Nov 14, 2011 (A Wilson) - The mineralization is hosted within a conglomerate xenolith in a quartz feldspar porphyry lens. The lens which has been traced for 3 km, is 200 m wide.
Nov 14, 2011 (P Bousquet) - The gold mineralization is hosted the quartz-feldspar porphyry, accompanied with blue-grey quartz veins, disseminated fine sulphides and some tourmaline.

Dec 05, 2012 (A Wilson) - Assays from a grab sample collected by Denison Mines from an old trench returned a value of 0.011% Mo. Molybdenite occurs in patches within the conlgomerate xenolith's schistosity.
Jul 01, 2016 (P Bousquet) - Holes HL-07-01 and HL-07-02 intersected sections of the quartz-feldspar porphyry that returned assays to up to 1.645 g/t Au. The highest assays was in a section altered with sericite. More drillholes were drilled into the feldspar porphyry, returning assays to up to 5.29 g/t Au, 424 g/t Ag and 1.445% Mo.

Notes: Field Notes: In the company of 2 summer experience students, a site visit was made to examine the geology and outcrops in the vicinity of Huffman Lake. A series of outcrop observations follow: (All UTM locations are in NAD 83, Zone 17). Stop 1: 415669E, 5262827N. coarse grained granodiorite gneiss with gneissosity trending 154º. Stop 2: 415901E, 5262980N. Outcrop on the east side of the road contains a 3 inch wide granitic pegmatite dike crosscutting granodiorite gneiss. The dike trends due north. Stop 3: 416644E, 5263528N. Outcrop in road bed forms a large ridge of tonalite gneiss with gneissosity trending 090º. Stop 4: 423239E, 5261798N. (Namex Road) tonalite-granodiorite with foliation trending 072º intruded by a magnetic diabase dike of fine to medium grained gabbro. Stop5: 422125E, 5266809N. Fine grained mafic flows showing pronounced deformation, foliation trends 120º. Stop 6: 422121E, 5266913N. Pillowed mafic flows, small pillows are north facing, foliation trends 120º. Stop 7: 420845E, 5269636N. Outcrop on east side of the road consists of highly strained felsic tuff with a 1 m wide zone of pyrite mineralization. Felsic metavolcanics are thinly bedded on a 1 to 2 cm scale. Stop 8: 420683E, 5270814N. Stretched clast of matrix supported polymictic conglomerate, foliation trends 092º. Clast compositions include felsic volcanic, mafic volcanic and intermediate volcanic. The conglomerate matrix is chloritic with iron carbonate alteration. Soft sediment slump folds occur in an overlying sandstone bed with tops to the north. Glacial striae trend 165º . Stop 9: 417593E, 5273294N. Intermediate volcanic with high strain and dextral shear sense. Stop 10: 413834E, 5275781N. Beaver dam washout on road, passage not possible by vehicle. Stop 11. 416748E, 5273142N. pillowed mafic flows outcrop. Stop 12: 416200E, 5272350N. Location of Namex stripped, trenched, washed and channel sampled outcrops. Access is by a recent 1 km drill trail leading off the logging haul road. Overburden trenching has been completed on 5 trenches in the area immediately south of Huffman Lake. Intensely sheared sediments include metamorphosed conglomerate and sandstone. The conglomerate varies from clast supported to matrix supported and is polymicitc. Clasts include mafic volcanic, intermediate volcanic, felisc volcanic, quartz, feldspar porphyry and banded iron formation. Intruding the conglomerate is a quartz feldspar porphyry with indistict contacts due to alteration including iron carbonate, weak hematization and silicification. Foliation trends 105/75N. The company owned diamond drill was on site at the time of our visit as was the unoccupied exploration camp.
