WEALTH REPORTS INITIAL BATHYMETRIC DATA FROM LAGUNA VERDE LITHIUM PROJECT, CHILE. EXPANDS WORK PROGRAM TO EXPLORE CONVENTIONAL BRINE POTENTIAL AT DEPTH

Wealth Minerals Ltd. has received preliminary data from the bathymetric survey being conducted at the Laguna Verde lithium project in Chile in connection with its previously announced lake-brine sampling and project evaluation program (see news release dated March 31, 2017).

New bathymetric data

The company has received preliminary results from the contractor it has engaged to conduct the bathymetric survey at Laguna Verde. These data show that the maximum depth of the lake is approximately 6.0 metres with a mean depth of approximately 3.5 m. Company representatives have completed a site visit to verify the new bathymetric data and have found the data to be accurate. Previous operators at Laguna Verde reported that the lake was up to 60 m in depth with a mean depth of 33 m, and these data were included in a National Instrument 43-101 technical report dated May 5, 2010, and prepared for Pan American Lithium Corp. The data were referenced by the company in news releases dated Dec. 19, 2016, and March 31, 2017.

Water sampling has begun on the project, and samples will be dispatched to the Tenova Advanced Technologies (a division of Tenova SpA) laboratory for analysis as soon as sampling has been completed, including a 50-litre lake-brine sample.

Conventional brine exploration

Publicly available geophysical and geological data have been acquired by the company, which has allowed the company to define a conventional lithium brine target, similar to the company's exploration target at the Atacama project, underlying Laguna Verde. The data were collected for Barrick and Kinross and filed in December, 2010, as part of an environmental impact assessment (EIA) for an unrelated mineral project. The EIA and its data cover two regional drainage basins and include Wealth's Laguna Verde project. The data of interest are a gravity survey and the resulting geological section, both of which traverse the Laguna Verde property.

Gravity survey data

The gravity profile was collected by a Chilean geophysical consulting company called Geodatos SAIC and reported in September, 2010. The purpose of the survey was to determine the depth to basement, and the accuracy of modelled results was improved by using measured densities from drill core collected within the study area. This approach is understood to result in the best-possible accuracy of the gravity models.

A total of seven gravity profiles were collected as part of the greater survey, and the profile, which traverses the Laguna Verde project, was completed with 37 measurement stations. All details of the survey, including equipment used, survey specifications, data processing and modelling, are included in the detailed EIA report.

Geological interpretation

The geological cross-sections were prepared by SRK Consulting as part of the same EIA project. The geological interpretation utilizes a variety of information, including geological mapping at surface and the gravity data interpretation described above. The geological cross-section transects Wealth's Laguna Verde project. The interpreted section suggests that approximately 500 metres of basin fill exists underlying the current footprint of Laguna Verde, comprising recent sediments such as sand, gravel, clastic sediments and felsic volcanic material, all capped by a layer of ignimbrite (pumice-dominated pyroclastic flow).

Implications

The results of the bathymetric survey at Laguna Verde demonstrate that the lake is considerably shallower than reported in the 2010 report. While this new information reduces the potential lithium brine resource that can be defined within surface lake brine, other publicly available geophysical and geological information opens up a new conventional brine exploration target in the basin-filling sediments underlying the lake. This target type is similar to the company's exploration target at the Atacama lithium project, where aquifer-hosted brines are being targeted in the sediments underlying the property. The existence of surface lake brines, together with potential aquifer-hosted brines at depth, expands the total scope of the project and the exploration work that may be completed thereon.

Expanded work program

The Laguna Verde work program will now be expanded to include geophysical surveys to evaluate the potential for a thick basin fill underlying Laguna Verde and the potential for those sediments to host lithium brines. Additional gravity surveying will be combined with a transient electromagnetic (TEM) survey. Both surveys will begin as soon as possible in second quarter. Assuming that geophysical results justify continued work, drilling will be required to test for the existence of underlying lithium brines. Preparation of a National Instrument 43-101 technical report for the company regarding the project will be delayed to include the results of work on both surface lake brines and underlying conventional aquifer brines.
