Macarthur Minerals Update

 

Cadence Minerals Plc (AIM/NEX: KDNC; OTC: KDNCY) is pleased to report that Macarthur Minerals ("Macarthur" or the "Company") in which Cadence currently owns a 20.3% shareholding, has announced that it has expanded its lithium brine project portfolio, staking the Reynolds Springs Lithium Brine Project in Nevada on which it has located lithium at surface of up to 300 parts per million ("ppm") lithium ("Li").

The full Macarthur announcement can be found at: https://web.tmxmoney.com/article.php?newsid=8088271344476834&qm_symbol=MMS .

The Company has staked 210 new unpatented placer mining claims at its new Reynolds Springs Lithium Brine Project ("Reynolds Springs Project") in the Railroad Valley, Nevada. Three surface samples at the Reynolds Springs Project returned 260 to 300 ppm Li.

 

Reynolds Springs Project - Geological Setting

The new claims are located near the town of Currant, in Nye County, Nevada. The Reynolds Springs Project is located approximately 180 miles (300 km) North of Las Vegas, Nevada, and 330 miles (531 km) South East of Tesla's new Gigafactory.

Railroad Valley is a large topographically closed playa (dry Salt Lake bed) basin located in East-central Nevada. The basin is fault bounded with numerous active thermal springs (anomalous in lithium) emerging along the faults. The fault sets have strike lengths of 25 - 30 miles (42 - 50 km) and are parallel to each other, about 8-12 miles apart. The faults that bound the basin form an elongate rectangular shaped basin of about 300 square miles (830 square km) in size.

Numerous thermal springs emerge along the basin bounding fault systems which form the North-West and South-East flanks of the playa basin. Thermal waters which discharge from the springs carry moderately anomalous values of Lithium. Water samples collected from Reynolds Springs by Macarthur Minerals' consulting geologists averaged 230 parts per billion ("ppb") Li and 445 ppb boron. This about twice the concentration for these elements detected from water samples collected at other springs that were sampled in the valley.

The mountains that surround the basin contain outcropping rock units are also anomalous in lithium. This closely matches the geologic criteria for the United State Geological Survey ("USGS") deposit model for Clayton Valley type lithium brine deposits. Macarthur Minerals believes that the combination of anomalous lithium in soils (+250 ppm) and anomalous lithium in thermal spring waters (230 ppb Li) indicates that the Reynolds Springs Project area is favorable for further exploration.

 

Historical Data

Prior to staking the claims, Macarthur Minerals completed an analysis of USGS historical soil, rock and groundwater data collected across California, Nevada and Utah. Sediment samples collected in the 1980s, during the United States Department of Energy's National Uranium Resource Evaluation Program ("NURE") were of particular interest. Spatial analysis of the historical data shows Railroad Valley to be the largest lithium soil anomaly in the State of Nevada. A total of 19,165 soils samples were collected by NURE across Nevada and analysed for Uranium, Lithium and other elements. Eighty-seven (87) samples returned lithium values in excess of 100 ppm. A cluster of 20 samples greater than 100 ppm were collected from Railroad Valley.

The other area identified from the NURE dataset that had similar elevated lithium levels was the Clayton Valley which hosts North America's only producing lithium mine, Albemarle's Silver Peak Lithium Mine. In comparison, approximately 108 samples were collected from the Clayton Valley and surrounding the Silver Peak mine. A total of nine samples reported assays greater than 100 ppm with samples ranging from 102 to 431 ppm Li.

 

Reconnaissance soil sampling in the Railroad Valley by Macarthur Minerals' consulting geologists narrowed the area of interest to the Reynolds Springs area on the North-West flank of the playa basin.  A total of five widely spaced reconnaissance soil samples were collected from the Reynolds Springs area.  Analysis of these samples by ALS Chemex Labs using the ME - ICP41 and ICP61 methods returned a range of values for the five samples ranging from 80 - 350 ppm Li (average 256 ppm Li) and a range of 20 - 720 ppm B (average 342 ppm Boron).

The water and soil sample results mentioned above were compared to results from other reconnaissance samples collected elsewhere in the Railroad Valley.  This demonstrated that the Reynolds Springs area appeared to be enriched in lithium.  As a result of that analysis, a total of 210 new 20-acre unpatented placer mining claims were staked as indicated in Figure 1. 

 

Next Steps for the Reynolds Springs Project

The Company has recently completed a 210 point geochemical soils sampling program across the Reynolds Springs Project (concurrent with the claim staking). Samples have been submitted to the laboratory for assay and will be reported when data is available. Following analysis of this wide spaced sampling program, the Company will consider an infill sampling program across areas considered highly prospective for lithium.

Macarthur Minerals is also currently undertaking a review of hyperspectral ASTER satellite imagery of Railroad Valley to identify additional prospective areas.

The Reynolds Spring Project is located only 110 miles (183kms) from the Company's Stonewall Project in the Lida Valley, Nevada. The close location of the Reynolds Springs Project and Stonewall Project will allow sharing of resources and expertise for exploration of both projects. The Company is considering entering into joint ventures to assist in the exploration of both projects.

About Cadence Minerals:

Cadence is dedicated to smart investments for a greener world. The planet needs rechargeable batteries on a global scale - upcoming supersized passenger vehicles, lorries and buses - require lithium and other technology minerals to power their cells. Cadence is helping find these minerals in new places and extracting them in new ways, which will meet the demand of this burgeoning market. With over £40 million vested in key assets globally, Cadence is helping us reach tomorrow, today.

Cadence invests across the globe, principally in lithium mining projects. Its primary strategy is taking significant economic stakes in upstream exploration and development assets within strategic metals. We identify assets that have strategic cost advantages that are not replicable, with the aim of achieving lower quartile production costs. The combination of this approach and seeking value opportunities allows us to identify projects capable of achieving high rates of return.

The Cadence board has a blend of mining, commodity investing, fund management and deal structuring knowledge and experience, that is supported by access to key marketing, political and industry contacts. These resources are leveraged not only in our investment decisions but also in continuing support of our investments, whether it be increasing market awareness of an asset, or advising on product mix or path to production. Cadence Mineral's goal is to assist management to rapidly develop the project up the value curve and deliver excellent returns on its investments.
