Projects

Sentinel Resources’ guiding principles are based on acquiring strategic exploration properties in world-class mining jurisdictions with a rich history in mining, low-cost of entry or acquisition, and easy access to infrastructure to minimize capital and operational costs in explorational periods.

Hill End South Gold Project

Sentinel has acquired, by staking, three gold-focused licenses located in New South Wales, Australia. The three Gold Projects are known as Hill End South, Toolom South and Golden Bar.

Highlights of the Gold Projects:

Hill End South

This concession, covering an area of 84 km², is located within the highly prospective Hill End Trough and lies along the southern strike extension of the Hill End anticline and fault which host the highly productive orogenic lode style Hill End gold trend to the north.

The southern extension of the Hill End anticline has been less intensively explored than the northern part and provides an opportunity to discover unexposed saddle reef-style mineralization similar to that at Hill End. In addition, a substantial outcropping quartz lode has been reported but no gold assays are available. This will be an early focus of fieldwork.

Golden Bar

This concession covers an area of 198 km2 and is located in the eastern part of the New England orogen covering the majority of the historic Orara-Coramba gold field. There are at least 50 historic underground mines and prospects — many noted for high gold grades.

Forty-seven of the mines and occurrences in the New South Wales Government database are listed as structurally controlled, low sulphide hydrothermal-metamorphic vein-type deposits. Historic production records cite grades of up to 184 g/t Au. Occurrences are clustered along two east-west trending mineralized corridors with a cumulative strike length of over 40 km.

Of special interest are the historic workings at Bobo and Black Bull where wide and potentially laterally extensive zones of mineralization are reported, together with high gold grades.

Toolom South

Toolom South is located in the historic Toolom goldfield. It covers an area of 165.5 km2 and includes over 60 historic gold mines and high-grade gold showings. There are also potentially significant alluvial gold deposits.

Three groups of historic workings at Bucklands Reef, Reliance Mine and Rileys Lode with reported grades up to 104 g/t Au have been selected for early attention. At Bucklands Reef historic workings are reported to extend for 400 metres and these potentially provide a drill target following confirmatory field inspection.

Carrington Silver Project

Sentinel has an exploration license for the Carrington Silver Project located in New South Wales, Australia.

Highlights of the Silver Project:

Carrington is a 48 km² concession located in the East Lachlan orogenic terrane. Three high grade historic silver/gold mines and prospects are associated with the regional Yarralaw Fault. Although initially included with a group of silver prospects, the presence of high gold assays from historic work make this an equally attractive target.

The historic Carrington mine comprises extensive historical shafts and opencut drifts which exploited laterally extensive mineralized gossans that are up to 6 m wide. Historic rock chip samples returned grades of up to 85 g/t Au, 6037 g/t Ag, 24.8 % Pb and 16.8 % Sb. Interpretation of previous soil sampling results defines two high priority gold-bismuth-antimony anomalies along the historic workings which may be upgraded to drill targets after field confirmation.

The Salama Gold Project consists of four gold focused exploration concessions totaling 2,700 hectares in the Anta province of Peru. Preliminary review indicates extensive areas of quartz veins with localized silicified breccias, that have been the focus of historic production by artisanal and small-scale miners. These miners targeted high grade areas where oxidation of bedrock resulted in formation of free gold amenable to gravity recovery.

Preliminary review of regional satellite imagery indicates that two major structures intersect in the northeast of the concession, in a similar geological setting to La Virgin gold mine 20 km to the north. Historic production at La Virgin was reported as 120 Koz Au/annum.

Sentinel’s field team will initially comprise three in-country geologists, allowing for rapid first pass reconnaissance and rock-chip grab sampling. The field team has robust project review and target generation experience, especially with respect to Peruvian low and high sulphidation epithermal deposits, such as Lagunas Norte, La Arena and Rosario De Belen. This will allow mineralization at Salama to be placed within the wider context of an epithermal deposits geological, structural and hydrothermal evolution, and thus allow key controls on mineralization and high value targets to be rapidly established. Sentinel will submit samples to ALS Lima for preparation and analysis.

Potential for high and low sulfidation epithermal gold mineralization and breccia pipe stock-work style gold-silver deposits.

Situated within the prolific gold-polymetallic Miocene skarn and porphyry belt — one of several coast-parallel metallogenic belts that host the larger and more significant deposits of Peru (Figure 1). This includes Lagunas Norte Gold Mine, Rasario De Belen Gold Mine, La Arena Gold Mine and La Virgen Mine, that together host over 20 Moz gold within a 45 km radios of the Salama Concessions.

Highly experienced national and expatriate exploration team capable of carrying out exploration work on Salama Gold Project immediately.

First reconnaissance visit planned for the week of 12^th October 2020. First pass mapping and sampling will concentrate on areas of alteration hosting quartz veins and silicified breccias. Previous work by artisanal and small-scale miners provides additional vectors to areas of higher-grade mineralization.

Road accessible 3,130 Ha property, 65 km east of Kelowna, BC

Historic small-scale production from high-grade silver and high-grade gold prospects since the early 1900s (Waterloo mine, AU showing).

High-grade prospects define a 4 km E-W strike. Has never been systematically drill tested.

Carbonate Replacement Deposit (CRD) model fits with known mineral occurrences (porphyry to skarn to base-metal sulphide replacement to epithermal) – needs testing.

Potential for high grade low cost Ag + Au resource development

The Waterloo property is underlain by Mesozoic Quesnel Terrane rocks that also host nearby porphyry-Cu+Au deposits (New Afton, Ajax, Copper Mtn.), Cu-Au skarn (Phoenix), mesothermal-Au (Greenwood camp), polymetallic Pb-Zn-Ag (Slocan camp) and epithermal-Au (Knob Hill – Washington)

The Waterloo property has documented polymetallic Pb-Zn-Ag, mesothermal-Au, epithermal-Au, Cu-skarn and porphyry-Cu related mineralization

Property is underlain by a roof pendant of metamorphosed limestones, sediments and volcaniclastic rocks of the Harper Ranch Group (green) hosted in Jurassic-Cretaceous granites and granodiorites (pink).

High grade Ag-Zn-Pb mineralization along main E-W Waterloo structure (Grey). High grade Au-Pb-Cu mineralization along crosscutting N-S structures (Black).

High-grade mineralization has seen local historic production but no systematic drilling besides 12 short holes focused at Waterloo by Tower Resources. All targets are open at depth and along strike.

Genetic ore deposit model of mineralization peripheral to porphyry-related systems applied to Waterloo property

A. Porphyry – Pilot

B. Skarn – Richrock and VQ

C. Carbonate replacement – E-W Waterloo structure

D. Mesothermal veins – N-S Au structures

E. Epithermal – Potosi

This complex model has yet to inform exploration targeting at Waterloo – offers new opportunities.

Property scale structural mapping, soil geochemistry and IP geophysics is warranted followed by diamond drilling.
