Xiana Announces Exploration Success at New Near Term Production Area of Mina San Andres

Vancouver, September 26, 2019 - Xiana Mining Inc. (TSXV: XIA) ("Xiana" or the "Company") is pleased to announce an exploration success at the San Andres production development tunnel at Minera Altos de Punitaqui ("MAP").

The 4.5-metre by 4.5-metre development tunnel at our San Andres project intersected well mineralised copper sulphide mineralisation after 324 metres of ramp development. Continuation of this ramp to the south and to depth will generate sulphide feed material that can be directly dispatched to our central 3,600-tonne-per-day milling complex situated 25 km to the south. The San Andres body is recognised as the upper section of the Cinabrio mine that is currently in active production. The top of the Cinabrio body was offset 600 metres to the west by a low angle fault.

Development of Mina San Andres has been at the core of Xiana's strategy since acquiring MAP in November 2018 and aims to add to the production base through organic growth within our own properties.

The mineralised material at San Andres is hosted in a sub-vertical stratabound sedimentary sequence within a volcanic package of andesites and volcaniclastics. Mineralisation is well contained within this sedimentary package. The results come following 6 months of detailed mapping and structural evaluation of the Punitaqui district that has allowed Xiana to develop a comprehensive geological model of the geochemical and structural evolution of these deposits in the Punitaqui district.

The Cinabrio orebody has been in production for 9 years and is predominantly comprised of Cu-Ag mineralisation. We are currently encountering Cu-Au mineralisation associated with potassic alteration lower down in the system. The lower parts of the Cinabrio orebody will be subject to a 5,000-metre underground drill program to further test the extent of the Cu-Au mineralisation.

A 10,000-metre drill program will commence in October 2019 from surface platforms on the extensions of the deposit to the south of the ramp development at San Andres. This is in conjunction with the resource drilling that has already commenced at Cinabrio earlier this year in relation to the legacy blocks.

Carlos Ballon, Chairman & CEO, commented, "We are extremely encouraged by this exploration success at Mina San Andres. The development and commencement of production at San Andres in the near-to-medium term will add to MAP's production profile and enhance cash flow potential through organic expansion. We continue to believe in the district wide potential of MAP and the positive results from San Andres are a testament to the high-quality geological model developed by the team that now provides a pathway towards detailed drilling and exploration. We continue to deliver on our strategy of transitioning Xiana to a mid-tier copper producer in the medium term."

San Andres QA/QC

During 2017, 2,606.52 metres of NQ diamond drill holes were completed in 7 holes, SAS-17-01 to SAS-17-07. These were assayed at the in-house laboratory that is not ISO17025 certified. A total of 360 primary samples and 67 control samples are being dispatched to ALS laboratories in Chile.
