Is Railroad Valley The Next Clayton Valley?

The Railroad Valley basin (RRV) is a green-fields lithium target believed to be similar to Clayton Valley, just 200 km to the west-southwest. AMERIWEST RECENTLY ACQUIRED additional increasing the size of THE RRV PROPERTY to 780 contiguous claims totalling 15,300 acreS.

  • Presence of evaporates
  • Surrounded by volcanic rocks (a known source for lithium)
  • Surface samples exhibiting positive lithium in sediments
  • Massive gravity lows
  • Likelihood of a deep basin containing a thick sequence of saturated sediments
  • Enclosed, fault-bounded basin valley
  • Dry lakebed (playa)
  • Exposed to evapotranspiration
  • Near surface waters cropping out

Railroad Valley may ACTUALLY be better…

Railroad Valley’s massive gravity low, is a geological feature that provides clues to the presence of underground lithium-bearing brines or aquifers

  • Comparable in size to the Salinas Grandes salt flat in Argentina; potentially one of the best lithium resources in the world. When compared to the nearby producing Clayton Valley, the whole of Railroad Valley is twice the size.

  • While Railroad Valley is geologically similar to nearby Clayton Valley in many significant ways, it differs in that it represents a new and virtually unexplored target, with only a handful of companies present, unlike Clayton Valley’s leases, which are fragmented across many competing companies.

  • Water rights are also a positive factor, with no competition for water rights existing within Railroad Valley. In sharp contrast, water rights in Clayton Valley are held by only 2 companies, with 1 of them – the multi-billion-dollar Albemarle – contesting any further applications.

  • Historic oil drilling activities and seismic surveys have amassed invaluable data for targeting potential brine aquifers.

Railroad Lithium Project

  • Ameriwest’s Railroad project encompasses 9,097 acres for total of 462 placer claims and is located within the vicinity of Township 5 North, Range 55 East.
  • Within the project area there appears to be a convergence of several factors favorable for lithium brine formation, including a deep hydrological reservoir covered by an evaporative playa.
  • Railroad Valley offers significant historical exploration data due to substantial efforts for oil and gas exploration

Railroad Valley’s basin characteristics, proximity to infrastructure, and Nevada’s stable and mining-friendly government, offer a compelling reason to ramp up lithium exploration activities in the valley.

  • Roughly 48 miles (~77 km) to the northeast of Railroad Valley is Ely, Nevada, where accommodations, skilled workers and heavy equipment are available.
  • Around 125 miles (200 km) north is Elko, where drilling/mining contractors and services are available.

Railroad Valley has a number of unique geologic attributes that could potentially enhance the occurrence of lithium mineralization.

The valley is structurally controlled by an active tectonic setting. This resulted in volcanic activity on the northwest and west margins of the valley, including the stunning Luna Craters.

  • Active faulting has created conduits that allowed geothermal fluids to rise to the surface to form numerous hot springs.
  • We anticipate these hot springs contain elevated levels of lithium and over the millennia enriched the lacustrine sediments of Railroad Valley. Our field work will include sampling of the geothermal manifestations and analyze them for lithium, plus other elements.
