  • RESULTS CONFIRM EXTENSION to Mcdermitt RESOURCE
    ASX RELEASE 5 March 2021 ASX: JRL RESULTS CONFIRM EXTENSION TO McDERMITT RESOURCE Assay results from MDRC012 confirm substantial thickness and continuity of lithium mineralisation from surface Remaining four drillhole results expected by mid-March 2021 Jindalee Resources Limited ( Jindalee , the Company ) is pleased to announce that assay results have now been received for 11 holes of the 15-hole program completed late in 2020 at the Company’s 100% owned McDermitt Lithium Project (US). The latest results for MDRC012 confirm substantial widths of lithium mineralisation from surface in the SE portion of the deposit including : 58.0m @ 1611 ppm Li from 1.5m including 12.2m @ 2617ppm Li 27.4m @ 1477 ppm Li from 88.9m Results from MDRC012, located approximately 500m SE of the nearest hole (MDRC011), support significant intercepts recently announced by Jindalee 5 with drilling successfully confirming and extending the geology and grade continuity of the lithium mineralisation at McDermitt (Figure 1). The density of drilling is expected to be adequate to extend the current Inferred Mineral Resource 1 and Exploration Target Range 1 and convert existing Inferred Mineral Resources to Indicated status ahead of a possible Scoping Study. Figure 1 – Schematic section showing significant intercepts through the McDermitt Project. McDermitt Lithium Project – Background In late 2019 Jindalee announced an Inferred Mineral Resource of 150Mt @ 2,000ppm Li (0.43% Li 2O) at 1,750ppm Li cut-off 1 had been estimated at McDermitt (refer Table 1, below): Cut Off Mass Grade Contained LCE (ppm Li) (Mt) (ppm Li) (Mt) 1,750 150 2,000 1.6 Table 1 – Summary of the maiden Inferred Mineral Resource The Mineral Resource was estimated using a cut-off grade of 1,750ppm Li, which is considered appropriate in the context of similar projects and based on an assessment of the likelihood of future economic extraction as required by the JORC (2012) Code.

You are here! In one of the most amazing geologic wonderlands in the world! Fantastic rock exposure, spectacular geomorphic features, and a long history, including: 1. PreCambrian loss of our Australian neighbors by continental rifting, * 2. Paleozoic accretion of island volcanic chains like Japan (twice!), 3. Mesozoic compression and emplacement of a batholith, 4. Cenozoic stretching and volcanism, plus a mantle plume torching the base of the continent! Let’s start with what you can see on the playa and from the playa: the Neogene to Recent geology, which is the past ~23 million years (= Ma). Note: Recent = past 15,000 years http://www.terragalleria.com Then we’ll “build” the terrane you are standing on, beginning with a BILLION years ago, moving through the Paleozoic (old life, ~540-253 Ma), Mesozoic (age of dinosaurs, ~253-65 Ma)) and Cenozoic (age of mammals, ~65 -0 Ma). Neogene to Recent geology Black Rock Playa extends 100 miles, from Gerlach to the Jackson Mountains. The Black Rock Desert is divided into two arms by the Black Rock Range, and covers 1,000 square miles. Empire (south of Gerlach)has the U.S. Gypsum mine and drywall factory (brand name “Sheetrock”), and thereʼs an opal mine at base of Calico Mtns.

GROUND-WATER APPRAISAL OF THE BLACK ROCK OESER T AREA NORTHWESTERN NEVADA by William C. Sinclair Geologist ~··· ··. Prepared cooperatively by the Geological SUrvey, U. S. Department of Interior October, 1963 FOREWORD This reconnaissance apprais;;l of the ground~water resources of the Black Rock Desert area in northwestern Nevada is the ZOth in this series of reports. Under this program, which was initiated following legislative action • in 1960, reports on the ground-water resources of some 23 Nevada valleys have been made. The present report, entitled, "Ground-Water Appraisal of the Black Rock Desert Area, Northwe$tern Nevada", was prepared by William C. Sinclair, Geologist, U. s. Geological Survey. The Black Rock Desert area, as defined in this report, differs some~ what from the valleys discussed in previous reports. The area is very large with some 9 tributary basins adjoining the extensive playa of Black Rock Desert. The estimated combined annual recharge of all the tributary basins amounts to nearly 44,000 acre-feet, but recovery of much of this total may be difficult. Water which enters into the ground water under the central playa probably will be of poor quality for irrigation. The development of good produci1>g wells in the old lake sediments underlying the central playa appears doubtful.

  • The Historic Winnemucca to the Sea Highway “Gateway to the Pacific Northwest”
    Feb 2004 WINNEMUCCA to the SEA Highway The Historic Winnemucca to the Sea Highway “Gateway to the Pacific Northwest” John Ryczkowski The Winnemucca to the Sea highway was developed to establish a continu- ous, improved all-weather highway from US-40 (I-80) at Winnemucca, Nevada through Medford, Oregon and on to the Pacific coast at Crescent City, California. In the mid 1950’s there was no direct route west from Northern Nevada across South- ern Oregon and into California’s Redwood Empire. Community leaders from points along this proposed link formed the Winnemucca to the Sea Highway Association. The association worked with state and local governments to fund the design, con- struction and upgrade of the paved roadway for this east to west link across three states. The association had envisioned one highway number 140 applied to the complete route, as the parent major US highway was coast-to-coast US-40, the Victory Highway. Nevada and Oregon used state route 140 for their respective sections of the Winnemucca to the Sea Highway. But the renumbering or cosigning of federal highways was an obstacle that the Winnemucca to the Sea Association never did overcome, thus the hope of a continuous 140 designation for this link was never realized. Currently the traveler will follow seven different highway numbers from Winnemucca to Crescent City, they are US-95, state route-140, US-395, state Association brochure circa 1960’s route-62, Interstate-5, US-199 and US-101. Winnemucca, named after a local Paiute chief, has always been a crossroads town.
