Lundin Gold Provides Update On Regional Exploration Drilling
VANCOUVER, Feb. 16, 2022 - Lundin Gold Inc. (TSX: LUG) (Nasdaq Stockholm: LUG) ("Lundin Gold" or the "Company) is pleased to provide an update on the completed 2021 regional exploration drilling program of the Suarez pull-apart basin ("the Basin") and a preview of the 2022 program, which is now underway. The Basin is interpreted to be a 16 kilometre-long geological structure trending south from Fruta del Norte, the Company's high grade operating gold mine in south-eastern Ecuador. PDF version.
Ron Hochstein, President and CEO commented, "The 2021 program continued to support and further strengthen our position that buried Fruta del Norte style deposits occur within the southern Basin. Exploration of the southern Basin has been challenging due to the topography and the thickness of the cover rocks, with this part of the Basin being roughly 20 km2 in area and mostly covered by post-mineral lithologies. With the results of the 2021 program, the 2022 program is underway and will continue to evaluate further south along both margins of the Basin."
2021 Program
Two target areas were drilled for a total of 11,136 m in 2021: the Barbasco anomaly along the eastern margin of the Basin, and Puente-Princesa along the western Basin margin (see Figure 1). While drilling in 2021 only intersected relatively narrow, low grade vein mineralization, the drilling has been very encouraging as it has confirmed that gold-bearing hydrothermal fluids circulated in the southern Basin at the same time as Fruta del Norte was forming further north. The program has advanced the Company's understanding of the southern Basin and provided direction for the 2022 program, which will move into completely covered areas with the aim of locating areas where mineralizing fluid flow was more focused.
At Barbasco, 5,387 m were completed in six drill holes (see Tables 1 and 2 for Barbasco drilling information). Drilling at the target intersected zones of epithermal related alteration and multiple narrow (< 2 m wide), widely spaced epithermal quartz-carbonate-sulphide veins in the Santiago Formation (the host rock of Fruta del Norte), andesites and sediments. Most of the veins are anomalous in gold and silver and the epithermal pathfinder elements arsenic and antimony. In the overlying Suarez (basin fill) sediments, broad intervals of marcasite alteration with epithermal pathfinder geochemistry were intersected. The veining and alteration increase to the south, with the interpretation that there is a component of lateral flow from this direction.
At Puente-Princesa, a total of 5,749 m was drilled in six holes (see Tables 1 and 3 for Puente Princesa drilling information). Initial interpretations of the results are as follows:
- Drilling intersected a thick sequence of cover rocks, followed by Santiago Formation that was often hydrothermally altered and brecciated. Broad zones of the Santiago Formation are anomalous in the key epithermal pathfinder elements arsenic and antimony, but only narrow and low-grade gold intervals were intersected, with a best intercept of 10 m at 0.46 g/t Au.
- Mineralized (epithermal) clasts associated with some assay grades in the Suarez conglomerate were found but contain less epithermal marcasite than Barbasco, with the interpretation that the mineralization in this part of the Basin is part of an earlier (early or pre-basin) epithermal system.
2022 Program
The aim of the 2022 program is to find buried "Fruta del Norte" type epithermal gold-silver systems in the southern Basin. Using the alteration and epithermal pathfinder geochemistry of the Suarez sediment as a vector, exploration drilling is now focussed on areas completely covered by post-mineral rocks.
The Barbasco south area has been prioritized as a target area with access track and drill platform construction underway. This untested part of the Basin margin is approximately 3 km long, is completely covered and is upslope from the Puma surface epithermal clasts (of unknown origin) (see Figure 1 for location of Puma target area).
At the Puente-Princesa target, drilling is underway, with two drill rigs currently turning, testing for buried mineralization along the western Basin margin.
Background
The Basin has similar lithologies, alteration, geochemistry and structure to that around the Fruta del Norte deposit at its northern end. Significantly, there are very large areas of epithermal related marcasite alteration, highly anomalous in the epithermal pathfinder elements arsenic and antimony within the Basin sediments. This is interpreted to have originated from epithermal systems that discharged fluid into the Basin and is a distinct feature around the Fruta del Norte deposit. Although surface exposures of this alteration in the southern Basin are limited by the cover rocks, drilling at Puma (in 2017/18) and Barbasco (2021) has delineated very extensive areas of epithermal marcasite. Formed in unconsolidated sediment during the Jurassic period, this alteration has a component of lateral flow from the source epithermal system.
