PAST PRODUCING MINE & HISTORIC SAMPLING RESULTS:

HIGHLIGHTS FROM 1995 PROGRAMS & 2005

KENT EXPLORATION CHIP SAMPLES 170g/t AU ON VEIN 100ft LEVEL

OF ROSEBUD MINE OVER INTERVAL OF 0.46m

Vancouver, B.C. (May 12, 2020) Kingman Minerals Ltd. (TSX-V:KGS)(FSE:47A1) (“Kingman” or the

“Company”) is pleased to provide shareholders with the third in a three part series reviewing the

historic gold mining operations and prospects within the Mohave Project.

The Mohave Project (the “Project”) is located in the Music Mountains in Mohave County , Arizona and is

comprised of 20 lode claims which are inclusive of the past producing Rosebud Mine (the “Rosebud”), eight

separate veins and one prominent double vein which extend from the northwest corner to nearly the

southeast corner of the claims block. High grade gold and silver veins were discovered in the area in the

1880’s and w ere mined mainly in the late 20’s and 30’s. Underground development on the Rosebud

property included a 400-foot shaft and approximately 2,500 feet of drifts, raises and crosscuts.

In 1995, an exploration program was conducted by Kinntaki Resources in which 135 surface samples were

collected. Significant gold and silver results near the Rosebud Mine are shown in the table s below. The

information contained in this news release is historical in nature but was extracted from the NI 43-101 report

by qualified person, Edward Harrington, P.Geo. and is believed to be accurate and unbiased based on

comparison with previous and subsequent reports on the subject property.

Tables 1 and 2 – Kinntaki Resources 1995 rock sampling results (from Harrington, Edward., 2005,

Technical Report on the Rosebud Property, Mohave County, Arizona: prepared for Kent Exploration Inc.,

66p.).

The Kingman Minerals qualified person has not verified the results of the 1995 surface rock sampling listed

in Tables 1 and 2. Additional sampling would be required to verify the data.

Induced polarization, resistivity and magnetic geophysical surveys were conducted by D. Mark,

geophysicist, P.Geo. The results indicate the presence of sulphide mineralization along strike and at depth

from known areas of anomalous gold and silver. Therefore, it may be assumed that drilling in these areas

might intersect mineralized shear zones at depth. Seven target areas (Z1 to Z7) have been identified, based

on the combination of geochemical and geophysical data (Figure 3).

While much of the field work was conducted in 1995 and could be considered as historical in nature, m ost

of the technical information contained in this news release came directly from the NI 43 -101 compliant

report by Edward Harring ton (2005) for Kent Exploration Inc. The Kingman Minerals qualified person has

not verified the results of the geophysical work shown in Figure 1. Repeat magnetic, IP and resistivity

surveys would be required to verify the data.

In 2005, Kent Exploration Inc., following the recommendations of Ed Harrington P.Geo, obtained access

and completed an underground rock sampling program. Ropes and safety harnesses were used to access

the 100ft level by way of the main production shaft. This was the first undergrou nd sampling verification to

be conducted since L.A. Bayrock in 1983 and 1984.

foot level of the Rosebud Mine. Sample results are in Table 3.

According to Harrington, “all samples returned values anomalous in one or more of gold, silver, lead and

zinc and are considered to be significant.” Selected results from his 2005 report are as follows:

Table 3 –Underground rock sampling results from 2005 exploration program conducted by Kent

Exploration Inc. (from Harrington, Edward., 2005, Technical Report on the Rosebud Property, Mohave

County, Arizona: prepared for Kent Exploration Inc., 66p.).

The highest chip sample from the 100ft level of the mine returned a gold value of 170.5 g/t and 217

g/t silver over 0.46m. The highest silver value achieved was 709g/t from a stock pile grab sample.

The Kingman Minerals qualified person has not verified the results of the Kent Exploration 2005

underground sampling. Access to underground workings and additional sampling would be required to

verify the sample results in Table 3.

The 2005 report stated that:

• limited previous mining on the Property has defined both gold and silver mineralization associated

with shearing;

• limited previous mining on the Property has defined both gold and silver mineralization associated

with shearing;

• historical and contemporary surface and underground sampling has indicated potentially

economic gold and silver grades;

• several zones known to host gold and silver mineralization have been identified;

• underground sampling carried out in 2005 returned significant gold and silver values, and showed

that the main production shaft and underground workings on the 100-foot level are accessible and

generally in good condition;

• an IP/resistivity survey has indicated that zones of mineralization may extend along strike beneath

alluvial cover, and be present at depth; and

• a suite of elements commonly accompanying porphyry -style mineralization is shown by rock

sampling assay results to occur on the Rosebud property.
