  • Epithermal style gold-silver mineralization
  • Large hydrothermal clay alteration footprint
  • Numerous historical workings throughout the property
  • Rock grab samples up to 4.99 g/t gold and 50 g/t silver [1]
  • 2022 drilling results returned 0.56 g/t Au and 2.6 g/t Ag over 1.52 m in hole DP22-09 [1]


  • Location: 40 km east of Tonopah in Nye County, Nevada
  • Access: road accessible; ~2 km south of Highway 6
  • Tenure: 80 unpatented lode mining claims (~1,650 acres)
  • Ownership: 100% owned by Infield through ground staking

The Desperado property covers an area of approximately 1,650 acres and is located in Nye County within the historical Ellendale mining district, approximately 40 kilometres east of the town of Tonopah. Desperado is readily accessible by a series of local dirt roads connecting with Highway 6. Gold and silver at the Property are hosted within a low-sulphidation epithermal environment. The mineralization is typically structurally controlled and found at or proximal to the contact between rhyolite and andesite, with precious metals commonly associated with silicification and disseminated pyrite.

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. Historical workings and mineralization are associated with large areas of low-sulphidation hydrothermal clay alteration.


2020-2021 Exploration Program

During 2020-2021, Infield completed a surface exploration campaign at Desperado that consisted of geological mapping, prospecting, rock and soil sampling, and ground geophysical surveying, including ground magnetics ("MAG") and induced polarization ("IP"). This exploration work led to the identification of multiple gold-silver target areas across the Property prospective for gold-silver discovery. Additionally, initial reconnaissance work identified large areas of hydrothermal clay alteration within the Desperado property through a specialized interpretation of satellite spectral data.

2020-2021 Rock 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]

2022 Drilling Campaign

The 2022 Desperado drilling campaign was designed to test lithological contacts and structural features for epithermal style mineralization. Infield commenced drilling in July and completed the program in August of 2022 for a total of 1,518 metres of reverse circulation (“RC”) drilling across ten drill holes, two of which (271 metres) are located on ground no longer controlled by Infield.

Several of the selected targets exhibited chargeability highs within lithological contact zones. Drilling of these targets intersected wide zones of up to 20% disseminated pyrite within intensely clay altered rhyolite near contact zones with andesite, corresponding with the chargeability anomalies. Similarly, other targets tested on the property intersected structural features enriched in pyrite. Gold and silver in the area is known to occur in the types of rocks targeted in this campaign, however, only minor amounts of precious metals were returned from the RC rock chip samples that were submitted to the laboratory for analysis. Further review of the drilling data in context to the geological environment and additional studies would be required to better understand the potential of additional targets at Desperado.

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.

Rock grab and rock chip samples collected by Infield in 2020-2022 were prepared and analysed by American Assay Laboratories in Sparks, Nevada, for fire assays (Au-FA30-ICP) and multi-element analysis (ICP-2A036). American Assay Laboratories is an independent geochemical analytical testing laboratory which is ISO-17025 accredited by IAS.

  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).

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.
