MEDICINE SPRINGS: REVIEW OF ROCK SAMPLE RESULTS
Northern Lights Resources Corp. has released the assay results and interpretation of surface
rock sampling, completed from August to November, 2018, on the company's Medicine
Springs project in Elko county, Nevada.
Selected rock sample assays shown in the attached table highlight the presence of high-grade silver,
zinc and lead mineralization on the Medicine Springs project. Note the selected rock samples are not necessarily
representative of the mineralization hosted on the property or in the dumps.

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, silver-rich base metal veins, CRD
and skarns deposits developed peripheral or above copper-molybdenum porphyry
stocks."
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 Mount Hope
and Robinson to the south of Medicine Springs and the West Butte and Spruce Mountain
advanced prospects to the northeast of Medicine Springs.
The northern zone is approximately 600 metres in length and up to 500 metres in width
and has been tested by 117 very shallow reverse circulation drill holes (average depth of 43 metres).
The southern zone encompasses the Silver Butte shafts and surface workings and
measures 2,300 metres in length and up to 800 metres 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 metres 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 dikes. The alteration zones also contain fault-controlled
jasperoids cut by late high-grade barite-zinc-lead-silver veins.
A total of 43 samples were collected from outcrop, shaft collars
and mine dumps with the assay results summarized in the attached table. Silver
assays ranged from less than one gram per tonne to a maximum of 559 g/t (150 metres west of the 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 arsenic, antimony, mercury, manganese and molybdenum and weaker but still
significant levels of selenium, tungsten and strontium. The correlation with the intrusive dikes is poor
possibly due to undersampling.
At the Medicine property, the carbonates exhibit weak hornfelsing and marbleization,
which are 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 lead, zinc, arsenic, antimony, mercury, manganese and silver
reflective a distal carbonate replacement setting similar to the Lone Mountain and Gunman base
metal deposits located to the southwest.
The Taylor silver-rich lead-zinc deposit being developed by
South32 in Arizona is situated approximately two kilometres 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 a geological analogue, the
Medicine Springs oxide mineralization is located at a greater distance from the contact of
a concealed porphyry intrusive stock.

Sample quality assurance/quality control 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.
The geologist 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 geologist maintained a rigid chain of custody before delivering the samples
to the ALS Global Geochemistry Analytical Lab depot, located in Elko, Nev.
The entire rock sample is dried, crushed to 70 per cent passing two millimetres, and split and passed
through a Jones riffle splitter to recover a 300-gram subsample, which is then pulverized
to 85 per cent passing 75 microns. A five-gram representative subsample 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 an ICP-AES (inductively coupled plasma atomic
emission spectroscopy). The concentration of Pb, Zn and Ag, the metals of interest, is determined as part of the multielement ICP package. Overage limits for these metals, if any,
are then determined by a high-grade ore analysis (ICP), again using a five-gram charge from
the 300-gram subsample.
Due to the small sample population, no third party certified standards are submitted with
the samples. The ALS Global document internal standards and blanks consistent with
QA/QC protocols are considered adequate by G. Artmont, the qualified person for this news
release.
ALS Global is completely independent of the qualified person described in this news
release in all aspects. ALS Global is a fully certified,
internationally recognized analytical laboratory for the mineral industry.
We seek Safe Harbor.
