Zenith Minerals (ASX:ZNC) has commenced lithium drilling over a wide area of 2km x 4km at the Zacatecas Lithium Project in Mexico. Drilling will be completed to a depth of 25m, testing the lithium brine systems that have yielded grades up to 2.1% lithium in neighbouring projects in the district. The project is part of the $5m Bradda Head JV.
- An initial near surface drill program has commenced to test beneath highly anomalous results up to 1046ppm lithium in surface sediments over an area 4 km by 2 km on salt pans in the Zacatecas Lithium Project in central Mexico;
- Drilling will test for near surface lithium brines (max 25m depth), and is funded under the previously announced (ASX Release 7th March 2017) US$5 million farm-in deal with prominent UK investor Jim Mellon (Bradda Head Ltd);
- Zenith has previously advised (17th January 2017) brines grading up to 2.1% lithium reported in regional sampling by the Mexican Government from solar evaporation ponds for salt production on an adjacent salt lake (10km west of the Zacatecas Lithium Project).
- These regional water results confirm lithium enriched source brines are present in the district, as well as demonstrating that concentration of lithium by traditional solar evaporation methods is possible;
- First phase geophysical surveys by Zenith using the passive seismic technique confirmed initial interpretation of a sedimentary basin beneath the surface salt lakes;
- Ground based electrical geophysical surveys (depth penetration up to 400m) are now planned for July to assess the project for deeper brine aquifers prior to deeper drill testing later in 2017.
Zenith Minerals Limited (“Zenith” or “the Company”) is pleased to advise that a program of shallow drilling has commenced at the Zacatecas Lithium Project in central Mexico. The program, fully funded by the Bradda Head Ltd under the American Lithium Joint Venture was bought forward as a suitable drill contractor became available in the project area.
The aim of this short hole auger drill program is to provide an initial test for lithium in near surface brines and sediments of the San Juan salt pans where recent systematic, infill sampling returned highly encouraging surface sediment results up to 1046ppm lithium (Figure 1). As previously advised (ASX Release 24th May 2017) the surface sampling program has to date, outlined a large 4km by 2km strong lithium anomaly (values greater than 300ppm lithium) on the San Juan concession (Figure 2).
The drill program will consist of 11 short drill holes (25m maximum hole depth) from which sediment samples will be collected as the hole is drilled. Upon completion of each drill hole slotted casing will be inserted allowing for the sampling of sub-surface brines. Drilling is anticipated to take approximately two weeks, sediment sample assays will be available approximately 3 weeks thereafter, whilst brine analyses will take approximately 4 weeks.
