The Desperado property is located in Nye County within the Ellendale mining district, approximately 40 kilometres east of the town of Tonopah and 2 kilometres south of Highway 6. Desperado is readily accessed by a series of local dirt roads. It covers an area of 1,410 hectares (3,480 acres) surrounding the historical Ellendale mine property owned by a third party and lies at an altitude of 1,830 metres (6,000 feet) in the foothills at the southern end of the Monitor Range overlooking the Ralston Valley to the southwest.

The Ellendale mining district was discovered in 1909 by Ellen Clifford Nay when she found high-grade gold in a large rock float. Most of the work in the area was conducted between 1909 and 1915 and is noted by several abandoned adits, shafts and trenches. The district remains underexplored with no indication of modern exploration work having been conducted within the property area during at least the past 30 years.[5]


Most of the historical workings are found in rhyolite near the contact with andesite porphyry. The rhyolite is fine grained and rather siliceous and carries small phenocrysts of quartz and feldspar. Based on field observations, epithermal-style gold and silver mineralization appears to be associated with silicified-sericitized rhyolite breccia and quartz veins proximal to the rhyolite–andesite contact. The USGS Mineral Resource Data System reports four mineralized prospects on the property that correspond to historical workings, though several additional workings have been identified that were not reported by the USGS. The historical workings and mineralization are associated with large areas of clay alteration.

2020 Evaluation Program

During the fall of 2020, Infield carried out field reconnaissance and sampling at the Desperado property. Rock grab samples from the program returned grades as high as 4.99 g/t gold and 50 g/t silver.[1]

2020 Sample Highlights:

  • 4.99 g/t gold + 50 g/t silver (mine dump sample)[1]
  • 2.15 g/t gold + 6 g/t silver (quartz vein in prospect pit)[1]

The Company identified large areas of hydrothermal clay alteration within the Desperado property through a specialized interpretation of satellite spectral data. During a field inspection, 60 clay altered rock samples were collected from the alteration areas and subsequently analysed using a Terraspec Spectrometer to evaluate the nature of alteration. The minerals identified in the study were consistent with low-sulfidation and high-sulfidation clay alteration in epithermal systems.

2021 Exploration Program

In April 2021, Infield carried out a systematic soil sampling program across an extensive zone of hydrothermal clay alteration. The survey included 710 samples on a grid mesh of 100 x 100 meters, covering an area of approximately 4 kilometres by 3 kilometers. The soil survey results indicate that anomalous silver in soil is distributed over an area of 3.5 kilometres in length by 500 to 800 metres in width. Anomalous values for gold in soil over the same area are erratic, which can be expected due to the poor mobility of the element. Two additional elements of interest, arsenic and manganese, that are generally associated with silver mineralization in the Tonopah region, were also found in relation to the anomalous silver area. A silver-gold target area has been outline at the Desperado property utilizing the 2021 soil program results.

Infield plans to follow up with additional fieldwork at Desperado during Q3-Q4 2021 with the intent to advance the property toward a drill ready status. The program will include field evaluation of the silver-gold target area to determine the prospects of mechanical trenching, as well as to propose the layout of a grid for ground geophysical surveying.

The potential quantity and grade of mineralization described herein is conceptual in nature as there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in targets being delineated as a mineral resource.


  1. Rock samples collected by Infield in 2020 were prepared and analysed by American Assay Laboratories in Sparks, Nevada. Gold was analysed using Au-FA30/ICP and multi-element analysis was conducted using ICP-2A036 (50 elements). American Assay Laboratories is an independent geochemical analytical testing laboratory which has been ISO-17025 accredited by IAS.

  5. The information on the Ellendale Mining District and its geology was obtained from the Nevada Bureau of Mines and Geology District files, the USGS and other published documents.
  6. Soil samples were delivered to the ALS geochemistry laboratory in Elko, Nevada, for preparation. The samples were then analyzed at ALS laboratories in North Vancouver, British Columbia, for 53 elements (ALS code ME-MS41L). ALS preparation and analytical laboratories are independent and have ISO/IEC 17065 and 17025 accreditations from both ANSI and SCC.

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
