Lara VMS
Offering a unique investment opportunity in a project with demonstrated potential for significant mineral wealth.
Overview
The Lara Project is a high-grade volcanogenic gold and base metal deposit and is considered to hold excellent potential for the establishment of sufficient reserves to justify a mining operation.
The Property is underlain by the McLaughlin Ridge Formation (Horne Lake-Cowichan uplift) which is correlative with the Myra Formation (Buttle Lake uplift) sequence of felsic volcanic rocks that hosts the Zinc (Zn)-Lead (Pb)-Copper (Cu)-Silver (Ag)-Gold (Au) Volcanogenic Massive Sulphide (“VMS”) deposit of Myra Falls (~147 km to the north). The past producing Cu-Pb-Zn-AU-Ag mine and mineralized zones at Mt. Sicker, ~2 km southeast of the Property, are also hosted by the felsic volcanic rocks of the McLaughlin Ridge Formation (Belik, 1981; MINFILE, 1990a).
The Lara Project was the subject of previous exploration activity in the 1980’s consisting of 323 historical drill holes totalling more than 58,263 meters, as well as 679 meters of pre-production underground access and drifting. The most recent exploration work on the Property was a carried out in 1998 by Nucanolan Resources Ltd. who completed a diamond drilling program of 12 drill holes (2,559 meters) with their best reported intersection of 3.16 m@ 2.48% Cu, 1.19% Pb, 12.3% Zn, 49.80 g/t Ag, 2.30 g/t Au.
A high grade, historic resource (not NI 43-101 compliant) was reported in 1998 by Nucanolan Resources Ltd. to be 580,000 tonnes grading 5.87% Zn, 1.22% Pb, 1.01% Cu, 0.138 opt Au (4.3 g/t Au) and 2.92 opt Ag (90 g/t Ag) over and average thickness of 8.3 feet or 2.53 meters (Archibald, 1999).
A Mineral Resource Estimate was completed on the mineralized zones within the Coronation Trend in 2008. Wireframe models were generated for mineralization envelopes in which a continuous zone of >1.0%Zinc-Equivalent could be consistently followed and modeled. In most instances, the significant intersections were reconciled from section to section without the inclusion of low-grade intervals. The Coronation Trend was modeled as six discrete zones with a total strike length of approximately 1,180 meters along a 118° trend. The average dip of the zones is approximately 65° to the north-northeast. The true width of the zone models ranges from 2 to 15 meters and averages approximately 5 meters.
The presence of additional polymetallic zones in a predominantly felsic volcanic package and the presence of numerous untested geochemical and geophysical anomalies are encouraging for continued exploration on the property. These features are complimented by existing infrastructure including nearby power and population centers.

Location
The Lara Property, located in the southern part of Vancouver Island, lies approximately 75 km north of Victoria, 15 km northwest of Duncan and 12 km west of the Village of Chemainus, British Columbia, Canada (Figures 4-1 and 4-2). The Property, situated in the Victoria Mining Division, is centered at 48°52'52" N and 123°54'18" W (NAD83 Zone 10 North: 5414789mN and 433651mE) and is covered by the 1:50 000 National Topographic Series (“NTS”) map sheet 92B/13 [Duncan] and 92C/16 [Cowichan Lake].
What is a VMS Deposit?
Franklin et. al. (2005) defined volcanogenic massive sulphide deposits as stratabound accumulations of sulphide minerals that precipitated at or near the sea floor. All VMS deposits occur in terrains dominated by volcanic rocks, although individual deposits may be hosted by volcanic or sedimentary rocks that form part of the overall volcanic complex (Franklin, 1996). VMS deposits primarily occur in subaqueous, rift related environments (i.e. oceanic, fore-arc, back-arc, continental margins, or continental) and hosted by bi-modal mafic-felsic successions, where the felsic volcanic rocks have specific geochemical characteristics. The Property has previously been classified as a VMS deposit because of the apparent stratabound nature of the mineralized zone. However, the Property also has affinities to epithermal deposits which is common in VMS deposits and the reported conformable nature of the mineralized zone could be due to the development of preferred mineralization along zones of structural weakness. The most common deposit types in the area are porphyry deposits, polymetallic base metal veins and the subvolcanic Cu-Ag-Au (As-Sb) deposit type.
Geology and Mineralization
The geology of Nova Pacific Metals’ “LARA Property” is a continuation of the Mount Sicker mine immediately to the east. It also holds similarities to the Buttle Lake mining district where some 31 million tons of polymetallic massive sulphide ore was mined. The property lies within a broad anticline structure in Paleozoic volcanic and sedimentary formations, with two mineralized zones called the Coronation zone & the Coronation Extension zone, together referred to as the Coronation Trend. The rocks have been strongly deformed, with an early event producing strong schistosity and cleavage. The property is underlain by the Sicker Group volcanics within the Cowichan uplift. The Lara property itself is underlain by the McLaughlin Ridge FM which has been thrust over the younger Cameron River Fm and the Nanaimo Sedimentary Fm along the major Fault called the “Fulford fault”. The McLaughlin Ridge Fm has been locally intruded by gabbro and diorite sills. On the property the Sicker Group and Karmutsen intrusive units are unconformably overlain by the clastic sediments of the late cretaceous Nanaimo Fm. The McLaughlin Ridge Fm, the host of the VMS deposits consist of northerly dipping, west-northwest striking rhyolitic to andesitic rocks.
Additional Highlights
- Indicated resource of 1,146,700 tonnes at 3.01% Zn, 32.97 g/t Ag, 1.05% Cu, 0.58% Pb and 1.97g/t Au and inferred of 669,600 tonnes at 2.26% Zn, 32.99 g/t Ag, 0.90% Cu, 0.44% Pb and 1.90 g/t Au at a 1% Zn cut-off. NATIONAL INSTRUMENT 43-101 INDEPENDENT TECHNICAL REPORT10.07-2024. *
- The inventory files of the British Columbia government (MINFILE 092B 129) report the Lara Deposit as 528,839 tonnes grading 5.87% Zn, 1.22% Pb, 1.01% Cu, 100.09 g/t Ag and 4.73 g/t Au which has a reported source of the “George Cross Newsletter No. 188, September 29, 1992”.
- One massive sulphide lens exposed by trenching in the Coronation Zone graded 24.58 g/t Au, 513.6 g/t Ag, 3.04% Cu, 43.01% Zn and 8.30% Pb over 3.51 m. Repeated sampling of this trench returned very similar grades in 2006 and by portable XRF in 2024.
- The Coronation Trend consists of several stratiform massive sulphide lenses within an envelope of banded or laminated sulfides. The Trend is made up of three zones: the original discovery of the Coronation Zone, the Coronation Extension Zone (east and stratigraphically above the Coronation Zone) and the Hanging Wall Zone which consists of stringer mineralization that is also stratigraphically above the Coronation Zone (Roscoe and Postle, 1988).
- The Coronation sulphide mineralization exhibits variation in thickness from 3 to 16 metres, averaging about 6 metres (Crick, 2003; MINFILE, 1990a).
Overall Interpretation
The Coronation Zone, as outlined by historical drilling, contains significant massive and semi-massive sulphide grades and tonnes as well as over mineable widths (>2 m). It is the most significant VMS deposit outside of the Mt. Sicker deposits in the area and occurs at shallow depths of <150 m below surface. Previous metallurgical testing and pre-feasibility studies (Roberts, 2007; Broughton, 1987) although not current, demonstrate the possibility that the deposit can be economic and deserves further investigation. Furthermore, there is abundant exploration potential to depth and on strike along the Coronation Trend to warrant additional exploration as VMS deposits such of these tend to occur as clusters including the most immediate analogues (Mt. Sicker and Buttle Lake Myra Falls deposits).
Exploration History
Since the 1980’s substantial amount of exploration work has been completed at the Lara project with over 311 drill holes totalling more than 55,712 meters as well as 770 metres of pre-production underground access and drifting. The main resource, also known as the Coronation Trend was modeled using Datamine Studio as six discrete zones and consists of continuous pods of zinc and gold rich mineralization. The current resource estimate is based on the Coronation Trend, which includes the Coronation Zone, the Coronation Extension and the hanging wall deposit. In 2008, Caracle Creek International Consulting completed a historic resource for Treasury Metals Inc. described in an Independent Technical Report and Mineral Resource Estimation, Lara Polymetallic Property, April 2008 (Iain Kelso, H.B.Sc., P.Geo., and Stephen Wetherup, B.Sc., P.Geo., co-authors).

Mineral Resource Summary
1% Zn Block Cut-off*
2% Zn Block Cut-off
The historical estimate was prepared using wireframe models for zinc thresholds, with grade interpolation completed using the inverse power of distance method. The reliability of the historical estimate is considered reasonable, but a qualified person has not completed sufficient work to classify the historical estimate as a current mineral resource and the Company is not treating the historical estimate as a current mineral resource. To upgrade the historical resource to a current resource a constrained mineral estimation should be constructed by a qualified person. Nova intends to use this work to guide further exploration on the Lara Project.
With over 80% of this project remaining under-explored, we are excited to expand on an exceptional historical result and further develop this exceptional opportunity

Project Details
There exists strong potential to mine a high-grade, near surface, deposit Drill hole 87-182 was excluded from the database as its composite interval of 2.02 m @ 25.37% Zn, 200.3 g/t Ag, 5.88% Pb, 2.53% Cu, 4.43 g/t Au was found to unduly influence the grade of the entire Inferred category. The position of 87-182 is over 100 m from surrounding samples within the plane of the zone, and therefore a large number of Inferred blocks were influenced by this interval. Drill hole 87-182 terminates within a high-grade zone at a true depth of approximately 200 m; this portion of the Coronation Trend is an ideal location for definition drilling as this high-grade area is open immediately up-dip (~75 m) and across strike to the east-southeast.
Planned Exploration
Nova’s objective
Further Drilling and characterization
Characterize the existing mineralized zones by commencing further drilling within the mineralized zones to enhance the current resource. 40 short (~100-200m) drill holes within the Coronation zone over 4 phases for a total of 6,000m drilling.
Increase Resource Estimates and Discovery
In addition, there remains excellent potential to increase the current resource estimate and the discovery of additional massive sulphide mineralization by drilling at depth along strike of the already known mineralized zones.
In the late 1990s, the geological potential was projected to yield a multi-billion dollar deposit with similar grades and in a similar formation to the Buttle Lake Mine not far to the north of Lara. With Phase I exploration activities planned this year, we see real potential to increase the current resource estimate and at a significantly higher grade. Given today's metal prices, this could translate into a highly valuable mineral deposit.
