization was intersected in all nine holes at the Butiá Deposit, which hosts a NI43-101 compliant measured, indicated and inferred gold resource of approximately 0.5 million ounces. Several of these new holes were designed to increase the confidence in the Butiá resource (converting the Inferred Resource into the Measured & Indicated categories) and others to potentially increase the gold endowment as explained below. These new results continue to move Lavras Gold toward its short-term corporate goal of defining an economically feasible gold resource on the LDS Project, focused on the Butiá gold deposit and the adjacent Fazenda do Posto gold target.

Regional Exploration Program – Soil Survey Results

Three significant gold-in-soils anomalies at the following targets:

  • A 3.8 km by 3.2 km anomaly centered over the Matilde and Matilde Extension targets in the southern portion of the property,
  • A 4.6 km by 4.8 km anomaly overlying historical gold workings including Galvao, Zeca Souza and Caneleira, along the western and central western portion of the Lavras do Sul Intrusive Complex,
  • A more scattered anomaly centred along the eastern flank of the Lavras do Sul Intrusive Complex and overlying volcanic rocks (roughly 4 km by 3.7 km)

 

“The new drilling results demonstrate the excellent near-surface gold grade and continuity of the Butiá gold deposit. Results like these have the potential to materially enhance the economics of a near-surface bulk tonnage open-pit type of gold project,” commented Lavras Gold President & CEO Michael Durose. “We are also working to increase the gold endowment at Butiá by relogging and selectively re-assaying the 78 historic drill holes (20,000 metres). The purpose of this initiative is to reinterpret historical results and standardize the geological interpretation and assay results of the data, consistent with new information and geological observations from the adjacent Fazenda do Posto gold discovery. In this way possible new extensions to known gold mineralization can be tested. The results from the regional geochemical (soil) surveys and airborne magnetic survey programs, combined with surface exploration work, will help us select and prioritize future drilling targets as we strive to unlock the full exploration potential of the LDS Property.

 

“An update of drilling results for the recently discovered Fazenda do Posto target is expected as soon as final assay results are received and the geological interpretation is completed. Drilling is on-going in this area.”

Discussion of Drill Results – Butiá Deposit

 

Butiá is the most advanced gold deposit on the LDS property consisting of approximately 0.5 million ounces of gold, located 150 metres east of the recent Fazenda do Posto gold discovery. The purpose of the current drilling program at Butiá is to increase the geological confidence of the existing gold resource by converting a significant portion of inferred geological resources into the measured and indicated categories and to increase the gold endowment of the existing gold resource. Approximately 23.3% of the existing resource estimate is in the Inferred category and the remaining 76.7% in the measured and indicated categories.

 

Since 2005, a total of 78 drill holes for 20,000 meters have been completed at the Butiá gold deposit. An additional nine new drill holes totalling 2,500 metres bring the total number of holes drilled at Butiá to 87 (22,500 metres of drilling). Drill hole lengths from the current program typically range from 160.0 metres to 360.0 metres and have been completed as part of a program of 16 drill holes planned for this area. Details of the locations of the new drill holes relative to existing resource categories can be found in the plan view in Figure 1. A cross-section facing west is shown in Figure 2. Table 1 summarizes assay results. Table 2 tabulates drill hole information including collar coordinates and drill hole depths.

 

Drilling has defined the Butiá gold mineralization over a northwest-southeast strike length of approximately 375 metres, a northeast-southwest strike length of 345 metres and from surface to a depth of 350 metres. The deposit is open to possible expansion in several directions. Generally, long continuous intervals of gold mineralization containing higher-grade subintervals were encountered. The host rocks are extensively hydrothermally altered, and gold is typically hosted in disseminated sulphide minerals (pyrite +- arsenian pyrite) within episyenite host rock or mineralized perthitic granite. Occasional visible gold has been observed associated with sulphide minerals (galena, pyrite) (See Figure 3). The mineralization is bulk tonnage in its nature.

 

Drill hole 23BT016 was collared in the central portion of the Butiá gold deposit slightly southwest of the measured portion of the gold resource (see Figure 1). The hole was drilled at an inclined angle of 60 degrees on an azimuth of 200 degrees. The purpose was to provide a scissor hole to 23BT012 and to test for gold grade continuity through this portion of the deposit. The hole was also designed to extend the measured category of the mineral resource to the southwest. A long interval of continuous bulk-tonnage disseminated gold mineralization was encountered from surface to a depth of 154.0 metres within mineralized episyenite as detailed below.

  • Intersected 154.0 metres grading 1.1 g/t gold from surface (0.0 metres) and including:
    • 109.00 metres grading 1.4 g/t gold from surface (0.0 metres)
    • 29.0 metres grading 2.9 g/t gold from 25.0 metres, and
    • 5.0 metres grading 4.7 g/t gold from 29.0 metres
    • 18.0 metres grading 3.2 g/t gold from 30.0 metres, and
  • 16.00 metres grading 1.0 g/t gold from 208.00 metres and including:
    • 6.00 metres grading 2.1 g/t gold from 208.00 metres

 

Drillhole 23BT012 was collared in the southwest portion of the Butiá gold deposit and drilled on an azimuth of 020 degrees at an inclined angle of 60 degrees (see Figure 1). The purpose was to better understand the nature and continuity of gold mineralization in this portion of the deposit. Continuous gold mineralization was encountered over long intervals in episyenite and mineralized perthitic granite. Higher-grade intervals have been observed within zones of episyenite hosting galena, pyrite and arsenian pyrite (see Figure 4). A summary of assay composites is as follows:

  • 110.0 metres grading 0.7 g/t gold from 136.0 metres including:
    • 5.0 metres grading 1.3 g/t gold from 142.0 metres
    • 2.0 metres grading 2.7 g/t gold from 142.0 metres
    • 20.0 metres grading 1.6 g/t gold from 154.0 metres
    • 3.0 metres grading 4.2 g/t gold from 154.0 metres
    • 3.0 metres grading 6.1 g/t gold from 163.0 metres
    • 3.0 metres grading 2.8 g/t gold from 179.0 metres
    • 2.0 metres grading 4.1 g/t gold from 191.0 metres

 

Drillhole 23BT013 was positioned in the central portion of the Butiá gold deposit, slightly south of the currently interpreted measured portion of the gold resource and drilled vertically (see Figure 1 & Figure 2). The purpose was to better understand the nature of the geology and mineralization in this portion of the deposit. A continuous bulk-tonnage and disseminated style of mineralization consisting mainly of disseminated pyrite +- arsenian pyrite within episyenite occurred from 119.0 metres over a length of 73.0 metres. This included several higher-grade subintervals as detailed below:

  • 73.0 metres grading 0.7 g/t gold from 119.0 metres including:
    • 35.0 metres grading 1.2 g/t gold from 136.0 metres
    • 12.0 metres grading 1.6 g/t gold from 146.0 metres
    • 3.0 metres grading 2.2 g/t gold from 146.0 metres

 

Drillhole 23BT009 was collared along the southwest edge of the Butiá mineralized footprint and drilled on an azimuth of 020 degrees and inclined 60 degrees (see Figure 1). The purpose was to test the southwestern extension of the deposit. Several long intervals of disseminated moderate grade gold mineralization were encountered and including multiple higher-grade subintervals as follows:

  • 16.0 metres grading 0.6 g/t gold from 73.0 metres including:
    • 7.0 metres grading 1.1 g/t gold from 74.0 metres
  • 65.0 metres grading 0.5 g/t gold from 121.0 metres and including:
    • 18.2 metres grading 1.0 g/t gold from 141.0 metres and
    • 8.0 metres grading 1.5 g/t gold from 141.0 metres, and
    • 3.0 metres grading 2.1 g/t gold from 142.0 metres, and
    • 4.0 metres grading 1.3 g/t gold from 168.0 metres
    • 2.0 metres grading 1.2 g/t gold from 208.0 metres
    • 5.0 metres grading 1.5 g/t gold from 214.0 metres

 

Regional Exploration Targeting Program

 

The regional exploration potential on the property is significant as evidenced by recent results generated by the regional soil geochemistry and airborne drone magnetics surveys (see Figure 5 & Figure 6). There are at least 24 known significant gold and gold-copper showings scattered throughout the 22,000-hectare LDS property. Figure 5 highlights that at least three substantial gold-in-soil anomalies have recently been outlined by the regional soil survey program including:

  1. A 3.8 km east-west by 3.2 km north-south gold in soil anomaly centered over the Matilde and Matilde Extension targets in the southern portion of the property.
  2. A 4.6 km northeast-southwest by 4.8 km northwest-southeast gold-in-soil anomaly overlying historical gold workings along the central western portion of the property that covers several gold targets and showings including Butiá, Galvao, Caneleira, Zeca Souza, Caneleira Norte and Paredão among others.
  3. A more scattered gold-in-soil anomaly centred along the eastern portion of the property area along the flank of the Lavras do Sul Intrusive Complex and overlying volcanic rocks measuring about 4 km in a north south direction, and up to 3.7 km in a southeast-northwest direction. Several gold and gold copper showings exist in this area including Dourada, Aurora, Cerro Rico and Mato Feio among others.

 

The near-term priority is to develop new drilling targets using the regional soil and geophysics program as a guide to ground follow-up. Ground follow-up will include detailed geological mapping, sampling, trenching and selective augur drilling of favourable targets. The initial priority area will be in the region of the large gold in soil anomaly along the central western portion of the LDS property north of Fazenda do Posto and Butiá.

 

These extensive gold-in-soil anomalies, when superimposed on regional magnetics (See Figure 6), point to a complex structural setting where gold anomalies and historical workings appear to be centred on magnetic low structures. This is certainly the case at the Caneleira gold target, where a kilometer-scale east-west gold-bearing structure has been defined in previous drilling. The best historical drill hole intersection was 1.4 g/t gold over 36.1 metres approximately 70 metres down the drill core. These regional surveys, combined with surface exploration work, will inform the selection and priority order for future exploration drilling targets as the Lavras team strives to unlock the full exploration potential of the LDS Property.

 

2024 Exploration Program Overview & Objectives

 

Lavras Gold’s short-term corporate objective is to define an economic gold resource on the LDS Project with a focus on the Butiá gold deposit and adjacent Fazenda do Posto gold target. A 25,000-metre diamond drilling contract has been signed with GeoSol, a Brazilian drilling company. The current drilling program consists of two diamond drill rigs that are now on site and designed to test exploration targets continuously from now until the first half of 2025. This drilling program is in addition to the 20,000 metres of drilling completed by the company since it went public in April 2022, and the more than 60,000 metres of historical drilling on the property by previous operators. Approximately 10,000 metres of drilling have currently been budgeted to test Butiá and Fazenda do Posto. Further drilling of these targets may happen as results warrant. Drilling of other exploration targets is anticipated in the second half of 2024 with the objective of discovering new economic gold deposits on the LDS property.
