The Cross Hills Project is an Iron Oxide Copper Gold (IOCG) project composed of 493 claims covering 12325 hectares which was acquired through a combination of staking and an option to purchase acquisition. The project lies on the southern portion of the island of Newfoundland and Labrador. The project is accessible by local paved roads and a network of ATV trails.
The project over its history has been explored for various metals including, copper, gold, uranium and rare earth metals, mostly in singular fashion. Several companies over the last 15 years have examined the project for IOCG potential with positive results, however, no company has completed a focused exploration program to unlock its potential. Zonte has been exploring the project for the last two years.
Exploration has identified a series of targets defined by some combination of magnetic, gravity, IP and mineralization data that lie along the Cross Hills Fault and spatially related cross and splay faults. The most northern target is called the Dunns Mountain target, which shows an association of copper, gold and silver mineralization associated with a large coincident magnetic and gravity anomalies. Phase 1 drilling discovered high-grade mineralization (see below) and the first few holes in Phase 2 identified long sections of core with spaced microfractures with mineralization. Notable drill results are below with drill hole CH-19-004 showing:
The drill hole map, illustrated below, shows the drill holes projected to surface.
Drill results from CH-19-004 are noted in the table below.
Note, the true width of the zone has not been determined. Bo = bornite, cc = chalcocite, cpy = chalcopyrite, mal = malacite, az = azurite and mag = magnetite.
Additional pictures of select mineralized intervals can been observed on the Company’s Instagram account.
Drilling in Phase 1 has highlighted that the mineralization sits most likely on the periphery of the magnetic anomaly, and in the immediate case with Dunns Mountain on the eastern side. The recently completed gravity shows a large gravity sitting under the magnetic profile. The image below shows the core of the gravity anomaly sitting below the magnetic profile, while the gravity anomaly itself is large extending beyond the magnetic anomaly. Phase 2 drilling will test areas throughout this gravity anomaly.
The image below exhibits the large gravity anomaly discovered under Dunns Mountain. The target is large, measuring 750m long, 400m wide and up to 1000m deep.
The Company completed a large airborne magnetic survey during the fall of 2020. The survey identified numerous anomalies throughout the project and ground truthing each anomaly is ongoing. One recently checked anomaly was a large 3km by 2.5 km magnetic anomaly about 2km north of Dunns Mountain. The anomaly is named "North Dunns". The anomaly was visited only on the very northern side in a limited manner to date. Several copper showings were discovered, however, most of the anomaly is covered and now will be explored using geochem and geophysics. The anomaly, illustrated below, is multiple times larger than Dunns Mountain which is also illustrated in the image. The Company expects to find additional targets throughout the airborne surveyed areas.
The airborne magnetic survey has identified the largest magnetic anomaly at about the centre of the property. The anomaly called Nine Mile measures 4km X 2.5km. Prospecting has discovered disseminated chalcopyrite mineralization on a number of areas of the property, which is denoted on the following image. A MMI soil sampling survey has also identified areas of anomalous copper. The soil program was widely spaced to cover the large anomaly and follow-up sampling to tighten the anomalies is required.
Previous ground magnetic surveys identified large anomalies at the Carols Hat area, which sits just south of Dunns Mountain. These anomalies are large with the Big K target measuring 600 by 700m and up to 700m deep. The 2019 gravity survey identified a large gravity anomaly associated with the Big K target, which is on the order similar in size to that at Dunns Mountain. Images of the magnetic and gravity anomalies are below.
A Third area of focus for the Company lies 12km south of Dunns Mountain, where a mag survey has discovered the K6 target in 2018. At surface copper mineralization has been identified in a number of showings and indications. Copper mineralization is characterized as chalcopyrite, malachite and azurite all associated with iron oxide alteration, magnetic and gravity anomalies. Two drill holes were completed at K6 with anomalous values intersected. This target will be further drill tested. .
A plan map of the target, including the magnetics and gravity are illustrated below.

The K7 target, which sits about 1.7km south 0f the K6 target is defined by a large gravity anomaly, sitting on the edge of a magnetic anomaly. The first two drill holes were completed on the eastern edge of the gravity anomaly from the same drill pad. Both holes intersected anomalous copper, silver and rare earth mineralization. One hole tested the top of the gravity anomaly on the eastern side, and the second tested the flank of the gravity anomaly, aiming towards the magnetic anomaly. The target is large, sits about 130m below surface and extends vertically deeper which is observed in the image below.
Subsequent to the drilling the company completed a large MMI soil sampling program which identified large areas of anomalous copper adjacent to the gravity anomaly. Future drilling at the target will focus on flanking copper anomalies and the deeper centre portion of the gravity anomaly.
The Cross Hill areas has also been recognized by the Geological Survey of Canadawho noted it in a technical paper (Iron Oxide Copper-Gold (±Ag ±Nb ±P ±REE ±U) Deposits: A CANADIAN PERSPECTIVE, by Lousie Corriveau in 2007.

Zonte is focusing on three Canadian projects; one copper and two gold projects. Drilling on the copper and one gold project has identified two discoveries.
