BEDFORD, NS / ACCESSWIRE / November 29, 2022 / Silver Spruce Resources Inc. (the "Company") (TSXV:SSE)(OTCQB:SSEBF) is pleased to announce technical services agreements with Eagle Mapping Ltd. ("Eagle Mapping") of Port Coquitlam, British Columbia, and GeoCloud Analytics of Melbourne, Australia to carry out an airborne LiDAR survey and re-process the LASer (LAS) point cloud data, respectively, over the Melchett Lake Zn-Cu-Au-Ag volcanogenic massive sulphide project ("Melchett" or the "Property"). Melchett is an advanced precious and base metal property located in the Thunder Bay Mining District, northern Ontario, Canada (the "Property"). The Property lies 110 km north of Geraldton and 60 km north of Nakina.

"We continue to steadily advance our exploration program for polymetallic targets at Melchett Lake and were pleased to schedule the LiDAR survey during October to complete data collection in only one flight day over the entire Property," said Greg Davison, Vice-President Exploration and Director of Silver Spruce. "The LiDAR program is to define, using re-processing of the Eagle Mapping LAS point source data by GeoCloud Analytics, major to subtle structural features, archaeological sites or features proximal to the Kapikotongwa-Melchett-Nass Lakes waterway south of the Property, and more detailed topographic control for access routes and drilling collar locations. Pending project financing and contractor scheduling, line-cutting by Pleson Geoscience will be performed during Q2 2023 to be followed by the Quantec Geoscience ("Quantec") deep-penetrating SPARTAN Magnetotelluric ("MT") survey."
"The principal target area for the program has extensive soil and rock geochemical anomalies, known VMS style mineralization from surface to >500 metres depth, highly favorable alteration type and intensity, increasing Cu to Zn with depth, and deep Maxwell modelled plates off-hole from borehole EM surveys, stated Mr. Davison. "The 2021/2022 MPX airborne survey complemented our project ArcGIS database with state of the art, high resolution data over these promising targets extending through several historical gold, silver and base metal showings and geochemical anomalies identified on the eastern and western claims."

The recent In3D Geoscience interpretative maps (see Figures 2 and 3) clearly identified numerous structural details associated with folding, with tight, plunging and linear limb features, several generations of faulting and intrusions likely transecting the older base metal and gold mineralization, moderate to deep continuity of the magnetic features associated with the known areas of mineralization shown particularly well at Relf Lake. Several additional patterns coincident with or along strike with 2002 EM anomalies, particularly along the northern zones north of the Nakina showings and west towards the Key Lake targets. Potential folding of said units, potential stacking and/or fold repetition of EM anomalies may be associated with the core of the Relf Lake target area and the Nakina 1 and 2 targets, and clarity of dextral (imbricate) offsets related to the strike breaks of known geochemical and geological anomalies among others.

Eagle Mapping LiDAR, Data Processing by GeoCloud Analytics
The LiDAR data is expected to complement the detailed geophysical interpretation recently completed by In3D Geoscience as outlined above, and currently available field geological data.
Eagle Mapping collected LiDAR data and aerial photography from the area, shown in Figures 1 and 2, at a nominal flight elevation of 5000 feet (1500 metres) at a minimum density of 8 ppm (pulses/m2) with expected accuracies of ±15 cm in the vertical and ±30 cm in the horizontal. Colour aerial photography will be orthorectified to the LiDAR base earth model with a 12 cm pixel resolution. Digital elevation (DEM) and digital surface (DSM) models with contours at 1 metre will be generated.
The LASer (LAS) point cloud with classified bare earth and metadata final report will be contained in the deliverables. The LAS format is an open binary file format designed for the interchange and archiving of LiDAR point cloud data and regarded as an industry standard for LiDAR data.
The Eagle Mapping aircraft mobilized from Thunder Bay, Ontario upon receipt of all requisite flight permits. The LiDAR surveys were completed on schedule during October 31st, 2022. The final survey data are in processing and standard turnaround is estimated at two months.
GeoCloud Analytics will provide the following data services on the Eagle Mapping data package with processing, and interpretation with PowerPoint deck, expected to require four weeks from receipt:
- Reprocessing of LiDAR to enhance and extract ground model detail
- Mosaiced products on the project area basis at resolution* defined by existing data:
- ground model (DEM) at 50cm* resolution in GeoTiff format
- ground model hillshade at 50cm* resolution in GeoTiff format
- reprocessed enhanced hillshade at 50cm* resolution in GeoTiff format
- Interpretation of LiDAR to derive:
- mining evidence e.g., adits, shafts, pits, trenches, etc.
- geological contacts e.g., bedding, faults, folds, shear zones, etc.
Property Highlights
The Property covers 5,022 hectares (168 single cell mineral claims and six multi-cell mineral claims) with VMS and Au targets located in east to southeast-striking, tightly folded, subvertical to moderately north-dipping Archean metavolcanic quartz-sericite schists. These units exhibit steep down-dip to southeast raking or plunging lineations. The Melchett Lake belt contains several occurrences of polymetallic Zn-Pb-Cu-Ag-Au VMS mineralization similar in several respects to deposits exploited at Geco, Mattabi, and Winston Lake, among others.
Highlights of the prospective geology, alteration and mineralization include a strike extent of more than 20 km, multiple folded or stacked horizons of coincident alteration and metal mineralization, high Zn/Cu, Zn/Pb and Ag/Au ratios, increasing Cu/Zn at depth, extensive remobilization of major and trace elements with defined enrichment (Fe, Mg, Co, Cr, Cd) and depletion (Na, Sr, Ca) zones.
Figure 4. 30m x 40m gossan zone exposure of moderate to steeply north-dipping zinc (Fe-sphalerite) mineralization in quartz-sericite-pyrite schist from the main trench in the Relf Lake Zone.
Surface trenches, with Fe-sphalerite (blackjack or marmatite), contain locally high-grade lenses of Zn & Ag with variable Cu, Au and Pb, and historical gold grades to 28.8 g/t Au, silver grades to 560 g/t Ag and zinc grades to 19.1% (see Figure 4).
The claims to the east and west of the core Relf and Nakina targets cover 11 kilometres of known extensions of the Melchett Lake mineralized horizons and include high potential VMS and Au targets located along sub-parallel isoclinal fold limbs offset by oblique, imbricate structural breaks interpreted from recently acquired exploration MAG, VLF and GEOTEM data. Only limited and shallow exploration drilling was conducted in the Key Lake area (west) and Iron Lake area (east).
