Fiore Gold Ltd. 100 % Direct
Fiore Gold Ltd. was formed on September 25, 2017 pursuant to an Arrangement Agreement (the “Arrangement”) dated July 24, 2017, whereby GRP Minerals Corp. (“GRP”) acquired Fiore Exploration Ltd. (“Fiore Exploration”), combining their businesses to create Fiore Gold Ltd., a new Nevada based gold production and development company.

The Pan Mine is owned by GRP Pan, LLC.

Deposit Type

  • Breccia pipe / Stockwork
  • Carlin-type


Summary:

Alteration associated with the Pan deposits is typical of Carlin-style gold systems, and includes silicification, argillization, decalcification, and oxidation. Breccia bodies may be silicified (jasperoid) or argillized and can contain variably altered fragments, including silicified, clay altered, and/or decalcified fragments. The Pilot Shale-Devil’s Gate Limestone contact may be argillized and/or decalcified.

Mineralization at Pan occurs in strongly oxidized rock. Oxidation is prevalent throughout each of the zones with strong development of iron oxides (hematite and limonite). Liesegang banding is formed in the Pilot Shale in association with oxidation. Sulfide minerals have rarely been described in drill logs at Pan, and are not associated with the gold mineralization.

The bulk of the mineralized area contains elevated barite levels, typically above 0.2%. Hydrothermal barite veins are present in the southeast portion of the property in association with the old Cue Ball Barite Mine, briefly worked in the 1970s.

Gold deposits at the Pan Project generally occur as elongate pods in association with structures and solution or hydrothermal breccia bodies hosted by the Pilot Shale and, to a lesser extent, the Devil’s Gate Limestone. Gold deposits also occur as more tabular bodies hosted by altered and mineralized sedimentary horizons. Mineralization occurs along a north-south trend approximately 5,000 feet long and 500 to 1,000 feet wide. Cross sections typical of the North and South Pan zones are shown on Figure 7-4 and Figure 7 5.

North Pan mineralization is predominantly hosted in breccias developed in the moderately folded Pilot Shale along the Branham fault and other structures to the west. Gold mineralization has been identified to depths up to 650 feet, but remains open at depth and to the north under volcanic cover.

The Central Pan zone contains mostly sub-horizontal, tabular mineralization hosted along the Pilot Shale- Devil’s Gate Limestone contact. Mineralization in the Black Stallion and Syncline areas is dominantly hosted in folded and faulted Pilot Shale, but also occurs in Devil’s Gate Limestone. This area of mineralization has potential for expansion with additional drilling.

In South Pan, there are two important ore zones; the South Pan Main zone and the Wendy zone (Figure 7-5). The South Pan Main zone is associated with solution/collapse breccia along or adjacent to the Branham fault zone. It is 100 feet to perhaps 300 feet wide in plan view. The zone is strongly argillized breccias of host rock shale or limestone which have lost most or all of their primary texture. Sporadic or irregular silicification is also present. Mineralization is irregularly distributed in patterns suggestive of en echelon pods.

The Wendy zone is stratiform and straddles the contact between the Pilot Shale and the Devil’s Gate Limestone in the domain to the east of the Branham fault zone. This zone can be up to 300 feet wide perpendicular to bedding and extends down-dip from the surface to as deep as drilling has penetrated the zone at about 700 feet deep. Mineralization generally extends further into the Pilot shale than the Devil’s Gate Limestone, and may be slightly better grade in the Pilot shale as well. The zone is not tabular, but pinches and swells along strike and down-dip. The mineralization is largely associated with moderate to strong argillic alteration but pods of strong silicification are present associated with layer parallel solution/collapse breccias or possibly sandy, more permeable beds. At present, large amounts of altered limestone ore have been mined and occur in the South Pan highwall. Once the trace of the Pilot Shale-Devil’s Gate Limestone contact intercepts the Branham fault, the contact plunges down to the north below the surface. Drilling along this plunging contact has intercepted mineralization well to the north of the current South Pan pit.


Mining Methods

  • Truck & Shovel / Loader


Summary:

Currently, conventional open pit mining methods are implemented at Pan. A contract miner is conducting the mining activities. Ore and waste is drilled and blasted, then loaded into 100-t payload haul trucks with 14-15 LCY bucket capacity wheel loaders. The loading and haulage fleet is supported by track dozers, motor graders, and water trucks. Waste is hauled to waste rock storage facilities near each pit. Ore is currently hauled and placed directly on the heap leach pad.

All mine production equipment is provided by the mining contractor. Equipment on site includes CAT 992G/K loaders and CAT 777 off highway haul trucks. The contractor utilizes two Atlas Copco DM45 drills for blasthole drilling. Presently, there are six haul trucks at the mine, two more will be needed in 2017, and another two will be needed in 2018.

Summary:

The Pan Project uses a heap leach process to extract gold and silver from ore. The heap leach process extracts gold and silver by placing ore on an impermeable pad and applying a diluted cyanide solution that dissolves a portion of the contained gold and silver, which are then recovered in metallurgical processes.

Current mining operations use a blending process of North pit rock ore and South pit clay ores to alleviate previous permeability issues arising from the placement of high clay content ore on the heap leach pad. An approximate 60% rock ore to 40% clay ore ratio, using ore from both North pit and South pit, is being blended on the heap leach pad to ensure adequate permeability.

The existing leach pad is designed to be a multi-lift pad that will accommodate ore stacked to an ultimate height of 160 ft. Individual lifts are designed to be 15 to 25 ft. The initial pad was designed to hold 9.2 Mt of stacked ore.
