Medicine Springs - Review of Rock Sample Results
Selected rock sample assays shown in Table 1 highlight the presence of high-grade silver zinc and lead mineralization on the Medicine Springs Project. (see full list of results shown in Appendix 1 to this news release). Note the selected rock samples are not necessarily representative of the mineralization hosted on the property or in the dumps. The rock sample QA/QC Procedures and Protocol for the samples is detailed in Appendix 1.

Northern Lights, Head of Geology, Gary Artmont commented: "The geological and geochemical characteristics of the Medicine Springs mineralization strongly suggest a distal carbonate replacement setting related to a concealed molybdenum porphyry system. The geochemical signature and style of mineralization observed at Medicine is similar to other carbonate-hosted, Ag-rich base metal veins, CRD and skarns deposits developed peripheral or above copper-molybdenum porphyry stocks."
As illustrated on Figure 1, a new base metal belt is emerging in northeast Nevada that includes the Medicine property. This belt contains a wide variety of mineralized settings including copper and molybdenum porphyries, proximal base metal skarns, distal CRD and Carlin disseminated gold deposits. The notable porphyry deposits include Mt. Hope and Robinson to the south of Medicine Springs and the West Butte and Spruce Mt. advanced prospects to the northeast of Medicine Springs.

As illustrated on Figures 1 and 2, surface mapping has defined 2 zones of alteration:
The northern zone is approximately 600 meter in length and up to 500 meters in width and has been tested by 117 very shallow RC drill holes (average depth 43 m); and
The southern zone encompasses the Silver Butte shafts and surface workings and measures 2300 meters in length and up to 800 meters in width.
Both alteration zones are hosted Permian sandy to silty limestones which are in part fossiliferous. The Golden Pipe mineralized trend has been identified in drill hole JS-105 which is located an additional 850 meters to the northeast into a colluvium covered salt pan.
The alteration zones are dominated by a sericite-carbonate-FeOx developed between a series of subparallel northeast trending faults which have in part controlled the emplacement of intrusive dykes. The alteration zones also contain fault-controlled jasperoids cut by late high-grade barite-zinc-lead-silver veins.
With reference Figure 3, a total 43 samples were collected from outcrop, shaft collars and mine dumps with the assay results summarized in Table 1 and Appendix 1. Silver assays ranged from less than 1 g/t to a maximum of 559 g/t (150 m west of Silver Butte north shaft) with 16 samples returning assays greater than 30 g/t. The best silver assays were obtained from dumps and shaft samples collected from the Golden Pipe and Silver Butte prospects. Silver is associated with high levels of barite, lead and zinc. Trace elements include anomalous values in As, Sb, Hg, Mn and Mo and weaker but still significant levels of Se, W, and Sr. As illustrated on Figures 3 and 4, the anomalous sample locations exhibit a good correlation with zones of high resistivity that appears to be related to sericite-carbonate alteration. The correlation with the intrusive dykes is poor possibly due to under sampling.
At the Medicine property, the carbonates exhibit weak hornfelsing and marbleization which is associated weak to moderate, irregular sericite-carbonate-FeOx alteration. This style of alteration appears to reflect a distal position peripheral to a concealed porphyry stock located somewhere on the property. Importantly, the trace elements that include Mo, Sr, and W indicate an intrusive provenance while Pb, Zn, As, Sb, Hg, Mn and Ag reflective a distal carbonate replacement setting similar to the Lone Mt. and Gunman base metal deposits located to the southwest.

With reference to Figure 4, the Taylor silver-rich lead-zinc deposit being developed by South32 in Arizona is situated approximately 2 kilometers to the east of the Sunnyside copper-silver porphyry stock. The Taylor mineralization is hosted by Permian carbonates that have been altered to calc-silicate skarns with minor copper and negligible gold values. Using Taylor's alteration pattern and geochemistry as geological analogue, the Medicine Springs oxide mineralization is located at a greater distance from the contact of a concealed porphyry intrusive stock.

Sample QA/QC Procedures and Protocol
All rock samples were collected by W. Tafuri PhD., consulting geologist to Northern Lights, during field examination of the Medicine Springs project during the months of August to November 2018.
A total of 45 samples were collected from outcrop and dumps located on the Property. Sample locations are indicated in Figure 2, above. W. Tafuri collected the rock material which was placed in olefin sample bags which were then delivered to ALS Global for sample preparation and analysis. After collecting, bagging, and sealing the rock samples in the field, the W. Tafuri maintained a rigid chain of custody before delivering the samples to ALS Global - Geochemistry Analytical Lab depot located in Elko Nevada.
The entire rock sample is dried, crushed to 70% passing 2 mm, and split and passed through a Jones Riffle Splitter to recover a 300-gram sub-sample which is then pulverized to 85% passing 75 microns. A 5-gram representative sub-sample is then collected from the 300-gram sample which is then digested with HNO3+HCl for two hours in borosilicate. The digested samples are read on a ICP-AES (Inductively coupled plasma atomic emission spectroscopy). The concentration of Pb-Zn-Ag, the metals of interest, are determined as part of multi element ICP package. Overage limits for these metals, if any, are then determined by a high-grade ore analysis (ICP) again using a 5-gram charge from the 300-gram sub-sample.
Due to the small sample population, no third-party certified standards are submitted with the samples but ALS Global document internal standards and blanks consistent with QA/QC protocols which are considered adequate by G. Artmont, the QP for this news release.
ALS Global is completely independent of the Qualified Persons described in this news release and in-turn, the Company, in all aspects. ALS Global is a fully-certified, internationally recognized analytical laboratory for the minerals industry.
