01 / The Project
Spirit Mountain,
in context.
A look at the landscape, the work to date, and the next questions for this southern Nevada project.
01 / Overview
The project at a glance.
Spirit Mountain Gold is an early-stage exploration project in southern Nevada presented by Oro Linda, L.L.C. Historic workings, field observations, and earlier sampling provide a starting point for a new evaluation.
Location
The project is in the Spirit Mountain area, near Cal-Nev-Ari and accessible from the Las Vegas region. The mountain, known as Avi Kwa Ame to the Fort Mojave people, is part of a landscape with deep cultural significance to Tribal Nations.
Exploration approach
Oro Linda is evaluating the project in stages. Geology explains what the earlier work suggests and what needs to be tested; Current Work shows the latest status.
02 / History
Avi Kwa Ame and the Roman Mine.
Avi Kwa Ame: a living connection
Spirit Mountain, known as Avi Kwa Ame, rises in southern Nevada's Newberry Mountains. The Fort Mojave Indian Tribe traces the earthly origins of Mojave people to this mountain. The Bureau of Land Management describes continuing spiritual and cultural importance for Mojave, Chemehuevi, some Southern Paiute people, and other Tribal Nations.
Spirit Mountain was listed on the National Register of Historic Places in 1999. In 2023, the wider Avi Kwa Ame landscape was designated a national monument. These public milestones recognize a cultural connection that continues today.

The Roman Mine and the Tinnells
Recorded mining at the Roman Mine predates the Tinnell family. The selected dates below trace that work without treating historical claims as a statement of current ownership.
1937
A mining account cited by the U.S. Geological Survey describes small-scale work at the Roman Mine, historically associated with the Jackdaw group.
1980–1982
According to Tad's chronology, the family acquired the Mexican Girl claims and Roman Mine in 1980. A Nevada mining district file from 1982 lists Roman among the JETCO claims.
1999
An MK Gold letter in the project archive records a later evaluation of the family's Newberry Mountain property.
Jetco Enterprises
A Nevada mining district file identifies Roman among the Jetco claims, and a later state directory lists the Jetco Mill under Jetco Enterprises, Inc. The family preserved this logo on a T-shirt.

Private draft for review. Tribal representatives should review any expanded account of their traditions or a specific project relationship. The photograph's exact year and credit, the project's position relative to the monument boundary, and current claim status remain to be confirmed.
03 / Land & Community
A project in a living landscape.
Location and access
Spirit Mountain Gold is near Spirit Mountain in southern Nevada, southeast of Las Vegas. The project maps show the approach from U.S. 95 near Cal-Nev-Ari along Christmas Tree Pass Road.
Map images from the project presentation. Christmas Tree Pass Road reference · BLM regional land map provides wider context but does not show this project's claims.
A habitat planning record
Tad's professional records describe his work as the Searchlight liaison on Clark County's 1993–94 habitat planning committee. He recounts helping establish exclusions for Searchlight and a Tinnell area in tortoise management planning. The map preserves that history of land-use coordination.
Oro Linda will compare today's project footprint with current habitat and land-management maps before describing how any exclusion affects new work. The archived map alone does not establish the status of today's claims or environmental review.

People and place
The land around Spirit Mountain is important to nearby communities and to Tribal Nations with enduring cultural ties to Avi Kwa Ame. Oro Linda intends to explain proposed work clearly, listen to local and Tribal perspectives, and consider those perspectives as plans develop.
Specific relationships or commitments will be described after review with the people involved. Current wildlife information will guide plans for any new field disturbance.
Private draft for Tad's review: confirm the mapped exclusion's official record, the present claim footprint, current land status, access, and any site-specific wildlife requirements before publishing operational or cost claims.
04 / Geology
Reading the rock.
What we can see
At Spirit Mountain, I start with the rock in front of me: quartz veins, fractures, and changes in the surrounding rock. In this short field video, I show a sample with small open spaces called vugs. It is one clue to how the quartz formed and a reason to look closer. The assays tell us what was in the samples we tested.
What earlier work found
A 1983 report on an earlier Searchlight property recorded gold and silver in selected quartz vein material. A larger sample from the same spot, with more surrounding rock in it, tested lower. The values were not spread evenly across everything sampled.
A 1986 geological review of a broader historic Spirit Mountain property described veins, smaller veinlets, and altered rock with local gold, silver, and copper occurrences. It called for more detailed sampling and mapping. In 1999, MK Gold collected rock chips in the Newberry Mountain area and saw encouraging results for narrower targets, although those targets did not fit its large bulk-mine program. To me, the thread through these reports is clear: the structures deserve careful follow-up, while the extent and consistency of mineralization remain to be established.
What comes next
I want to match the old sample locations to the ground we are evaluating today, map the veins and altered rock in more detail, and collect new, well-documented samples for independent analysis. We are also exploring a subsurface survey method that could help focus where we investigate. That work can test whether the promising points in the old record connect into something more continuous.
Approved investors will be able to check the original reports, sample descriptions, and assays in the data room.
Sources behind this draft: Carole Olsen’s 1983 Searchlight property sampling report; M. Dean Webb’s 1986 Spirit Mountain preliminary geological report; MK Gold’s 1999 Newberry area review. Their sample areas reflect earlier property work and will be reconciled with the current project map.
05 / Project status
Current Work
Oro Linda is organizing historical reports, assays, maps, and claim records into a traceable project archive for review.
Discussions about a possible subsurface survey are continuing. The method, partner, and field scope have not been finalized. This section will carry dated updates as work is scheduled and results can be shared.
