Rosita Increases Land Position at Moosehead Project; Rosita Establishes Moosehead Gold Inc. as 100% Subsidiary

Edmonton, AB -- August 22, 2018 -  Rosita Mining Corporation (OTC:MDLXF) (TSX-V:RST) ("Rosita" or the "Company") is pleased to announce that it has increased its land holding in Newfoundland by adding to the previously announced Marilyn Three Property (announced August 14, 2018). The additional land package was staked to cover prospective geology along the contact of the Botwood Group and the Mount Peyton Intrusive. Also, the additional claims cover parallel epithermal textured boulder trains and the possible strike extension of the in situ epithermal system.

As previously announced: The Marilyn Three Property is located within a northeast-trending belt of Silurian volcanic, volcaniclastic and sedimentary rocks, adjacent to a large bimodal intrusive. This intrusive (The Mount Peyton complex) is thought to be responsible for the large regional fault structure located within the larger area and within the property. The project now consists of 161 claim blocks representing exclusive exploration rights to a land package of approximately 9,945 acres (4,025 hectares) and lies within the same belt of rock and on trend with the mineral license hosting Sokoman Iron Corp.'s recently announced discovery hole (Sokoman Iron Corp. (SIC-TSXV) news release dated July 24, on its Moosehead gold project, where Sokoman Iron reported a drill intersection of 44.96 grams per tonne gold over 11.9 metres). (See attached map). Additionally, within the property, recent work has identified quartz sub-crop blocks (enriched in silver, arsenic and antimony) with assays up to 4.8g/t Au. These blocks are located approximately 150m west of a recently identified 10-15m wide epithermal vein system in outcrop. Appearances and textures indicate that the vein outcrop is a fully preserved epithermal quartz veined system with potential significant grades just below the surface within the boiling zone.

Rosita is responsible to the Vendors for the additional staking costs for the additional 57 claim blocks.

In addition, Rosita announces that it has established a wholly-owned subsidiary named Moosehead Gold Inc. to hold its property in this emerging gold exploration play.

The technical contents of this news release were approved by John F. Cook, MIMMM, a qualified person as defined by the National Instrument 43-101. The properties have not been the subject of an NI 43-101 technical report.

The Company Announces Memorandum of Understanding

Edmonton, AB -- July 30, 2018 -  Rosita Mining Corporation (OTC:MDLXF) (TSX-V:RST) ("Rosita" or the "Company") and its Nicaraguan subsidiary ALR Nicaragua SA (“ALR”) is pleased to announce it has entered into a Memorandum of Understanding which could lead to a new Joint Venture Agreement (“JV”) with CENTURY MINING SA a Nicaraguan mining company (“CENTURY”). This JV pertains to the Rosita D Concession and the Santa Rita Stockpile treatment Project (“Santa Rita”).

CENTURY has agreed, subject to the JV, that after an initial US$1.5 million investment, for a 13% interest in the Concession, they will invest a further US$7 million to build the treatment plant for a total interest in the Concession of 75%. Currently, a JV between Rosita 67% and Calibre 33% exists and will remain on a diluted basis for the remaining 25% and all three parties will be involved in the revised JV with participating interests.

CENTURY is a company formed for mining interests in Nicaragua. It is associated with other companies with business interests in Nicaragua and other parts of Central America. This is coupled with extensive Chinese and US business interests. A CENTURY investor and technical team has visited the Santa Rita site.

The formal mine permit application document for Santa Rita, as announced in December 2017 (see News Release dated December 14th 2017) has been submitted to the regulators: - La Secretaria de Recursos Naturales y Ambiente (“SERENA”), as of July 24th, 2018.

The Company announced its positive Preliminary Economic Assessment (“PEA”) on Santa Rita (see News Release dated March 9th, 2017). The PEA was preliminary in nature and it includes Indicated and Inferred resources in the Stockpiles and Tailings Resources as disclosed by the Company's February 8, 2016 NI 43-101 Technical Report (filed on SEDAR March 22nd 2016). The Inferred Resources are too speculative geologically to have economic considerations to be applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

The Resources estimated and the results of the testwork and engineering previously disclosed, allowed the following Project to be defined for the PEA:

Anticipated Life of Mine of 10 years, utilizing 4.67 million tonnes of the material included in the resource tabulation categorized as Indicated Mineral Resources grading at 0.51 grams per tonne gold, 8.2 grams per tonne silver and 0.59% copper and 1.53 million tonnes categorized as Inferred Mineral Resources grading at 0.61 grams per tonne gold, 11.3 grams per tonne silver and 0.65% copper.
Anticipated capacity of the Treatment plant (milling plus heap leach) of 1,000 tonnes per day for the first 3 years, expanding to 2,000 tonnes per day for the subsequent 7 years.

The metal prices assumed for the economic Model are: -

Gold: USD$1250 per ounce
Silver: USD$18 per ounce
Copper: USD$2.50 per pound.

Other criteria, assumptions and conclusions from the PEA may be summarised:

Pre-production capital costs including 30% contingencies, $11.4 Million
Total capital over life of mine including 30% contingencies, $26.1 Million
Operating costs over the life of mine per tonne of throughput, $ 18.50 per tonne
The Nicaraguan royalty rate of 3% NSR and 0.5% to an independent 3rd party applied to all saleable products.
The Nicaraguan income tax rate of 30% after depreciation of fixed assets at 10%
IRR after all government taxes 41%;
NPV at 7%, after all government taxes $33.9 million;
Pay back of initial pre-production capital after all taxes 2.6 years
If this transaction, which is subject to the JV Agreement, goes ahead and CENTURY makes the proposed investments, Rosita will be diluted to a minority interest. The Company believes that the proposed investment is positive for the Project as designed by Rosita.

As the investment continues and the potential dilution is clarified, Rosita will disclose the necessary steps to re-establish an alternative asset to meet its Continued Listing Requirements. (CLR) as outlined by the TSX-V.

Rosita Mining Samples High Grade Copper-silver-gold Values at Tipispan, Nicaragua

Edmonton, AB -- February 15, 2018 -  Rosita Mining Corporation (OTC:MDLXF) (TSX-V:RST) ("Rosita" or the "Company") is pleased to report that sampling from new workings developed on the Company's Tipispan target by local artisanal miners, has returned high grading copper and precious metals values.
Sampling Highlights

321680: 14.17% Cu, 321 g/t Ag, 0.139 g/t Au,1.19% Zn
321681: 14.59% Cu, 331 g/t Ag, 0.489 g/t Au, 0.44% Zn
321682: 14.86% Cu, 260 g/t Ag, 0.805 g/t Au, 3.48% Zn
321686: 12.98% Cu, 967 g/t Ag, 5.7g/t Au, 11.35% Zn

A complete table of sampling results is included in the photograph below, entitled 'Tipispan Sample Locations'.

A working map is also included that shows the workings with relation to trenches and holes from the Tipispan area.

Tipispan Target Area

Rosita staff in Nicaragua sampled newly exposed mineralization at the base of a new pit excavated by local artisanal miners on the Tipispan target. Tipispan is one of multiple exploration targets on the Company's Santa Rita project near Rosita, Nicaragua.

A small open pit was excavated to a depth of approximately 20 metres ("m") partially along a trench completed by Rosita several years ago to test this area. The new excavation exposed a broad zone of oxide mineralization at the base of the pit from which the sampling took place. A photograph of the open pit and sample locations is available below.

In 2015, Rosita completed a fence of four drill holes approximately 80 m south of the location of the new sampling results. Of these holes, drill hole 5783 intersected 16.5 m of near surface mineralization grading 1.43% copper and 34.29 g silver per tonne from 13.5 m to 30 m vertical depth.

Importantly, the hole ended in mineralization with the last 1.5 metre sample assaying 1.58% copper and 24.7 grams silver per tonne. Mineralization occurs primarily as chalcopyrite and arsenopyrite in a quartz monzonite intrusive.

The hole was part of a short four reverse circulation hole program designed to follow up encouraging trench results completed in 2012 and 2013 by a Rosita's predecessor company, Alder Resources, which returned 5.21% copper, 4.6 grams gold and 144 grams silver across 12 metres.

The discovery of mineralization north of the last drilling suggests the mineralized zone at Tipispan remains open towards the northwest and has now been defined along a strike length of approximately 200 m.

John Cook, President and CEO, commented, "The discovery of new high grading, near surface, mineralization at Tipispan is indeed encouraging and has the potential of adding additional resources to the emerging plan we are developing, based on stockpiles at Santa Rita."

2018 Operating Plan

Rosita's strategic focus in 2018 is to continue with the permitting and engineering of the treatment plant for the Stockpile Project, as announced in the press release dated December 14, 2017. The preparation of the Environmental Impact Study is continuing as planned.

Tipispan is one of the primary exploration targets in the Rosita D Concession. Rosita plans to carry out limited exploration on the Tipispan Project and other known and defined exploration targets.

Santa Rita Project Highlights

The Santa Rita project was the subject of a Preliminary Economic Assessment, ("PEA") which was completed in March, 2017 and the full results of which are available at www.sedar.com
PEA highlights are summarized below:

Anticipated Life of Mine of 10 years, utilizing 4.67 million tonnes of the material included in the resource tabulation categorized as Indicated Mineral Resources grading at 0.51 grams per tonne gold, 8.2 grams per tonne silver and 0.59% copper and 1.53 million tonnes categorized as Inferred Mineral Resources grading at 0.61 grams per tonne gold, 11.3 grams per tonne silver and 0.65% copper.
Anticipated capacity of the treatment plant (milling plus heap leach) of 1,000 tonnes per day for the first 5 years, expanding to 2,000 tonnes per day for the subsequent 5 years.
The metal prices assumed for the economic model are:

Gold: USD$1250 per ounce
Silver: USD$18 per ounce
Copper: USD$2.50 per pound.
Other criteria, assumptions and conclusions from the PEA include:

All monetary amounts are in USD.
Pre-production capital costs including 30% contingencies, $11.4 Million
Total capital over life of mine, $26.1 Million
Operating costs over the life of mine per tonne of throughput, $ 18.50 per tonne
The Nicaraguan royalty rate of 3% NSR and 0.5% to an independent 3rd party applied to all saleable products.
The Nicaraguan income tax rate of 30% after depreciation of fixed assets at 10%
IRR after all government taxes, 41%;
NPV at 7%, after all government taxes, $33.9 million;
Pay back of initial pre-production capital after all taxes 2.6 years
Quality Assurance-Quality Control

All samples were collected and transported by Rosita employees to the Bureau Veritus Mineral Laboratories in Managua, Nicaragua for preparation. Samples were assayed in Vancouver using standard fire assay methods with AAS finish for Au and Aqua Regia digestion ICP-ES analysis for Cu and Ag. Certified standards, blanks and duplicates were inserted by Rosita in the sample stream at a rate of one per 30 samples.
