Caledonia Mining Corporation Plc: Resource Update at the Blanket Mine, Zimbabwe

SAINT HELIER, CHANNEL ISLANDS--(Marketwired - July 28, 2016) - Caledonia Mining Corporation Plc ("Caledonia" or the "Company") (CAL.TO)(CALVF)(CMCL.L) is pleased to announce an increase and upgrade to the resource base at its 49% owned subsidiary, the Blanket Mine in Zimbabwe.

Based on the diamond core drilling that has been done at depth below the Blanket Section over the past half year, 343,000 tonnes have been upgraded from the Inferred to the Indicated Resource category and an additional 1,276,000 tonnes of new inventory has been added to Inferred Resources.

This upgraded Indicated Resource of 343,000 tonnes, combined with the resources upgraded during 2015, have increased the quantum of reserves and indicated resources that may be used in the life of mine plan from 2,934,000 tonnes used for the Technical Report prepared by Minxcon in December 2014, to 4,889,000 tonnes currently and represents an increase of 67% per cent in terms of mineable tonnes and hence in the life of the mine.

Blanket Quartz Reef		611,000		3.82		5.80		103,000
No. 1 Orebody		326,000		6.07		5.58		50,000

The additional inferred resources in the Blanket section doubles the quantum previously estimated from this section of the mine.

After the update announced today, Blanket Mine's resources have increased both in terms of Indicated Resources and Inferred Resources; see new totals in the following table. The decline in Measured Resources is due to the production depletion for the first half year and will be recomputed at the end of the year.

Blanket Total Resources
Mineral Resource Category		Tonnes		Grade (g/t)		Contained Gold (oz)
Measured Resources		1,177,079		4.01		151,657
Indicated Resources		3,677,828		4.31		509,222
Total M&I		4,854,907		4.23		660,879
Inferred Resources		3,862,991		5.01		622,613

All resources for Blanket are shown on a 100% basis, Caledonia owns 49% of Blanket

Commenting on the resource upgrade, Steve Curtis, Caledonia's President and Chief Executive Officer said:

"This upgrade reflects the ongoing focus on resource development at Blanket mine. It should be noted that the upgrades are only in the Blanket section of the mine and that further resource upgrades in the AR South, AR Main and Eroica sections will be released in the second half of the year.

"The upgrade of approximately 343,000 tonnes from Inferred Resource to Indicated Resource underscores the overall confidence level of Blanket's resources. The significant increase in new Inferred Resources occurred at depth and paves the way for the phase 2 expansion program to extend mining below the current target depth of 990 m Level.

"I am confident that the life of mine will be further supplemented by resource additions and upgrades as a result of the increased exploration activity, both at Blanket and also at the satellite projects."
