Little Nahanni Pegmatite Group Property (LNPG)

The Little Nahanni Pegmatite Property is in the NWT, adjacent to the Yukon border and
some 39km WNW of the Canada Tungsten mine. The prospect comprises 5,393 ha (53.93 km2) consisting of a system of branching swarms of dykes that extend over 13km exposed strike length and up to 500m width. Individual dykes within these swarms`are mostly 1-10m thickness. Natural exposure and drilling has demonstrated a vertical extent of 300m. Minerals of interest are spodumene, lithium micas, tantalite-columbite and cassiterite. Grades of up to 2% Li2O and 500g/t Ta2O5 are reported for individual dykes. The property has been explored sporadically since 1979. This work included soil and stream sediment geochemistry, chip and channel sampling of cliff faces and 1,798m of diamond drilling. With the current increase in the demand of Li and Ta the property has become a significant prospect. Equitorial Exploration Corp. optioned the claims in 2016 and commenced exploration with a carefully executed channel sampling programme that was performed by Archer Cathro and Associates (1981) Limited (Archer Cathro).

To date no estimate of reserves that would be NI 43-101 compliant has been made. Future work would be best aimed at developing adequate grade data. The 2016 channel sampling is adequate for inclusion in a database of dimensions and grade. Further sampling using accurate surveying and documentation is needed. The property is large enough that many diamond or percussion drill holes will be required to build up a compliant resource. These may best be sited according to results of surface channel sampling. Testing of the mineralization at depth is also an obvious target.

2016 Sampling Program
In 2016 Archer Cathro carried out channel sampling across the various main pegmatite zones on behalf of Equitorial Exploration (Figure 9). Equitorial`s September 6, 2016 news release stated:
“During the 2016 field program, a total of 81 channel samples were cut across dyke swarms in two cirques (3 and 4) on the LNPG property. The samples were cut using a hand-held rock saw. Channel samples are considered the most representative way to test surface exposures and are akin to diamond drill core in size and purpose. Channel samples were collected from the Prison Wall, Berlin Wall, Great Wall of China and Hadrian’s Wall dyke swarms within cirques 3 and 4. Highlights from individual dykes within and adjacent to dyke swarms include:

  • 1.57% Li2O, 250.3 g/t Ta2O5, 0.95% SnO2 across 1.70 m
  • 2.04% Li2O, 57.8 g/t Ta2O5, 0.05% SnO2 across 4.00 m
  • 3.10% Li2O, 53.6 g/t Ta2O5, 0.03% SnO2 across 0.95 m
  • 2.33% Li2O, 59.0 g/t Ta2O5, 0.05% SnO2 across 1.20 m
  • 1.67% Li2O, 41.4 g/t Ta2O5, 0.03% SnO2 across 3.75 m
  • 1.83% Li2O, 67.3 g/t Ta2O5, 0.05% SnO2 across 1.25 m
  • 1.63% Li2O, 52.9 g/t Ta2O5, 0.01% SnO2 across 5.15 m

The dykes are separated by sedimentary wallrocks including quartz sandstone, limestone and shale, which do not contain significant amounts of any elements of interest. Weighted average grade calculations for channel sampled intervals are reported in the following paragraphs. Wallrock separating individual dykes within dyke swarms was sampled in Cirque 4, and the values reported were uniformly low. When calculating weighted average grades for the dyke swarms, the wallrocks were assigned zero values for all elements. Weighted averages reported for dyke material within the dyke swarms omitted wallrock dilution.

Prison Wall
A 16.80 m interval was channel sampled across an exposed portion of the Prison Wall on the
north side of Cirque 4. The weighted average grade across this interval was 0.29% Li2O, 14.4 g/t Ta2O5 and 0.01% SnO2 over 16.80 m, including a total of 4.4 m of dyke material that graded 1.12% Li2O, 55.0 g/t Ta2O5 and 0.05% SnO2.

Two individual dykes located 13 m and 27 m north east of the dyke swarm were also sampled, and they returned 0.87% Li2O, 56.4 g/t Ta2O5and 0.03% SnO2 across 1.90 m and 1.57% Li2O, 250.3 g/t Ta2O5 and 0.95% SnO2 across 1.70 m, respectively.

Berlin Wall
A 35.80 m interval was channel sampled across part of the Berlin Wall on the north side of Cirque 4. This interval yielded 0.29% Li2O, 12.3 g/t Ta2O5 and 0.01% SnO2 across 35.80 m, with dykes within it averaging 1.50% Li2O, 63.9 g/t Ta2O5 and 0.05% SnO2 across a total of 6.90m. The best individual dyke within the dyke swarm returned 2.04% Li2O, 57.8 g/t Ta2O5 and 0.05% SnO2 over 4.00 m.

On the south side of Cirque 3, a portions of the Berlin Wall swarm returned 1.00% Li2O, 21.3 g/t Ta2O5 and 0.01% SnO2 across 4.45 m, including 1.95 m of dyke material that graded 2.29% Li2O, 48.7 g/t Ta2O5and 0.01% SnO2.

Great Wall of China
A 52.60 m interval across the Great Wall of China on the north side of Cirque 3 returned a weighted average grade of 0.38% Li2O, 20.7 g/t Ta2O5 and 0.01% SnO2. Within the 52.60 m interval, fourteen individual dykes were sampled a total thickness of 16.65 m. The combined
thickness of the dykes graded 1.21% Li2O, 65.4 g/t Ta2O5 and 0.03% SnO2.

A 19.70 m interval across a portion of the Great Wall of China on the south side of Cirque 3
averaged 0.50% Li2O, 21.3 g/t Ta2O5 and 0.01% SnO2 over 19.70 m, including four dykes totaling 7.00 m that graded 1.41% Li2O, 59.9 g/t Ta2O5 and 0.04% SnO2.

An individual dyke located 77 m east of the Great Wall of China dyke swarm on the south side of Cirque 3 returned 1.63% Li2O, 52.9 g/t Ta2O5 and 0.01% SnO2 over 5.15 m.

Hadrian’s Wall
A 10.35 m wide portion of Hadrian’s Wall was sampled on the south side of Cirque 3. This interval returned 1.13% Li2O, 71.1 g/t Ta2O5 and 0.03% SnO2 over 10.35 m. Within that interval, dyke material graded 1.86% Li2O, 116.7 g/t Ta2O5and 0.05% SnO2 across 6.30 m.

Twenty-five metres west of the 10.35 m exposure of the Hadrian’s Wall dyke swarm, two additional dykes returned 0.85% Li2O, 80.9 g/t Ta2O5and 0.05% SnO2 over 1.05 m.”

43-101 – Interpretation and Conclusions
The Little Nahanni pegmatite prospect contains a system of Lithium-Caesium-Tantalum-
type pegmatite dykes that crop out over a strike length of 13km in seven separate groups within the present property boundary. Spodumene and to a lesser extent the micas are potential lithium sources. Accessory tantalite-columbite and cassiterite contents have sufficient grades to bring the rock to within potentially economic values. Continuity of the dykes over a vertical range of 300+ metres is demonstrated by natural exposure and past drilling. So far the greatest thickness of a single dyke encountered is ≈10m, encountered in drill holes 6 and 7. The thickness of each`swarm`of dykes is up to 300m. The most reliable channel sampling has been that performed in 2016. Careful measurement of dyke width and host rock intervals have enabled bulk grades tobe calculated. Such results as 10.35m at 1.13% Li2O, 71.1 g/t Ta2O5 and 0.03% SnO2 are highly encouraging.

The pegmatite system has not been investigated to depth. The potential exists for dykes to coalesce below the level of the lowest cirque and grade could well be different. Closer to the postulated buried intrusive source for the pegmatite beryl could become significant. There is also the possibility that greisen has been developed in the upper portion of the granite, with potential for Sn and W. Drilling of several deep holes along the extent of the system is desirable.

43-101 – Recommendations
The author of the 43-101 considers the following recommendations, made by Heather Burrell of Archer Cathro to the Company in September 2016 to be very pertinent and still relevant: “The following steps would be beneficial for the advancement of the LNPG property:

  1. Transportation of the 2007 diamond drill core from its current storage location near Finlayson Lake to Whitehorse;
  2. Re-logging of the diamond drill core to determine if dyke material was blended with sedimentary wallrock material or if some dykes were not sampled. This would allow us to confirm how the previously reported drill results compare to the channel sampling completed in 2016;
  3. Data input and interpretation of the 3D survey information that was collected by the previous operator;
  4. Systematic prospecting and channel sampling throughout the property;
  5. Investigation of pre-sorting technologies to separate mineralized dyke material from wallrock waste;
  6. Relationship building with the Nahanni Butte First Nation;
  7. Permitting the land use application for advanced exploration activities on the LNPG property; and,
  8. Diamond drilling near previous holes and the best channel sample locations.“

Tule Valley Lithium Brine Project

The Tule Valley Project consists of 26 claims of 26 acres each and is located approximately 190 south westof Salt Lake City, Utah. The property straddles Juab and Millard counties. Access is by a all weather, hard surface highway from Delta, Utah and from Wendover, Nevada or by a paved road to the south. Further access is by gravel roads in fair condition.

The terrain is readily amenable to the construction of the necessary infrastructure related to mining operations. This includes, but is not limited to, potential tailings storage sites, potential waste disposal areas, heap leach pad areas and potential processing plant sites It would be necessary to access electrical power from Gold Hill or Callao (Lee, 2003).

Tule Valley Lithium Project

Surrounding area is sparsely populated, with ranching and livestock being the primary economic activities. The Tule property is located 20 km south of Redhill Resources Honey Comb-Beryllium-Rubidium, Lithium and REE project. It is approximately 60km to the northwest of the Crystal Peak potash, lithium and magnesium project and 30 Km to the south west of Matererion’s Spor Mountain Beryllium Mine.

Tule Valley Lithium Project

The basins in this area are defined as arid, generally receiving less than 8” of precipitation per year. Evaporation exceeds precipitation with hot dry summers and cold dry winters.

Closed Basin
Tule valley is an endorheic basin, which means that it retains water but does not allow any external outflow. This means that any element that mobilizes into the basin, can enter but never leaves. This poses the hypothesis that over millions of years the aquifer may have upgraded into an extremely mineralized brine.

Tule Valley Lithium Project

Similar to that of Clayton Valley, Tule Valley is a closed basin and has a horst and graben structure. The valley is down faulted by normal faults on both sides of the valley. This is a key characteristic for confining brines so mineralization cannot escape.

Tule Valley Lithium Project

The area to the north contains volcanic rocks such as rhyolite flows and tuffs ranging in age from 3.4-4.7 Ma and are known to contain significant values of lithium, beryllium, rubidium and REE’s. Chemical and mineralogical studies of samples from shallow excavations and drill holes revealed abnormal quantities of cesium, rubidium and lithium in the beryllium-bearing tuffs. (Stonehouse, 1985).

Results from the soil grid suggest that lithium (Li), beryllium (Be), rubidium (Rb) and TREO (total rare earth oxides), including lanthanum to lutetium plus yttrium) mineralization may be present under shallow cover to the east flank of the Big Honey Comb Hill.

Tule Valley Lithium Project

Honeycomb Hills are two domelike bodies of rhyolite with a total volume of 0.5 km3, contained within an area approximately 1.5 km in diameter. Basaltic lava flows surround the area (Hogg, 1972), and tuffs adjacent to the rhyolite contain high concentrations of Cs, Rb, Li, Be, and F (McAnulty and Levinson, 1964).

Erosional History
During the 130,000 to 10,000 year period of pronounced glaciations and inter-glacial flooding, erosion of the Deep Creek granitic highlands, west and adjacent to the paleo-shorelines, provided detrital feed for the paleo-beaches of Bonneville Lake basin. Granite grit, containing
magnetite and associated heavy minerals, including rare earth-bearing minerals, became feed for the beaches. This erosional debris was distributed, worked and re-worked as the shorelines advanced and receded.

2009 Assay Results
In 2009, the underlying vendors have completed detailed geological mapping, prospecting and collected 146 total samples (including blanks) with significant values of beryllium returned, along with anomalous values of lithium and uranium. Initial surface sampling (146 samples) have reported assays of up to 1,043 ppm total rare earth oxides (TREO), 1,690 ppm lithium (Li), average of 1,010 ppm beryllium (Be) and 1,270 ppm rubidium (Rb). Detailed mapping has shown an anomalous area of roughly 500 by 1,000 m with another neighboring anomalous area of 500 by 500 m. In addition, both anomalies are flanked by quaternary alluvium and could extend substantially under shallow cover. In addition, sampling and mapping of a decline excavated in rhyolite breccias show highly anomalous Li, Rband weakly anomalous TREO assays from 460-1050 ppm, 471-1035 ppm, and 392-461 ppm respectively.

2016 Assay Results
A total of four water samples and 13 soil samples were collected from the property. The soils were crushed, pulverized and assayed for lithium and a suite of pathfinder elements (for example, potassium, magnesium, barium, sodium, calcium, lithium-potassium and lithium-magnesium ratios). Most soil samples were collected at the claim post sites that were located on exposed playa.

Samples of actively evaporating briny surface muds are all anomalous in lithium (over 0.01 per cent lithium). Each of these anomalous samples is very wet, saturated with salty brine, contains salt and/or gypsum crystals, and lies below 1,340 metres altitude. These locations are where the playa surface dips below the current groundwater table (less than 1,339 metres), wherein near-surface brines reach the surface, form shallow pools (less than 0.3 metre deep), and evaporate. The western half of the playa seems to lie at a lower altitude than the eastern half. The fact that both the surface brines (W03 and W04) and resultant saturated muds are anomalous in lithium is deemed encouraging for the deposition of near-surface lithium mineralization on the property.

Gerlach Lithium Brine Project

The Gerlach project is comprised of 89 claims, 720 hectares (1,780 acres), located in the San Emidio desert, 5 miles from Gerlach, Wahoe County, Nevada and 120 km north of Tesla Gigafactory #1. The property is located within the southern lobe of the Black Rock Desert, a graben feature of the Basin and Range geological province which is dominant throughout Nevada.

“San Emidio Desert in northern Nevada is geothermally active”

San Emidio Desert
San Emidio Desert is the name given to the playa extending south from Gerlach and it is the southern “tongue” of the largest dry lake bed in North America (Black Rock Desert). San Emidio is a dry lake bed (playa), its edges are covered with a thin veneer (up to 3 m) of wind-blown sand dunes and mounds. In this respect, San Emidio is not a pure evaporite basin, such as Great Salt Lake, Sevier Lake, or the Bolivian and Chilean salars, where active evaporation and salt/phosphate-deposition (±Li) is on-going.

Gerlach Lithium Project

“NAIP image showing surficial hydrothermal alteration and the Wind Mountain epithermal deposit in orange, and the geothermal power plant in black. The San Emidio Desert is bounded to the west by the Fox Range and to the east by the northern Lake Range.”

Although composed of dried mud/silt/ash, the compacted playa mud is salty (indicating some form of evaporation during the life of the playa). In this respect, the San Emidio playa may be more appropriately compared to the Clayton Valley. Country rock along the eastern margin of the playa has been hydrothermally altered (e.g. Empire Gypsum deposit, Wind Mountain epithermal Au/Ag deposit), suggesting high heat flow and intense groundwater flow. This activity would have leached lithium where present.

Gerlach Lithium Project
“San Emidio Desert in northern Nevada is geothermally active”

All well-known natural hot springs in the region occur to the north and northeast of the town of Gerlach. These springs are located adjacent to the Black Rock Desert, and may feed its groundwaters, and those of the San Emidio basin.

Gerlach Lithium Project

More important for Umbral’s property is the presence of US Geothermals’ electro-generation plant located 27 km south of the G01-89 claims on the eastern edge of the southern lobe of the San Emidio playa. This confirms the presence of geothermal activity (hence brines) in the San Emidio playa, which appears to be a closed valley, may have lithium-bearing clays and/or ash in its sediments, has active, hot, lithium bearing groundwater flow along its eastern margin (US Geothermal, gypsum mine, etc), and has been affected by evaporite-style processes. The San Emidio property may therefore be conducive to the presence of lithium-bearing groundwater.

Upcoming Exploration
Gerlach exploration is expected to focus initially on geophysical surveying,particularly IP, to detect conductive layers beneath the playa floor. Brines are salty, and are therefore strongly conductive. The thicker and strongest conductive zones can subsequently be drill-tested for lithium content. Further research into the distribution of active hydrothermal activity along its eastern edge is also required.
