Item 8.01 – Other Events

On November 13, 2009 Metalline Mining Company (“Metalline”) entered into a letter of intent (the “LOI”) with Dome Ventures Corporation (“Dome”).  The LOI outlines the terms upon which Metalline will acquire all of the outstanding shares of Dome through a merger transaction.   The LOI contemplates that Metalline will issue 54,224,561 shares of its common stock in exchange for all of the outstanding shares of Dome common stock as of the closing date.  The number of shares to be received by Dome’s shareholders will depend on the number of Dome shares outstanding at the closing of the transaction, which the parties hope will occur during the spring of 2010. In the LOI both Metalline and Dome agreed to use their best efforts to execute a definitive agreement regarding the merger by November 23, 2009.  If a definitive agreement is not executed by December 4, 2009, then the letter of intent will expire.   

The LOI provides that as a condition of the proposed merger transaction Dome will arrange for $16 million in financing.  Subject to Dome arranging for such financing, the LOI provides that Dome will make an equity investment of approximately $3 million in Metalline on or before December 15, 2009 and that these funds would be used by Metalline to fund its exploration program on the Sierra Mojada property in Mexico. At the closing of the proposed merger the Metalline securities issued to Dome in connection with the $3 million investment will be cancelled.

The merger transaction contemplated by the LOI is subject to numerous conditions precedent, including Dome arranging for financing, both parties seeking and obtaining shareholder approval, both parties satisfactorily conducting their due diligence, and both parties obtaining various other regulatory approvals.  There can be no assurance that the parties will be able to meet the conditions precedent to the transaction contemplated by the LOI.  

On November 13, 2009 Metalline issued a press release regarding the LOI, a copy of which is attached to this report as Exhibit 99.1 and incorporated herein.
