The Nel occurrence is located 16 kilometres east-northeast of Aiken Lake, approximately 95 kilometres northwest of the community of Germansen Landing.

Assessment Report 4880 reports "two narrow pockets of rusty, highly leached gouge(?) material of only a few inches width...from which a grab sample assayed 0.24 gram per tonne gold, 185.2 grams per tonne silver, 0.38 per cent copper, 1.39 per cent lead and 3.15 per cent zinc. No sulphide minerals were identified, and bedrock is reported to be muscovite quartz schist of the Neoproterozoic Ingenika Group (Swannell Formation).

Geological Survey of Canada Memoir 274 (page 200) reports small veins containing galena, tetrahedrite and ruby silver (pyrargyrite) in quartzites and schists south of Mount Lay. Assessment Reports 15840 and 11204 report quartz mica schist hosting narrow, crosscutting vuggy veins and breccias carrying pyrite and possibly chalcopyrite with silver minerals (tetrahedrite, argentite and minor pyrargyrite). The veins strike 040 degrees, dipping 32 to 50 degrees southeast. Silicification and sericite-pyrite alteration is evident in the vicinity of the veins which are also weathered and altered to clay. Hostrocks are schistose quartz-biotite-muscovite schists with thick concordant quartz layers, cut by granophyre (felsite) dikes (Assessment Report 15840).

In 2016, a rock chip sample (L16-BL02) from a 5-25 centimetre wide quartz vein (010 degrees strike/60 degree east dip) mineralized with 1-2 per cent pyrite and locally up to 3 per cent dull grey sulphides assayed 0.54 gram per tonne gold, 870 grams per tonne silver, 0.22 per cent copper, 0.48 per cent lead and 0.73 per cent zinc (Assessment Report 36313).

In 1991, samples were collected of the area in which silver mineralization had been established. All of these samples proved to have silver values varying from anomalous to ore grade. Silver values were generally greater than 100 parts per million. Sixteen samples were anomalous in gold (greater than 200 parts per billion) as determined by Atomic Absorption (Assessment Report 22327).

During 1998, Canasil Resources Inc. conducted a program of rock and soil sampling; 29 rock samples and 27 soil samples were collected. Analysis of samples from the creek showings proved that better grade silver assays occurred in veins that have walls of quartzite or granophyre (Assessment Report 25945).

In 2001, Canasil Resources Inc. obtained a 35-kilogram ore sample from three locations on the Lil property. Silver recoveries of 94 to 98 per cent were obtained (Assessment Report 26861). No work was conducted on the property until 2011, when Canasil Resources Inc. completed an assessment of the narrow high-grade silver veins that comprise the Nel prospect. One of the veins samples, L11-BR01, yielded a result of 1159.6 parts per million arsenic and 153.5 parts per billion gold. A float sample in the creek, L11-BR03, returned results of 66.1 parts per million silver, 288 parts per billion gold and 2059.8 parts per million arsenic (Assessment Report 32641).

In 2012, a remote sensing survey of the Lil property was completed by Auracle Geospatial Science Inc. The assessment identified a number of mineralogical anomalies that, in part, provided some direction for 2013 fieldwork. In 2013, a brief prospecting program was conducted mainly in the northwestern part of the property. Results from the program were generally disappointing, but there were two exceptions: a chalcopyrite-bearing quartz-calcite vein up to 1.4 metres wide yielded assays of up to 7890 parts per million copper, and a limonite-barite zone within altered limestone grading greater than 10,000 parts per million barium and 295 parts per million zinc. The conclusions drawn from the work program were that the anomalous zones discovered in 2013 warrant further assessment and should be re-evaluated as part of a larger exploration program that includes detailed mapping and sampling of the Nel prospect high-grade silver veins in order to confirm appropriate drillhole locations. In 2014, the collection of satellite data was initiated over the Lil property via two Airbus 50 cm resolution satellites (Pleiades 1A and 1B). Data collection attempts through September and October were unsuccessful and Canasil decided to collect an additional set of data at a later date.

In 2016, on behalf of Canasil Resources Inc., one helicopter-assisted field day was spent on the Lil property. The high-grade veins which comprise the Nel showing have been the focus of intermittent exploration since their discovery. A traverse along the bottom of the canyon on its southeast side, where bedrock is discontinuously exposed, lead to the identification of five narrow quartz-sulphide veins. The veins range from 5-25 centimetres wide, trend north-northeast and dip moderately to steeply to the northwest. Some of the veins coincided with, and served to accurately locate, cut channel samples that were taken by Canasil in much earlier programs. The samples yielded anomalous to high-grade values of silver (2.6 to 870 grams per tonne) with anomalous levels of gold, copper, lead, and zinc. A conspicuous fault was observed on the west canyon wall that follows the approximate trend of the canyon and dips 45-60 degrees to the west. It places unmineralized Ingenika Group rocks on top of mineralized Ingenika Group rocks that are exposed, and were sampled, on the southeast side of the creek. Therefore, the potential for discovery of any additional veins at surface appears to be limited to the area southeast of the canyon (Assessment Report 36313).
