Cardero Receives Positive Sampling Results for the Ledgend Nickel-Cobalt Massive Sulphide Project
Vancouver, British Columbia--(Newsfile Corp. - November 21, 2017) - Cardero Resource Corp. (TSXV: CDU) (FSE: CR5) ("Cardero" or the "Company") announces receipt of positive surface exploration results for the Ledgend nickel-cobalt property in south eastern British Columbia ("Ledgend" or the "Property").Ledgend is one of five properties in the Kootenay project that together total approximately 8,000 hectares (Figure 1).Cardero completed soil, silt and rock sampling on Ledgend in the fall of 2017, collecting 1,218 samples which have produced significant anomalies for follow-up work.
The properties are within prospective Lardeau Group metamorphic rocks, the host of numerous volcanogenic massive sulphide deposits, including the past-producing Goldstream mine located north of Revelstoke.The Ledgend property is the most advanced, with exposures of massive and semi-massive sulphides and significant Ni-Co±Cu±Zn soil anomalies that are ready for trenching and geophysics.Cardero soil sampling expanded on previous sampling completed in 2016 ("North Grid") and added a second grid 1.8 kilometres to the south ("South Grid").
North Grid Anomalies
The North Grid (Figures 2 and 3) generated new anomalies both east and west of the original central anomaly.This grid, centred on the discovery showing, now covers an area 1100 by 2000 metres at 25 metre sample spacing on 100 metre spaced lines.The central nickel-cobalt ("Ni-Co") ("Central Zone") soil anomaly is 800 metres in length extending to the southeast of the showing, with the peak of the anomaly (values up to 0.84% Ni, 0.025% Co) located about 200 metres southeast of the massive sulphides in the discovery outcrop.This anomaly is associated with float of the same talc-tremolite-actinolite schist that occurs as the footwall to the massive sulphides, and which is the altered remnant of high Ni-Co ultramafic rocks.Trenching of the anomaly is planned to test Cardero's interpretation that the source of the nickel is buried massive sulphides.
About 400 metres to the north of the discovery showing, a separate Ni-Co peak at the north end of the anomaly occurs in a recessive area below a cliff of siliceous biotite schist. The same schist forms a large cliff north of, and apparently above, the larger anomaly peak to the south (Figure 3).The two Ni-Co peaks are joined by an adjacent copper anomaly that, at the north end, can be attributed to thin layers of outcropping semi-massive sulphides within quartzite at the Road Showing (Figure 3).Grab rock samples indicate the layers are relatively high in gold (ranging from 0.17 — 0.46 g/t), copper (up to 0.1%), manganese and phosphate, but low in nickel and cobalt.
Northwest trending Cu-Zn-Co-Ni anomalies occur along the western and eastern margins of the soil grid (Figure 3). The stronger eastern anomaly ("East Zone") has the most anomalous copper, cobalt, and nickel outside of the Central Zone. Any outcrops within the anomaly remain to be mapped and sampled.
The West Zone is a two kilometre long, Cu-Zn ± Co-Ag anomaly open to the north, south and southwest.
South Grid Anomalies
The South Grid, which covers one kilometre of the southern strike extension from the northern grid, generated a broad, 300 by 600 metre Ni-Co-Cu anomaly that is open to the south and west (http://www.cardero.com/s/kootenay_project.asp). Levels of nickel and cobalt are lower than the north grid, but the area is less steep and depth to bedrock is likely greater.This grid will be extended to the north and southwest in the next field season.

About Ledgend Property
The Ledgend Property has the first documented occurrence of nickel-cobalt bearing massive sulphides in the region. The mineralization was first described in 1998 by the B.C. Geological Survey as outcropping massive pyrrhotite with nickel and cobalt minerals.The mineralized horizon can be traced in anomalous soil samples and rock float over hundreds of meters along strike.In 2016, the underlying owners located float boulders from the discovery area and grab samples of massive pyrrhotite—pyrite float returned values of 0.15 to 0.76% nickel (Ni) and 0.01 to 0.09% cobalt (Co), as well as up to 0.53% chrome and anomalous copper and zinc.
In October 2017, the discovery outcrop was cleaned and chip sampled perpendicular to foliation, returning 4 metres of 0.22% Ni and 161ppm Co (Plate 1), with a one metre sample running 0.39% Ni and 0.028% Co. A 20-30cm layer of massive to semi-massive pyrite-pyrrhotite occurs between an upper horizon of siliceous biotite schist and lower horizon of talc-tremolite schist. True widths should be close to sample widths, but might vary significantly due to the tight folding.
The mineralization is hosted by northwest-trending, tightly folded sericite and biotite schists, quartzite, and talc-tremolite schist of the Index Formation, a member of the Lardeau Group. Graphitic and manganiferous layers are particularly anomalous in metals, and thought to be seafloor exhalatives generated by submarine hydrothermal fluids. The rock types and style of mineralization are most similar to the Outokumpu and Talvivaara districts in central and eastern Finland.
Exploration Potential
Cardero believes the metavolcanic and metasedimentary units of the southern Lardeau Group to have excellent potential for hosting volcanogenic massive sulphides ("VMS") with significant nickel-cobalt (± copper-zinc) content.The other known VMS occurrences in the belt were either discovered in areas of good rock exposure, at high elevations, or by chance during construction of forestry roads.The heavily vegetated low-elevation regions are under-explored, and few previous workers in the area recognized the potential for nickel-cobalt mineralization.Past exploration has focussed on lead-zinc- silver replacement and silver-gold vein deposits.
Note that the exploration results described here for the Kootenay Project are preliminary in nature and not conclusive evidence of the likelihood of a mineral deposit.

Sampling Procedures and Quality Assurance and Quality Control
The work program at Ledgend was designed and supervised by M. McClaren, P.Geo., J.M. Dawson, P.Eng., and John Drobe, P.Geo., the Company's Chief Geologist.Soil samples were taken from the 'B' horizon whenever possible and were collected using a mattock or shovel. Sample sites were labelled with blue and orange flagging tape with the number recorded on the tape.Soil samples were placed in waterproof kraft envelopes, after which samples were dried and collated.All soil samples were then shipped in sealed bags to ALS Minerals laboratories in Kamloops or North Vancouver, B.C.The samples were dried at <60 degrees C. and sieved to -180 microns (Prep 41), then analysed by ICP-MS for 51 elements (method AuME—TL43). Over-limit gold results (>1ppm) were repeated by method Au-AROR43.
This sampling program did not include a comprehensive QA/QC programme; however, ALS Minerals is an ISO 9002 registered laboratory and inserted blanks, standards and duplicates following their QA/QC protocol. In addition, follow-up field duplicate samples were collected from the anomalous soil lines, both high and low, and the results returned satisfactory values.
