Silver One Resources identifies 13 exploration targets at Candelaria
The Nevada silver explorer staked 382 claims after a May survey outlined silver anomalies and possible copper-silver-gold porphyries.

An airborne survey has outlined 13 exploration targets and prompted a land expansion around a historic Nevada silver mine. Silver One Resources Inc. CVESVE OTCMKTSSLVRF FRABRK1, a Vancouver explorer that owns the Candelaria project, reported seven silver targets and six potential copper-silver-gold porphyry targets on Tuesday.
The last TSX Venture quote for CVESVE was C$0.49 at 4:00 p.m. EDT on Oct. 9. The U.S. OTC quote for OTCMKTSSLVRF was US$0.34 at 4:00 p.m. EDT on Oct. 12. Both readings predate the Oct. 13 announcement.
Silver One said the May 2026 helicopter survey and subsequent reconnaissance led it to stake 382 claims covering 3,128 hectares southwest of its existing property. The six possible porphyries are interpretations of electrical patterns, while the silver targets also draw on structural analysis. The announcement recommends further exploration of both groups.
The work feeds into an up to 25,000-metre drilling campaign announced on May 27. Silver One's Oct. 13 account says drilling is already testing CM-01, the northeast extension of mineralization associated with the historic Mount Diablo and Northern Belle mines. The wider target inventory still requires field investigation.
Six Potential Porphyries Remain Geophysical Interpretations
Survey contractor Geotech Ltd. conducted the airborne work, processed the data and produced three-dimensional models and targeting analysis. Its porphyry interpretation identifies resistive zones surrounded by extensive conductive envelopes. Silver One says the centres could represent intrusive stocks, with surrounding conductivity potentially reflecting altered rock or sedimentary formations.
The interpreted systems range in size from several hundred metres to between one and two kilometres. Those dimensions describe possible geological features identified through the survey. The announcement does not assign those six targets a mineral resource, copper tonnage or development budget.
A general caution comes from Richard J. Blakely and Darcy K. McPhee, authors of the deposit-scale geophysics section in the U.S. Geological Survey's 2010 porphyry copper model. Their discussion identifies clay minerals, graphite and metallic sulphides among materials affecting electrical resistivity. Conductivity therefore has several possible geological explanations; the model is a general exploration reference, not a review of Candelaria.
Geotech identified the seven silver targets using an algorithm that combines structural information with resistivity data. The inputs include known and inferred faults, geological contacts and magnetic ridges. Silver One says the resulting silver targets trend roughly east to west and have resistivities below 120 ohm-metres.
Most of those anomalies lie in or beside densely fractured zones, with CM-03 and CM-07 identified as exceptions. The company says none of the seven areas has been mapped or sampled in detail. CM-01's ongoing drilling and the reconnaissance of the other targets are separate stages of that investigation.
Reconnaissance Includes Previously Reported Samples
The Oct. 13 release describes 92 selected and channel rock samples, with maxima of 4.89 per cent copper and 272 grams per tonne silver. The observations include historic mine workings and hydrothermal alteration. These are rock-sampling results from the reconnaissance, rather than reported drilling intervals through the potential porphyries.
The sampling table refers to June 2026 work but also flags samples previously reported on June 13, 2022. Its highest values therefore cannot all be treated as newly reported assays. The table's distinction separates the new survey interpretation from mineralization documented before the helicopter campaign.
Reconnaissance at CP-03 and CP-04 returned copper values ranging from 314 to 20,898 parts per million, according to the release. Silver One says more than half the property is covered by younger volcanic rocks or loose surface deposits. It identifies ground geophysics, soil geochemistry and stratigraphic analysis among the methods needed for follow-up exploration.
"By staking 382 new claims, we have secured the ground necessary to advance these targets," Silver One president and chief executive Greg Crowe said in the Oct. 13 release.
The same release cites 120.7 million silver ounces in measured and indicated resources at Candelaria. It lists another 12.6 million silver ounces in inferred resources. Those disclosed resource figures are distinct from the seven silver anomalies and six potential porphyry targets outlined by the survey.
The exploration update lands alongside the sector's third-quarter production reports. First Majestic Silver Corp. TSEAG NYSEAG FRAFMV, which operates four underground mines in Mexico, reported 3.4 million attributable silver ounces for the third quarter of 2026. That was down 9 per cent from the second quarter.
First Majestic attributed the lower silver production mostly to a labour dispute that disrupted San Dimas for 12 days during the quarter. Its operating figures measure delivered mine output, while Silver One's survey supplies targets for exploration spending.

The next test is drilling along the CM-01 extension within Silver One's 2026 campaign. The May 27 plan also included resource expansion, exploration outside the existing resource footprint and preliminary condemnation drilling for infrastructure planning. The Oct. 13 update establishes that CM-01 drilling is underway; the dates of the next assays and tests of the potential porphyries remain unverified.
