STRONG INITIAL DRILL RESULTS INCLUDING 5.5 METRES @ 30.1G/T AU INTERSECTED

AT THOR’S SEGILOLA GOLD PROJECT

Thor Explorations Ltd. (TSX VENTURE: THX) (“Thor” or the “Company”) is pleased to pleased to announce

very encouraging results from its first set of drill results from its ongoing diamond core drilling program on its

100% owned Segilola Gold Project in Nigeria. The Probable reserve at Segilola comprises 448,000 ounces

of gold grading 4.2g/tAu within a global resource base of 862,000 ounces gold.

The Company is also pleased to announce that it has completed the metallurgical drilling program and is

progressing through the exploration and infill programs that form part of its Definitive Feasibility Study (DFS)

and pre-development workstreams at the Segilola Gold Project.

Drilling to date has targeted less defined areas of the open pit resource and Thorʼs management consider

the assay results received to date are likely to result in an upgrade of the open pit resource and reserve.

Highlights include:

• SGD171: 5.9 metres at 16.3g/tAu including 4.4 metres at 23.4g/tAu

• SGD173: 5.5 metres at 30.1g/tAu including 1 metre at 117.6 g/tAu

• SGD174: 10.8 metres at 9.7g/tAu including 0.5 metres at 151.2 g/tAu

• SGD178: 25 metres at 3.4g/tAu

Segun Lawson, President & CEO, stated:

"We are extremely encouraged by these drill results and equally excited by the pending results on our Segilola

Project. As part of our DFS field work, this drilling program was designed to increase the open pit head grade

from its already impressive and robust 4.2g/tAu. Drilling to date has targeted less defined areas of the open

pit resource.

We are also very encouraged with the high grade mineralisation found in the previously under-drilled “saddle”

in the central area of the resource. Follow up drilling will test the deeper high grade lodes identified in the

successful 2017 drill program which are now supported by these new results.

The Company expects to announce additional results in early May. In some holes that have yet to assayed,

such as SGD188(Figure 4), the visual indications are very encouraging. We look forward to updating the

market in May with our next set of drill results and progress on our DFS field work”

Drilling Program

The targeted outcomes of the drilling program, that is still ongoing, are to:

• Increase in open pit reserve grade as result of better definition of the higher grade zones (>10g/tAu)

of the resource

• Upgrade parts of the resource from indicated to measured classification

• Upgrade parts of the resource from inferred to indicated classification in order to be included in

reserve and mine planning studies

• Obtain further confirmation of high grade extensions of the gold-system at depth

• Provide samples for metallurgical testing

• Obtain data for open pit grade control design

The results to date (Table 1) generally confirm the high grade character of the deposit and, in particular, the

northern lode. Refer to Figures 2 to 3.

The Segilola gold deposit comprises a main footwall lode and two hangingwall lodes. Modelling of the

mineralisation intersected in SGD184 (1.5m at 6.7g/tAu) suggests that first hangingwall lode forms a

continuous mineralised structure that extends over the entire 1.8km strike length. This lode is characterized

by medium to high grade inercepts with frequent occurrences of visible gold. Analysis of grade contour

longitudinal sections (Figure 2) indicates several plunging shoots within the first hangingwall panel. Further

exploration at depth within these shoot trends is anticipated.

gram-metre contours and future drill targets

The DFS drilling program has also, in part, been designed to test grade continuity/variability over short

distances so that the optimum grade control drill spacing can be assessed. This information will be used to

underpin any parts of the resource that may be classified as “measured”. Figure 3 illustrates that good

continuity of high grade mineralization is confirmed by SGD173 which is positioned between two historic

drillholes at a typical grade control spacing of about 10m. Geostatistically, this may reduce the nugget effect

and thus possibly enable the classification of “measured” to be assigned to the relevant parts of the resource.

DFS Workstreams

Thor is also pleased to announce the following highlights from its ongoing DFS workstreams:

• Metallurgical test work commenced by Independent Metallurgical Operations (IMO) Perth. A

representative sample totalling over 500kg has been obtained for metallurgical testwork. Two

additional twin holes SGD175 and SGD176 were also completed to provide whole core samples for

metallurgical variability testing.

• Waste rock and tailings characterization test work underway with IMO

• Geotechnical and resource infill and extensional drilling continuing

The DFS workstreams are targeted towards de-risking and optimising the Project following the completion of

the Preliminary Feasibility Study (“PFS”) in October 2017.

The targeted outcome of the metallurgical testwork program is to optimise the PFS process flowsheet, with

the expected inclusion of a gravity recovery circuit and investigation of other identified opportunities for

process design enhancements, focussed on operational efficiency, reducing operating cost and increasing

process recoveries, in order to finalise DFS process design criteria.

The targeted outcomes of the geotechnical drilling and phases one and two of the resource drilling are to

improve project definition, increase resource ounces and reduce mining waste tonnages, resulting in further

enhancements to the open pit project economics.

Drilling and Sampling Procedures

All drilling has been undertaken with an Atlas Copco CS-14 diamond rig. Sampling is predominantly quarter-

core HQ. On occasions where NQ coring was necessary, half -core samples were taken. Core logging,

photography and cutting takes place at Thor’s exploration compound in the nearby township of Ilesha. Strict

QAQC procedures are followed with an industry -standard schedule of certified standards, blanks and

duplicates. Samples are transported under supervision directly to the MS Analytical sample preparation

laboratory in Abuja, Nigeria from where the sample pulps are couriered to Canada. Analyses are carried out

by MS Analytical (Vancouver) using the FAS-221 (fire assay, 50g charge) method. A metallic screen fire assay

(MSC-150 1,000g fire assay) is carried out on samples that return an initial fire assay result of >10g/tAu. To

date, the metallic screen fire assay results correlate to within 99% of the normal fire assays.
