Sierra Plata

Location: Zacualplan / Taxco, Mexico
Size: 2,200 ha.
Stage: Pre-Drill / Advanced Targeting
Deposit Type(s): Epithermal Silver–Antimony
J2 Interest: 100%

Overview

Located in the historic Zacualpan–Taxco District, one of Mexico’s most established silver-producing regions with more than 500 years of mining history. It was one of the most important silver and gold districts in the Spanish Empire.

Project area hosts multiple past-producing silver-gold mines, providing clear evidence of a robust, repeatable mineralizing system and reducing geological risk.

Strong silver and antimony prospectivity associated with structurally controlled epithermal vein systems, with antimony (stibnite) acting as both a valuable co-product and indicator of a fertile hydrothermal system.

Numerous productive trends and fault structures identified. Near-term plan includes magnetic survey, LiDAR, and geochemistry, followed by drill testing to expand known mineralization and test unexploited extensions.

The Zacualpan District, located near the historic mining center of Tacxo in Guerrero, is one of Mexico’s well-established precious metals districts with a long legacy of silver production. The district benefits from excellent infrastructure, skilled local workforce, and a strong mining culture that has supported continuous exploration and development for more than a century.

Location and Access

Sierra Plata is located next to projects owned by Grupo Mexico and Pantera Silver. The project area is well accessed by dirt roads and is can be easily reached by vehicle from Taxco. A major regional Mineralizing structure runs NW-SE and connects Zalcualpan with Taxco.

Geology and Mineralization

Sierra Plata is located between Taxco and Impact’s producing Zalcualpan Property within the Taxco epithermal belt.

It is located at a higher elevation than the mineralized systems at Taxco and Zalcualpan and in geological units that regionally overlie the Acapetlahuaya Formation where the bulk of the silver production has occurred from. We believe the vein system continues at depth at Sierra Plata.

Sierra Plata’s surface geology consists of intercalated stratas of shale and limestone with lesser Intrusive Rhyolite proximal to major fault structures.

Satellite hyperspectral data has identified zones of argillic alteration which signify the tops of potential epithermal systems at Sierra Plata.

Epithermal veins crosscut all strata while the manto-style Limey Sandstone found at the lowest elevation (1900m) dips 25 degrees to the NNE.

Future Plans

J2 Plans to undertake a close spaced drone magnetic survey at the soonest opportunity in order to help refine our structural understanding of the property and to help identify possible 2nd order structures that may host bonanza mineralization.

This information in conjunction with added geochemistry and alteration mapping will improve drill targets for phase two drilling.

Napoleon

Location: Alaska, USA
Size: 5,925 ha.

Deposit Type(s): Orogenic Au /
Intrusion related Au
J2 Interest: 100%

 Technical Presentation

Overview

The Napoleon Project lies in the heart of the Tintina Gold Province, a region spanning 2000 kilometres that has produced more than 30 million ounces of gold.

Napoleon is located in the Fortymile Region of Eastern Alaska, which has produced an estimated 500,000 oz of placer gold. Despite this extensive placer production, no major hard rock or “lode gold” production has been documented in the district.

J2’s exploration focus, led by Technical Partner Kenorland Minerals, is testing the Napoleon Creek Intrusive, the most significant intrusive gold system in the region as a possible source for the coarse grain placer gold that is found in all drainages surrounding the property.

The Tintina Gold Belt has yielded an estimated 30 million ounces of gold. Numerous projects and production mines throughout the belt have Au gross metal contents from current resource estimates that total more than 80 million ounces of gold (Source).

Location and Access

The Napoleon project covers 5925 hectares of state-owned Alaska mining claims. It is located 15km northeast of the town of Chicken or 140 km from the town of Tok along the seasonal Taylor Highway. The property is accessed via a network of four-wheel-drive trails which follow the ridge tops throughout much of the project area.

Geology and Mineralization

The property is located within Alaska’s historic Forty Mile Mining District, which is part of the prolific Tintina Gold Province. The Tintina hosts significant deposits such as Donlin Creek, Fort Knox, Pogo, Livengood, Coffee Brewery Creek and Dublin Gulch. Gold mineralization at Napoleon is related to a regional shear zone which intersects the Jurassic aged Napoleon pluton. Gold mineralization is controlled by east-west and northwest trending structures and are commonly kaolinite-quartz-carbonate altered. High-grade gold is associated with quartz-pyrite veins, with K-feldspar-sericite-pyrite altered selvedges.

Exploration History

Kennecott first staked the property in 1998 following regional compilation work that identified anomalous gold-in-stream-sediment samples reported by Phillips Petroleum in 1982. Kennecott carried out soil sampling over areas of known mineralization as well as stream sampling throughout the property. During the 1998 and 1999 field seasons, soil geochemistry and trenching led to the discovery of five target areas: Main Zone, Saddle Zone, Trench 24, Twin Peaks and Burnt Ridge. Kennecott subsequently drilled 6 diamond drill holes and 10 RC holes with highlights including 0.61m @ 38.26 g/t Au in hole NAP-3 and 9.2m of 1.8g/t Au in hole NRC4.

Teck Resources explored the Napoleon property between 2000 and 2001. Exploration included ground magnetic and induced polarization geophysical surveys, and additional soil sampling. This work was subsequently followed up with 11 diamond drill holes, returning 74m of 0.9g/t including 0.90m of 22.7 g/t Au in NP-10 and 3.0m @ 8.9 g/t Au at the Saddle Zone in hole NP2.

A total of 4759 meters over 27 holes were drilled by Kennecott and Teck resources. Average hole depth was 166m
Between 2007 and 2009 Millrock Resources Inc. conducted additional soil and rock sampling along with a review and evaluation of existing data to generate additional drill targets. Millrock did not conduct any drilling on the property and the ground was eventually relinquished.

Northway Resources Corp. (Northway) acquired the Napoleon property in 2019. Exploration activities conducted by Northway in 2020 included a ground-based magnetometer and very low frequency electromagnetic (VLF-EM) survey and infill C-horizon soil sampling over the main target areas to help define drill ready targets.

Future Plans

In 2022 J2 completed a 2417km drone magnetic survey with LiDAR. The 50m spaced survey produced a high quality and resolution dataset that will help guide drilling on targets away from the main zone at a future date.

Miniac

Location: Quebec, Canada
Size:
Stage: Early
Deposit Type(s): Polymetallic Volcanogenic Massive Sulfide (VMS), Intrusion related Au
J2 Interest: 100%

Overview

The Miniac Project is a VMS target located in the Northern Abitibi Volcanic zone, part of the Abitibi Greenstone Belt, one of the largest gold endowed districts in the world. Located between the past producing Normetal mine and the Osborne-Bell mine along the Chicobi fault system, Miniac is an exhalative polymetallic system consisting of Au, Ag, Cu and Zn massive sulphides along a felsic-mafic volcanic contact.

Location within the Abitibi Region with known Metal Endowment (Source).

Location and Access

The Miniac Project is located approximately 30km North of the town of Amos, Quebec. It is easily accessed by an extensive network of gravel logging roads across the entire claim package. A power line is 7 km away.

Geology and Mineralization

Miniac is located in the North Volcanic Zone of the Abitibi Greenstone Belt. Geology on the property consists of a mix of mafic to intermediate volcanic and ash tuffs as well as granitic units. Outcrop exposure is poor and the property is covered in glaciolacustrine clays.

Widespread anomalous Au-Ag-Zn-Cu mineralization has been intersected across a 4km strike length at Miniac. Mineralization is interpreted as sulphide facies exhalative horizons composed of pyrrhotite-pyrite +/- chalcopyrite and sphalerite. There is possible Au enrichment from an interpreted NNW trending splay structure off the Chicobi deformation zone. The massive sulphide horizon lines up well with conductivity geophysics.

Historical Drilling

Historic drilling has targeted EM anomalies over a 2km by 4km strike length.

Highlighted historic drill intercepts include 4.80 g/t Au over 0.60 m and 4.80 g/t Au, 6.88 % Zn and 1.05% Pb over 0.30 m (DDH DV-80) and 1.37 g/t Au over 4.00 m, 2.06 g/t Au over 5.50m and 1.71 g/t Au over 2.40 m (DDH DV-119). Drilling to test VTEM anomalies in 2020 yielded 1.05g/t Au and 0.16% Zn over 4.65m in drillhole 20MDD004.
Drilling at Miniac has intersected alteration and geologic features comparable to distal features at the LaRonde Au VMS deposit. This suggests good exploration potential at depth.

Future Plans

The Miniac Project is currently optioned to Stearman Resources who completed a high resolution drone magnetic survey and inversion modelling in 2023 and 2024. The interpretation identified 19 high priority targets for follow up drilling.
