- Metallis geologists have built a 3D model for each of the porphyry phases and gold-enriched zones at the Cliff-Miles to help demonstrate the distribution of high-grade intercepts;
- The highest porphyry grades can be tied to a semi-continuous Medium-Grained Porphyry ("MP") composed of a single dike-like feeder (or "trunk") and two sill-like branches. These grades are found in the Southern end of the Cliff target (See Schematic Figure 1 Below); and
- The best gold-enrichment grades have a North-South trending and steeply dipping tabular form that runs along the East margin of the well-mineralized MP.
The current distribution of gold and copper mineralization is divisible into porphyry-related and late-gold related allotments.
The MP porphyry phase, composed of feeders (dikes) and sill-like bodies, can be further subdivided into well-mineralized and poorly mineralized MP variants based on respective copper, molybdenum, and vein content (See Figure 2 Below).
The feeder of the well-mineralized MP variant ranges between 20 meters ("m") and 150 m thick, has only been tested as deep as 660 m below surface, and can be semi-continuously traced 2,500 m from far-south holes at Cliff all the way to the
- Far-south Cliff example intercepts include 0.8 g/t AuEq* over 118 m in KH18-16; and
- Far-north Miles example intercepts include 0.34 g/t AuEq over 84.5 m in KH19-27 (located 2500 m to the north of Cliff)
The sub-horizontal sill-like geometries are most apparent between holes KH20-34 and MD09-05 and occur in two bodies:
- A semi-continuous shallow sill tracked over approximately 950 m from North to South and which is highly variable in thickness (70 m to 250 m thick). It is still open to the South (beyond KH18-13), to the East, and potentially to the North beyond MD09-03
- Example intercepts include 0.41 g/t AuEq over 80.3 m in KH17-07 or 0.32 g/t AuEq over 170 m in KH18-11
- A deeper sill tracked over 720 m from North to South, that pinches (>40 m) and swells (<170 m) along its length and is still open to the North (beyond KH21-42), South (beyond KH20-36), and to the East.
- Example intercepts include 0.36 g/t AuEq over 129.9 m and 0.37 g/t AuEq over 198.5 m in KH20-36, or 0.37 g/t AuEq over 193 m in KH21-42
Petrographic, geochemical, and geostatistical reviews are currently underway to establish new strategies to help the geological team distinguish this new well-mineralized MP variant in-field as well as to further refine the model. A simplified view of the grade-bearing MP model and how it fits with the gold-equivalent ("AuEq") distribution can be seen in Figures 2 and 3. All the zones are still considered open to the North and South with multiple infill and extension opportunities situated near surface as well as at depth. All analytical data was completed at independent certified laboratories and have previously been reported.
Though challenging to identify texturally, the gold-enrichment event can be empirically identified from high Gold-to-Copper ratios along with silicification and can be traced along the dominant structures of Cliff-Miles (Adam Fault and block faulting) (
The 3D model shows a North-South ribbon-like feeder, approximately 2,400 m long, present on the East margin of the newly identified grade-bearing MP and which extends across the Adam Fault (380 m to 830 m deep) into the graphitic siltstone footwall. Example intercepts include:
- North-South feeder example intercepts include 1.24 g/t AuEq over 32 m in KH20-37 and 0.33 g/t AuEq over 27 m in KH18-16
Alongside, loosely constrained, are the fault-bound Northwest-Southeast feeders.
- Northwest-Southeast feeder example intercepts include 0.63 g/t AuEq over 30 m in KH21-42
Additionally, two dominant stratabound mineralized zones can be partially traced from Miles South to Cliff.
- Stratabound mineralized zones identified at Miles include 1.05 g/t AuEq over 43 m in KH21-45 and 1.24 g/t AuEq in KH20-37; and
- At Cliff with 0.82 g/t AuEq over 32.4 m in KH21-40

In addition to a better understanding of the grade-bearing MP, 3D models of the other MP variants, two phases of Course-Grained Porphyry (or "CP"), and multiple feldspar porphyry sills have been produced. The Company's planned drilling this upcoming 2022 exploration season will focus on targeting the grade-bearing MP variant and gold-enriched mineralization with systematic step outs and undercuts, with a view to constraining geology and orientations, and avoiding the now identified and historically-poorly mineralized CP phases.
Future news will pull all the latest results together to guide the geological team and help evaluate and prioritize the Company's targets for 2022 field work and drilling.
