California Gold Announces New Discovery with Highest-Grade Assays Ever from Queen Specimen Zone - Intersects 20.75 g/t Au Across 1.5 m, Hosted Within a Broader Zone Grading 4.1 g/t Au Across 10.7 m at Fremont (True Widths are Approximately 82% of Reported Intervals)

Toronto, Ontario (FSCwire) - California Gold Mining Inc. (“California Gold” or the “Company”) announces the fourth set of assay results from the ongoing resource drilling program at the Queen Specimen zone at its flagship Fremont Project (the “Project” or “Fremont”) in Mariposa County, California. Assays for the first nine holes from the current program at Queen Specimen were announced in separate press releases dated February 8, 2018, February 21, 2018 and March 5, 2018,

Today’s results advance the Company’s main objective of generating a second shallow mineral resource on the Property covering the newly identified Queen Specimen mineralized zone. This zone is located in the north-west portion of the Property, and constitutes roughly 750m of strike length, out of the total four kilometers strike of the Mother Lode shear zone (the “Shear Zone”) on the Property.

Vishal Gupta, California Gold’s President and CEO, said, “Today’s assays are the highest-grade results received from the Queen-Specimen zone to-date, and amongst the highest-grade results from the entire Fremont Property, including the Pine Tree-Josephine zone where our current NI 43-101 compliant mineral resource is hosted. It is increasingly becoming apparent that as we progress our drilling along Queen Specimen systematically from the southern end of the zone towards the centralized core of the zone, the mineralization is getting more intense. We are treating these high-grade results as a new discovery since the mineralization is hosted in a unit on the hanging wall side of the Shear Zone that has not been systematically drilled previously, and is traditionally not associated with significant mineralization. This further supports our vision that at the completion of our current drill campaign we will be able to add significantly to our resource base, and further demonstrate the continuity of near-surface mineralization along the entire four kilometres strike of the Shear Zone on the Fremont Property. It also signals that there is significant “blue sky” potential at Fremont that we will be eagerly exploring.”

Highlights from today’s two holes at Queen Specimen are displayed in the following table. A map depicting the location of the major mineralized zones at Fremont, the plan-view collar locations for the two drill holes, and the corresponding geological cross-sections can be viewed in Appendices A, B and C, respectively.

Notes: Composite grades are length weighted to interval width. Composite true widths for both QS-DD-18-013 and 012A are approximately 82% of the reported intervals.

The Company’s current NI 43-101 open pit-constrained mineral resource of 515,000 ounces grading 1.71 g/t gold in the Indicated category, and an additional 364,000 ounces grading 1.44 g/t gold in the Inferred category, only encompasses the Pine Tree-Josephine zone within the Property (the NI 43-101 Technical Report is available on SEDAR and at the Company’s website www.caligold.com). The Pine Tree-Josephine zone hosts two historical underground gold mines, and covers a strike length of roughly one kilometre, out of a total strike of four kilometres over which the Shear Zone is interpreted to extend on the Property.

Discussion of the Queen Specimen Drill Holes

The two holes discussed in this press release were drilled as part of the resource drilling campaign at the Queen Specimen mineralized zone that commenced on December 2, 2017. The program is estimated to consist of 50 to 60 HQ-sized (2.5” diameter) diamond drill holes, totalling roughly 10,000m of drilling, with an average drill hole length of 180m.

The same lithological sequence was observed in these drill holes as with previously analyzed drill holes in the Queen Specimen deposit, and in the Pine Tree–Josephine deposit, including a sequence of metavolcanic mafic rocks overlying a melange of serpentinized ultramafic rocks. These are separated from the underlying meta-sedimentary rocks of the Mariposa Formation by a zone of highly sheared and serpentinized phyllonite that is characteristic of the Shear Zone.

In addition to the sequence stated above, a zone of fault-emplaced sediments is apparent within the hanging-wall mafic metavolcanic rocks. This stratigraphic repetition may be due to thrust faulting or folding associated with dextral movement along the Shear Zone that has been observed in airborne magnetic data acquired for the Fremont Project in 2016.

QS-DD-18-013

Drill hole QS-DD-18-013 was drilled at an azimuth of 235° and an inclination of -75° to a total depth of 238.7m. This hole intersected significant mineralization across four discrete zones downhole.

The uppermost unit was intersected from 66.5m to 80.2m depth with an average grade of 1.64 g/t Au. The mineralization within this interval is associated with albitized structural mélange with pervasive carbonate alteration and faulting.

The second unit was intersected from 185.3m to 196.0m depth with an average grade of 4.08 g/t Au, and is associated with faulted sedimentary rocks and quartz-ankerite veining, in contact with albitized serpentinite.

The third unit was intersected from 202.1m to 214.0m depth with an average grade of 0.61 g/t Au, and is associated with the contacts of intercalated mafic dykes and the sedimentary unit on the footwall side. The dykes have pervasive sericitic alteration with euhedral sulphide mineralization.

The fourth mineralized unit was intersected from 221.6m to 229.2m depth with an average grade of 0.57 g/t Au associated with Mariposa Formation Sediments with mafic dykes and clustered sulphide mineralization.

QS-DD-18-012A

Drill hole QS-DD-18-012A was drilled at an azimuth of 235° and an inclination of -52° to a total depth of 192.6m. This hole intersected significant mineralization across two discrete zones downhole.

The uppermost unit was intersected from 62.8m to 67.4m depth. The average grade over this interval is 1.47 g/t Au. The second unit was intersected from 142.3m to 146.9m depth with an average grade of 3.26 g/t Au. The mineralization within both these zones is associated with contacts between albitized serpentinite and faulted sediments. The mineralized intervals are sheared with fine sulphide mineralization.

Description of Quality Assurance & Quality Control (QA/QC) Procedures

The laboratory being used for assay analyses is American Assay Laboratories Inc. (“AAL”) based in Sparks, Nevada (ISO/IEC 17025:2005 Certified).

Prior to transportation of core samples to AAL, all core processing is conducted at the Project site in an enclosed 6,000 sq. ft. office facility. All diamond drill core is logged, photographed and split using core saws. Core from entire holes is being sampled every five feet to compare with the historic RC hole assay intervals. Additionally, sub-samples are being collected within the planned five foot intervals where important geological or mineralization contacts occur to allow better discrimination within the geological model. The minimum sample interval is 1.5 feet.

One half of the split core is transported to AAL by Company employees for prep and analysis. The other half of the core is stored at the Company core storage facility for future inspection and assay verification. All gold analyses of strongly mineralized samples utilize the screened metallics fire (SMF) assay method with a gravimetric finish. At the laboratory, the entire sample is crushed to 90 percent minus ten-mesh. A rotary splitter is used to obtain a 500 gram sample for pulverising. The screened metallics are collected as the plus fraction from a 150-mesh screen at the lab. The plus 150-mesh fraction is fire assayed in its entirety. Two separate one-assay ton fire (1ATF) analyses of the minus 150-mesh fraction are performed and arithmetically averaged. The minus and plus 150-mesh results are then combined for a total screened metallics fire assay.

A full QA/QC program, involving insertion of appropriate blanks and standards is being employed with acceptable results.

Mr. Gupta is a P.Geo. registered with the Association of Professional Geoscientists of Ontario (APGO), and a Qualified Person (QP) as defined under National Instrument 43-101.
