CALIFORNIA GOLD ANNOUNCES NEW HIGH-GRADE ASSAYS FROM QUEEN SPECIMEN ZONE - INTERSECTS 27.64 G/T AU ACROSS 1.2M, INCLUDED WITHIN 10.64 G/T OVER 3.4M AND 3.27 G/T AU ACROSS 10.1M
California Gold Mining Inc. has released new assay results from the continuing resource drilling program at the Queen Specimen zone at its flagship Fremont property in Mariposa county, California. Assays for the previously drilled holes from the current program at Queen Specimen were announced in separate press releases dated Feb. 8, 2018, Feb. 21, 2018, March 5, 2018, April 3, 2018, April 9, 2018, and May 2, 2018, respectively.
Today's results provide additional data in support of a second shallow mineral resource on the property covering the newly identified Queen Specimen mineralized zone. This zone is located in the northwest portion of the property and constitutes roughly 750 metres of strike length out of the total four-kilometre strike of the Mother Lode shear zone on the property.
Vishal Gupta, California Gold's president and chief executive officer, said: "We continue to set new records for the highest grades ever received at the Queen Specimen zone through our current resource drilling campaign. The three holes released today were designed to test the continuity of the newly discovered high-grade mineralization hosted on the hangingwall side of the shear zone. All three holes unquestionably achieved their design objectives and have now solidified the core of this high-grade mineralization within the Queen Specimen zone. It must be noted that all these holes are very shallow, with the deepest of them having a downhole depth of only 242.9 metres. Our next objective is to demonstrate the extent of this new discovery through along-strike stepout holes while continuing to develop a substantial shallow mineral resource for the Queen Specimen zone."
Highlights from the three holes at Queen Specimen are displayed in the attached table.

Composite true widths for QS-DD-18-019, QS-DD-18-020 and QS-DD-18-021 are approximately 77 per cent, 64 per cent and 87 per cent of the reported intervals, respectively.
The company's current National Instrument 43-101 open-pit-constrained mineral resource of 515,000 ounces grading 1.71 grams per tonne gold in the indicated category and an additional 364,000 ounces grading 1.44 grams per tonne gold in the inferred category only encompass the Pine Tree-Josephine zone within the property (the NI 43-101 technical report is available on SEDAR and at the company's website). 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 three holes discussed in this press release were drilled as part of the resource drilling campaign at the Queen Specimen mineralized zone that commenced on Dec. 2, 2017. The program is estimated to consist of 50 to 60 HQ-sized (2.5-inch diameter) diamond drill holes, totalling roughly 10,000 metres of drilling, with an average drill hole length of 180 metres.
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 metasedimentary 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 herein, a zone of fault-emplaced sediments is apparent within the hangingwall 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-18-019
Drill hole QS-DD-18-019 was drilled at an azimuth of 245 degrees and an inclination of minus 45 degreesto a total depth of 237.7 metres.
This hole intersected two zones of mineralization from depths of 62.8 metresto 65.8 metres and from 138.5 metres to 143.7 metres. The average grades over these intervals are 0.62 gram per tonne gold and 2.29 grams per tonne gold, respectively. The mineralization is associated with structural melange with sericitic alteration. Mineralization was also associated with sediments and quartz veining with silicified dike inclusions. There is fine sulphide mineralization within the intervals.
QS-DD-18-020
Drill hole QS-DD-18-020 was drilled at an azimuth of 250 degrees and an inclination of minus 64 degrees to a total depth of 210.9 metres.
This hole intersected several zones of mineralization, most notably from depths of 65.2 metres to 68.3 metres and from 163.7 metres to 173.4 metres. The average grades over these intervals are 6.14 grams per tonne gold and 1.25 grams per tonne gold, respectively. The mineralization for the first interval is associated with talc-altered serpentinite. For the second interval, mineralization is associated with intermittent quartz veining, structural melange and sediments. There was sulphide mineralization noted within this interval.
QS-DD-18-021
Drill hole QS-DD-18-021 was drilled at an azimuth of 215 degrees and an inclination of minus 55 degrees to a total depth of 242.9 metres.
***This hole intersected significant mineralization across four separate intervals. The uppermost mineralized intersection occurs from 53.6m to 57.0m depth with an average grade of 10.64 g/t Au. This mineralization is associated with serpentinite-hosted pyritic sulphide. Visible gold was observed within this interval. The second mineralized intersection occurs from 61.9m to 71.0m depth with an average grade of 1.23 g/t Au. This mineralization is associated with serpentinite and structural melange. There is quartz veining present, as well as fuchsite and sericitic alteration within the melange. The third mineralized intersection occurs from 152.6m to 163.4m with an average grade of 1.56 g/t Au. The mineralization is associated with structural melange in contact with sediments. There is massive quartz veining and significant sulphide content. The fourth intersection occurs from 166.7m to 176.8m with an average grade of 1.14 g/t Au, and is associated with sericitized structural melange in contact with a brecciated mafic dyke. Sulphide mineralization is prevalent within this mineralized zone.
Application for Industrial Hemp Cultivation Submitted to Mariposa County
The Company also announces that it has submitted an application to Mariposa County seeking approval for the cultivation of industrial hemp on the Property. The proposed operations include the construction of a 20,000 sq ft greenhouse, to be primarily utilized for the propagation of industrial hemp seeds, along with the development of a 100-acre agricultural farm for the cultivation of an industrial hemp crop, and the construction of a 5,000 sq ft facility for the processing of the crop raw material.
At present, the Company is awaiting Mariposa County's approval before making a final decision on the industrial hemp cultivation operations. If and when the approval is granted, the Company will issue a subsequent press release announcing the approval as well as updates regarding any decisions to proceed with such cultivation operations.
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.
